Grundfos Product Center 110 Grundfos GO 111 CRE, CRIE, CRNE 1 TM06 9851 0817 E-pumps without sensor are used when uncontrolled operation (open loop) is required or when there is a wish to fit a sensor at a later stage in order to enable: • pressure control • flow control • level control of liquid in a tank • temperature control • differential pressure control • differential temperature control. E-pumps without sensor are also used when a remote analog signal is connected to the setpoint input terminal. H H CRE, CRIE and CRNE pumps H set Q Q Constant pressure Fig. 2 Constant curve CRE, CRIE, CRNE with sensor H H Q set Constant flow Fig. 3 TM00 7668 1696 The CRE, CRIE and CRNE pumps are based on the CR, CRI and CRN pumps. CRE, CRIE and CRNE pumps belong to the so-called E-pump family and are referred to as E-pumps. The difference between the CR and CRE pump ranges is the motor. CRE, CRIE and CRNE pumps are fitted with an E-motor, i.e. a motor with built-in variable frequency drive. The E-pump motor is a Grundfos MLE motor. The built-in frequency converter enables continuously variable control of the motor speed. This means that the pump can be set to operate at any duty point. The purpose of continuously variable speed control of the motor speed is to adjust the performance to a given requirement. CRE, CRIE, CRNE pumps are available with a pressure sensor enabling the control of the pressure on the outlet side of the pump. The purpose of supplying the E-pumps with a pressure sensor is to make the installation and commissioning simple and quick. All other E-pumps are supplied without sensor. Q Constant curve Q TM01 0684 0808 Fig. 1 Product introduction 1. Product introduction E-pumps without sensor 3 CRE, CRIE, CRNE 1 Product introduction The pump materials are identical to those of the CR, CRI and CRN pump ranges. An E-pump is not just a pump, but a system which is able to solve application problems or save energy in a variety of pump installations. All that is required, is the power supply connection and the fitting of the E-pump in the pipe system, and the pump is ready for operation. The pump has been tested and pre-configured from the factory. The operator only has to specify the desired setpoint (pressure) and the system is operational. In new installations, the E-pumps provide a number of advantages. The integrated variable frequency drive has a built-in motor protection function which protects both motor and electronics against overload. This means that E-pump installations do not require a motor-protective circuit breaker, but only a normal short-circuit protection for the cable.

Adaptation of performance through frequencycontrolled speed control offers obvious benefits, such as: • energy savings • increased comfort • control and monitoring of the pump performance. 4 CRE, CRIE, CRNE 1 H [m] H [ft] 300 1000 800 200 Product introduction Performance range, CRE, CRIE, CRNE CRE 60 Hz 600 400 300 60 50 40 200 30 100 80 20 CRE 120 CRNE 120 CRE 150 CRNE 150 CRE 1 CRIE 1 CRNE 1 60 CRE 1s CRIE 1s CRNE 1s 40 10 CRE 5 CRIE 5 CRNE 5 CRE 3 CRIE 3 CRNE 3 CRE 15 CRIE 15 CRNE 15 CRE 10 CRIE 10 CRNE 10 CRE 64 CRNE 64 CRE 32 CRNE 32 CRE 20 CRIE 20 CRNE 20 CRE 45 CRNE 45 CRE 90 CRNE 90 30 20 2 4 6 8 10 20 40 60 80 100 200 400 600 8001000 1000 Q [US GPM] 1 2 3 4 5 6 7 8 910 10 20 30 40 50 60 7080 100 Eff [%] Q [m³/h] 80 60 40 20 0 2 4 6 8 10 20 40 60 80 100 200 400 600 8001000 1000 Q [US GPM] TM05 1598 3411 100 80 5 CRE, CRIE, CRNE 1 Application Water supply Filtration and transfer at waterworks Distribution from waterworks Pressure boosting in mains Pressure boosting in high-rise buildings, hotels, etc. Pressure boosting for industrial water supply Constant-pressure control A pump supplies tap water from a break tank to various taps in a building. The demand for tap water varies, and so does the system characteristic, according to the required flow rate. To achieve comfort and energy savings, we recommend a constant supply pressure.

Application examples As discussed earlier, speed control of pumps is an efficient way of adjusting pump performance to the system. In this section, we will discuss the possibilities of combining speed-controlled pumps with PI controllers and sensors measuring system parameters, such as pressure, differential pressure and temperature. On the following pages, the different options will be presented through examples. 6 h Fig. 5 Q1 Qmax Q TM03 0410 5004 Product introduction Applications Constant-pressure control As appears from fig. 5, the solution is a speedcontrolled pump with a PI controller. The PI controller compares the required pressure, pset, with the actual supply pressure, p1, measured by a pressure transmitter PT. If the actual pressure is higher than the setpoint, the PI controller reduces the speed and consequently the performance of the pump until p1 = pset. Figure 5 shows what happens when the flow rate is reduced from Qmax. to Q1. The controller reduces the speed of the pump from nn to nx in order to ensure that the required outlet pressure is p1 = pset. The pump ensures that the supply pressure is constant in the flow range of 0 to Qmax. The supply pressure is independent of the level (h) in the break tank. If h changes, the PI controller adjusts the speed of the pump so that p1 always corresponds to the setpoint. CRE, CRIE, CRNE 1 Product introduction Constant-temperature control Performance adjustment by means of speed control is suitable for a number of industrial applications. Figure 6 shows a system with an injection molding machine which must be water-cooled to ensure high quality production. Setpoint tsettset Setpoint PI controller Actual value trr Speed controller Injection molding machine Cooling plant TM03 0412 5004 Temperature transmitter Fig. 6 Constant-temperature control The pump will be operating at a fixed system characteristic. The controller will ensure that the actual flow rate, Q1, is sufficient to ensure that tr = tset. The machine is cooled with water at 59 °F (15 °C) from a cooling plant. To ensure that the molding machine runs properly and is cooled sufficiently, the return-pipe temperature has to be kept at a constant level, tr = 68 °F (20 °C). The solution is a speed-controlled pump, controlled by a PI controller. The PI controller compares the required temperature, tset, with the actual return-pipe temperature, tr, which is measured by a temperature transmitter TT. This system has a fixed system characteristic, and therefore the duty point of the pump is located on the curve between Qmin and Qmax. The higher the heat loss in the machine, the higher the flow of cooling water needed to ensure that the return-pipe temperature is kept at a constant level of 68 °F (20 °C). 7 CRE, CRIE, CRNE 1 Product introduction Product range, CRE Range CRE 1s CRE 1 CRE 3 CRE 5 CRE 10 CRE 15 CRE 20 Rated flow rate [US gpm (m3h)] 4.5 (1.0) 8.5 (1.9) 15 (3.4) 30 (6.8) 55 (12.5) 95 (21.6) 110 (25.0) Temperature range [°F (°C)] -4 to +250 (-20 to +121) Temperature range [°F (°C)] - on request -40 to +356 (-40 to +180) Maximum working pressure [psi (bar)] Maximum pump efficiency [%] 362 (25) 35 49 59 67 70 72 72 0 - 5.7 (0 - 1.3) 0 - 12.8 (0 - 2.9) 0 - 23.8 (0 - 5.4) 0-45 (0 - 10.2) 0-70 (0 - 15.9) 0-125 (0 - 28.4) 0-155 (35.2) 760 (230) 790 (240) 790 (240) 780 (237) 865 (263) 800 (243) 700 (213) 1/3 to 2 1/3 to 3 1/3 to 5 3/4 to 7 1/2 3/4 to 15 2-25 3-25 CRE: Cast iron and stainless steel AISI 304 ● ● ● ● ● ● ● CRIE: Stainless steel AISI 304 ● ● ● ● ● ● ● CRNE: Stainless steel AISI 316 ● - ● - ● (CRTE 2) ● (CRTE 4) ● (CRTE 8) ● (CRTE 16) ● - 3 Flow range [US gpm (m h)] Maximum pump pressure (H [ft (m)]) Motor power [HP] Version CRTE: Titanium Range CRE 32 CRE 45 CRE 64 CRE 90 CRE 120 CRE 150 Rated flow rate [US gpm (m3h)] 140 (32) 220 (50) 340 (77) 440 (100) 610 (139) 750 (170) -22 to +250 (-30 to +121) 1) Temperature range [°F (°C)] Temperature range [°F (°C)] - on request Maximum working pressure [psi (bar)] Maximum pump efficiency [%] Flow range [US gpm] Maximum pump pressure (H [ft (m)]) Motor power [HP] -22 to +250 (-30 to +121) 1) & 2) -40 to +356 (-40 to +180) - - 435 (30) 76 78 79 80 75 73 14-210 (3.2 - 47.7) 22-310 (5.0 - 70.0) 34-450 (7.7 - 102.2) 44-630 (10.0 - 143.1) 61-700 (13.9 - 159.0) 75-790 (17.0 - 179.4) 720 (220) 490 (149) 330 (101) 230 (70) 140 (43) 150 (15) 5-30 7 1/2 - 30 10-30 15-30 20-25 25-30 ● - ● - ● - ● - ● - ● - ● - ● - ● - ● - ● - ● - Version CRE: Cast iron and stainless steel AISI 304 CRIE: Stainless steel AISI 304 CRNE: Stainless steel AISI 316 CRTE: Titanium Available. 1) CRN 32 to CRN 90 with HQQE shaft seal: -4 to +250 °F (-20 to +121 °C). 2) CR, CRN 120 and 150 with 75 or 100 HP motors with HBQE shaft seal: 0 °F to +250 °F (-17 to +121 °C). 8 CRE, CRIE, CRNE 1 Motor The CRE pumps are non-self-priming, vertical, multistage centrifugal pumps.

Installation altitude is the height above sea level of the installation site. Motors installed up to 3280 ft (1000 m) above sea level can be loaded 100 %. Motors installed more than 3280 ft (1000 m) above sea level must not be fully loaded due to the low density and consequently low cooling effect of the air.

Overheating may result from excessive ambient temperatures or high altitudes. In such cases, it may be necessary to use a motor with a higher rated output. Viscosity The pumping of liquids with densities or kinematic viscosities higher than those of water will cause a considerable pressure drop, a drop in the hydraulic performance and a rise in the power consumption. In such situations, fit the pump with a larger motor.

Grundfos MLE motors are recognized under the Component Recognition Program of Underwriters Laboratories Inc. for the United States and Canada. MLE motors are equipped with a reinforced bearing system with locked bearings at the drive end, either a deep-groove ball bearing or an angular-contact bearing depending on the motor model. MLE technical data 2. MLE technical data This ensures an even uptake of the load in order to maximize the lifetime of the bearings, which are guaranteed for a minimum of 18,000 hours service life. At the non-drive end, the motors are fitted with bearings with axial clearance in order to meet production tolerances while allowing for thermal expansion during motor operation. This ensures trouble-free operation and long life.

Control of E-pumps CRE, CRIE and CRNE pumps are the ideal choice for a number of applications characterized by a demand for variable flow at constant pressure. The pumps are suited for water supply systems and pressure boosting as well as for industrial applications. Depending on the application, the pumps offer energy savings, increased comfort and improved processing. E-pumps in the service of industry The industry uses a large number of pumps in many different applications. Demands on pumps in terms of pump performance and mode of operation make speed control a must in many applications. E-pumps are ideal for and often used in the situations listed below. Constant pressure • Water supply • washing and cleaning systems • distribution from waterworks • humidifying systems • water treatment systems • process boosting systems, etc. Example: Within industrial water supply, E-pumps with integrated pressure sensor are used to ensure a constant pressure in the pipe system. From the sensor, the E-pump receives inputs about changes of pressure as a result of changes in the consumption. The Epump responds to the input by adjusting the speed until the pressure is equalized. The constant pressure is stabilized once more on the basis of the preset setpoint. Constant temperature • Air-conditioning systems in industrial plants • industrial cooling systems • industrial freezing systems • casting and molding tools, etc. Example: In industrial freezing systems, E-pumps with temperature sensor increase comfort and lower operating costs compared with pumps without a temperature sensor. An E-pump continuously adapts its performance to the changing demands reflected in the differences in temperature of the liquid circulating in the freezing system. Thus, the lower the demand for cooling, the smaller the quantity of liquid circulated in the system and vice versa. 18 Constant level • Boiler feed systems • condensate systems • sprinkler irrigation systems • chemical industry, etc. Example: In a steam boiler, it is important to be able to monitor and control pump operation to maintain a constant level of water in the boiler. By using an E-pump with level sensor in the boiler, it is possible to maintain a constant water level. A constant water level ensures optimum and costefficient operation as a result of a stable steam production. Dosing applications • Chemical industry, i.e. control of pH values • petrochemical industry • paint industry • degreasing systems • bleaching systems, etc. Example: In the petrochemical industry, E-pumps with pressure sensor are used as dosing pumps. The E-pumps help to ensure that the correct mixture ratio is achieved when more liquids are combined. E-pumps functioning as dosing pumps improve processing and offer energy savings. E-pumps in commercial building services Commercial building services use E-pumps to maintain a constant pressure or a constant temperature based on a variable flow rate. Constant pressure Water supply in high-rise buildings, such as office buildings and hotels. Example: E-pumps with pressure sensor are used for water supply in high-rise buildings to ensure a constant pressure even at the highest draw-off point. As the consumption pattern and thus the pressure changes during the day, the E-pump continuously adapts its performance until the pressure is equalized. Constant temperature • Air-conditioning systems in hotels, schools, etc. • building cooling systems, etc. Example: E-pumps are an excellent choice for buildings where a constant temperature is essential. E-pumps keep the temperature constant in airconditioned, high-rise glass buildings, irrespective of the seasonal fluctuations of the outdoor temperature and various heat impacts inside the building. CRE, CRIE, CRNE Control options Grundfos GO Remote It is possible to communicate with CRE, CRIE, CRNE pumps via the following platforms: • control panel on the pump • Grundfos GO Remote • central management system. The purpose of controlling an E-pump is to monitor and control the pressure, temperature, flow rate and liquid level of the system. The pump is designed for wireless radio or infrared communication with Grundfos GO Remote. Grundfos GO Remote enables the setting of functions and gives access to status overviews, technical product information and actual operating parameters. Grundfos GO Remote offers three different mobile interfaces (MI). Control of E-pumps 3 Control panel on the pump The control panel on the E-pump terminal box makes it possible to change the setpoint settings manually.

Communication is enabled by connecting the E-pump to a central management system. This allows the operator to monitor the pump and to change control modes and setpoint settings. Grundfos CRE, CRIE and CRNE pumps are available in two variants: • CRE, CRIE and CRNE with integrated pressure sensor • CRE, CRIE and CRNE without sensor. CRE, CRIE and CRNE with integrated pressure sensor Central management system Use CRE, CRIE and CRNE pumps with integrated pressure sensor in applications where you want to control the pressure after the pump, irrespective of the flow rate. For further information, see Control of Epumps on page 18. Signals of pressure changes in the pipe system are transmitted continuously from the sensor to the pump. The pump responds to the signals by adjusting its performance up or down to compensate for the pressure difference between the actual and the desired pressure. As this adjustment is a continuous process, a constant pressure is maintained in the pipe system.

Advanced use of MLE motors Introduction Grundfos MLE motors have many features for the advanced user. Grundfos three-phase MLE motors have features such as bearing monitoring, standstill heating, stop function, signal relays, analog sensors and limit exceeded. These features give a unique opportunity to customize the E-pumps. PC Tool E-products gives access to most of the settings available in the products, as well as the possibility of logging and viewing data. All of these features are described below. Bearing monitoring Bearing monitoring is a built-in function indicating the time to relubricate or replace the bearings of the MLE motor. The relubrication feature is only available for three-phase pumps of 15-30 HP. Purpose and benefits The purpose of this function is to give an indication to the user when it is time to relubricate or replace the motor bearings. This is important information for maintenance planning. Bearing monitoring provides these benefits: • The bearing can be relubricated at the right time according to the manufacturer's recommendations. • Maximum life of the motor bearings is obtained. • Maintenance intervals are based on the operating conditions of the bearings. • No worn-down or damaged bearings, and consequently no costly down-time, due to overseen maintenance. Description When the bearing monitoring function determines that it is time to relubricate the bearings, the user will receive a warning via PC Tool E-products, a bus or a relay. When the bearings have been relubricated, a certain number of times, the warning function will inform the user to replace the bearings. The number of relubrications before bearing replacement is set by Grundfos. Technical description The bearing monitoring function is available on two levels for calculating the relubrication interval, basic and advanced: 22 Bearing monitoring function Basic level Calculation of relubrication intervals based on motor revolutions The basic level is a standard feature of the 15-30 HP basic controller and no special functional module is required. Advanced level (only 15-30 HP) Calculation of relubrication intervals based on motor revolutions and bearing temperature Note: The advanced-level function requires the following: • The extended functional module must be fitted in the MLE motor. • Temperature sensors must be fitted at the drive end and at the non-drive end of the motor. Standstill heating Standstill heating is a feature ensuring that even during standstill periods the motor windings have a certain minimum temperature. Purpose and benefits The purpose of this function is to make the MLE motor more suitable for outdoor installation. During standstill periods, there is a need to keep the motor temperature higher than the ambient temperature to avoid condensation in and on the motor. Traditionally this issue has been solved by using an anti-condensation heater on the stator coil heads. Now Grundfos provides this feature by means of a special function within the MLE motor and terminal box. The MLE motor has standstill heating included. An external heater on the stator coil is not necessary. Applications This function is especially suitable in outdoor applications and at installation sites with fluctuating temperatures. Description The working principle is that AC voltage is applied to the motor windings. The applied AC voltage will ensure that sufficient heat is generated to avoid condensation in the motor. The terminal box is kept warm and dry by the heat generated via the power supply. However, it is a condition that the terminal box is not exposed to open air. It must be provided with a suitable cover to protect it from rain. CRE, CRIE, CRNE Outdoor installation Advanced use of MLE motors 4 Diaphragm tank Stop function Pressure sensor Pump TM03 8583 1907 According to UL 778 and C22.2 No 108-14, pumps that are intended for outdoor use must be marked enclosure type 3, and the product must be tested at a rated surface temperature down to -31 °F (-35 °C). The MLE enclosure is approved for type 3 or 4 and a rated surface temperature down to 32 °F (0 °C), and thus only for indoor use in UL 778 and C22.2 No 108-14 pump applications. See the installation and operating instructions for additional details. Check valve Fig. 22 Position of the check valve and pressure sensor in system with positive inlet pressure When low flow is detected, the pump is in start/stop operation. If there is flow, the pump will continue operating according to the setpoint. See fig. 23. The stop function ensures that the pump is stopped at low or no flow. The function is also called low-flow stop function. Start/stop operation Continuous operation Stop pressure Purpose and benefits The purpose of the stop function is to stop the pump when low flow is detected. The stop function provides these benefits: • The energy consumption is optimized and the system efficiency is improved. • Unnecessary heating of the pumped liquid which damages pumps is avoided? • Wear of the shaft seals is reduced. • Noise from operation is reduced. ∆H Fig. 23 Constant pressure with stop function. Difference between start and stop pressures (∆H) Applications The stop function is used in systems with periodically low or no consumption thus preventing the pump from running against closed valve. Operating conditions for the stop function A pressure sensor, a check valve, and a diaphragm tank are required for the stop function to operate properly. Note: The check valve must always be installed before the pressure sensor. See fig. 21 and fig. 22. Diaphragm tank Check valve TM03 8582 1907 Pressure sensor Pump TM03 8477 1607 Start pressure Fig. 21 Position of the check valve and pressure sensor in system with suction lift operation Diaphragm tank The stop function requires a diaphragm tank of a certain minimum size. The tank must be installed near the pump outlet, and the precharge air pressure must be 0.7 x setpoint. Recommended diaphragm tank size: Rated flow rate of pump [gpm (m3h)] CRE pump Typical diaphragm tank size [gal (liter)] 0-26 (0 - 5.9) 1s, 1, 3 2 (7.6) 27-105 (6.1 - 23.8) 5, 10, 15 4.4 (16.7) 106-176 (24.2 - 40) 20, 32 14 (53.0) 177-308 (40.2 - 70.0) 45 34 (128.7) 309-440 (70.2 - 99.9) 64, 90 62 (234.7) 441-750 (100-170) 120, 150 86 (325.5) If a diaphragm tank of the above size is installed in the system, additional adjustment is unnecessary. If the tank installed is too small, the pump will start and stop often. Tank size will influence at which flow rate the system will go into start/stop operation. Description The low-flow stop function can operate in two different ways: • by means of an integrated low-flow detection function • by means of an external flow switch connected to the digital input. 23 CRE, CRIE, CRNE 4 Advanced use of MLE motors Low-flow detection function Purpose and benefits • The low-flow detection function will check the flow rate regularly by reducing the speed for a short time. A small change in pressure or no change in pressure means that there is low flow. The temperature sensor inputs 1 and 2 provide these benefits: • The temperature sensor inputs can be used as input to the limit exceeded functions 1 and 2. • In combination with the bearing monitoring function, the temperature sensors provide optimum monitoring of the motor bearings. • A bearing warning or a bearing alarm can be indicated as the motor bearing temperature is measured. • Status readings of the measured temperatures are available via Grundfos GO, PC Tool E-products and a bus. • The function has a built-in signal fault detection if the temperature sensors fail or a conductor is broken. Low-flow detection with flow switch • When a flow switch detects low flow, the digital input will be activated. Contact Grundfos for further information. Dry-running protection This function protects the pump against dry running. When lack of inlet pressure or water shortage is detected, the pump will be stopped before being damaged. Lack of inlet pressure or water shortage can be detected with a switch connected to a digital input configured to dry-running protection. The use of a digital input requires an accessory, such as: • a Grundfos Liqtec® dry-running switch (for more information on LiqTec, see Accessories on page 90) • a pressure switch installed on the inlet side of the pump • a float switch installed on the inlet side of the pump. The pump cannot restart as long as the digital input is activated. Temperature sensors 1 and 2 One or two Pt100 temperatures sensors may be connected to the input terminals 17, 18, 19, and 20. 17: 18: 19: 20: Pt100 Pt100 Pt100 Pt100 A A B B TM03 9191 3507 Extended module Fig. 24 Temperature sensor connections in the extended functional module 24 Applications The temperature inputs can be used in all applications where temperatures in the system or in the motor need to be monitored. Note: The temperature sensor inputs are available on all MLE motors. Description The temperature sensor inputs enable several functions. • The temperature sensor inputs 1 and 2 can be used as input to the limit exceeded functions 1 and 2. If a limit is exceeded, this will be indicated. The indication will be in the form of outputs (relay) or alarms/warnings set or defined in the limit exceeded functions 1 and 2. • The temperature sensor inputs 1 and 2 can be set to measure bearing temperature. The measured values of temperature sensor 1 and 2 are used in the calculation of relubrication intervals. Additionally, the measured value can activate the indication of a bearing warning or a bearing alarm. In case of high bearing temperature, a warning or an alarm can be logged and force the pump to stop. CRE, CRIE, CRNE Signal relays Analog sensor inputs 1 and 2 Signal relays are used to give an output indication of the current operational status of the MLE. The signal relay is a potential free contact (also called a dry contact). The output signals are typically transmitted to external control systems. The analog sensor inputs 1 and 2 are standardized inputs for measuring all types of analog parameters. Sensor input 1 is the only sensor input set for closedloop operation. The input will be used as the sensor feedback input. Sensor input 2 is referred to as the secondary sensor. Purpose and benefits The signal relays offer these features: • The signal relays can be remotely (via bus) or internally controlled. • The signal relays can be set to indicate several types of operational status. • A relay delay can be defined to avoid activating the relay in case of periodic failures. Extension module Advanced use of MLE motors 4 16: GND 15: + 24 V 14: Sensor input 2 9: GND 8: + 24 V 7: Sensor input 1 Applications Signal relays can be used in all applications involving a need to read out the operational status to e.g. a control room or to a superior control system. The signal relays can be set with these three parameters: • relay control • relay setup • relay delay. TM03 9214 3607 Description Fig. 27 Sensor inputs 1 and 2 connections Purpose and benefits Fig. 25 Signal relay parameters for 1/2 - 10 HP pumps Fig. 26 Signal relay parameters for 15-30 HP pumps The analog sensor inputs 1 and 2 provide these benefits: • Sensor input 1 can be feedback input for the built-in PI controller. • It is possible to monitor secondary parameters in the process, e.g. flow rate or liquid temperature. • The secondary sensor can be set as a redundant sensor. • The sensors can give input to the limit exceeded functions 1 and 2. • Status readings of the inputs are available via Grundfos GO and PC Tool E-products. Relay control Applications The relay time is 0 seconds and the signal relay is internally controlled. The advanced relay control can only be set via PC Tool E-products. Relay control has these two setting options: • Internally controlled The relay is internally controlled by the variable frequency drive software according to the setup of the relay [Ready, Fault, Operation]. • Remotely controlled The relay is controlled via commands from the GENIbus. Analog sensor inputs 1 and 2 can be used in applications with a need for monitoring essential parameters. 25 CRE, CRIE, CRNE 4 The analog sensors 1 and 2 enable several functions. • When the secondary sensor is set as an input to the limit exceeded functions 1 and 2, defined outputs or warnings or alarms can be given when system parameters are outside defined system limits. • Connecting a flow sensor. When sensor input 2 is set with a flow sensor, the measured value can be used as input to the proportional-pressure function. The flow rate displayed in Grundfos GO will be the measured flow rate instead of the estimated flow rate. The flow rate measurement can also be used in the low-flow stop function to detect low flow instead of estimating the flow rate by lowering the speed of the pump. • Sensor reading via Grundfos GO and PC Tool Eproducts. When sensors are set, the user can get a status reading via Grundfos GO and PC Tool E-products. Analog output Analog output The analog output (0-10 mA) can be set via PC Tool Eproducts to one of these indications: • feedback value • speed • frequency • motor current • external setpoint input • limit exceeded. The analog output is default set to not active. Feedback value The output signal is a function of the actual feedback sensor. Speed The output signal is a function of the actual pump speed. Frequency The output signal is a function of the actual frequency. Motor current The output signal is a function of the actual motor current. External setpoint input The output signal is a function of the external setpoint input. Limit exceeded The output signal indicates whether the limit is exceeded: • Minimum output = limit is not exceeded. • Maximum output = limit is exceeded. 26 Limit exceeded 1 and 2 Limit exceeded is a monitoring function monitoring one or two values or inputs. The function enables different inputs to activate various outputs and alarms/ warnings when the signal input has exceeded predetermined limits. Outputs Input Limit exceeded Alarm/ warning TM03 9188 3507 Advanced use of MLE motors Description Fig. 28 Example of a limit exceeded sequence Purpose and benefits The purpose of this function is to monitor parameters which are central for the application. This will enable the controller to react to possible, abnormal operating conditions. This makes the E-pump a more important and integrated part of a system, and it can thus replace other existing monitoring units. The liquid temperature can be monitored, and thus the E-pump can ensure that the system temperature does not exceed a maximum permissible level. The minimum inlet pressure can be monitored, and thus the E-pump can prevent damage caused by a cavitation or dry run. Applications The limit exceeded function is typically used for monitoring secondary parameters in the systems. CRE, CRIE, CRNE Description Pump operating at power limit The figures below show two examples of setpoint monitoring by means of the limit exceeded function. When a pump is operating at the power limit, the MLE motor will deliver an output corresponding to the maximum load stated on the nameplate. The maximum load will never be exceeded. See fig. 31. Monitored value = feedback value Reset hysteresis Advanced use of MLE motors 4 H Power limit Power limit Limit Standard Standard Not active Detection delay Active Reset delay Fig. 29 Limit exceeded sequence with the limit type "max. limit", for example monitoring of bearing temperature Monitored value = feedback value Reset hysteresis Setpoint Action Not active Detection delay Active Reset delay TM03 9196 3607 Limit Fig. 30 Limit exceeded sequence with the limit type "min. limit" P2 Q TM05 2357 4911 Action TM03 9197 3607 Setpoint Fig. 31 Curves of a standard E-pump and a pump operating at power limit Purpose and benefits When using a standard pump at a low flow rate, the power consumption will drop and the motor will have excess power available. By setting the CRE pump to operate at a higher speed, the excess power can be used to provide a higher pressure. The power limit function will make sure that the motor load never exceeds its maximum by decreasing the speed until the motor is at its power limit. In cases where an undersized motor is used with standard speed, the power limit function will still reduce the speed and protect the motor against overload at a high flow rate. The solution offers the following benefits: • reduced motor size • reduced pump size. When the limit is exceeded, the signal input crosses the limit as an increasing or decreasing value, and the function can be set to cover both situations. 27 CRE, CRIE, CRNE 4 Advanced use of MLE motors Figure 32 shows that a pump operating at low flow rates and relatively high pressures (1) can be fitted with an undersize motor with a rated power that matches this operating range. At higher flow rates and relatively lower pressures (2), the motor will reduce its speed when the power limit is exceeded and follow a steeper curve corresponding to the power available. H ----------- Undersize motor _______ Standard motor Applications The power limit function is primarily used in applications where the motor size is dimensioned to be as small as possible to reduce size or cost. It is also used in applications demanding a high maximum speed to achieve a high pressure at a low flow rate. In both cases, the motor is protected by the power limit function at a higher flow rate where a lower speed is needed to prevent the motor from overloading. Examples of applications: • Washing and cleaning • Boiler feed. P2 1 TM05 2359 4911 Setup 2 Q Fig. 32 Standard performance curve compared to a curve for a pump fitted with an undersize MLE motor. The MLE motor can be set to a higher speed than a standard motor, enabling the pump to deliver more pressure. The pump will operate at this higher speed until the pump reaches the flow rate where the motor is loaded to its full rated power. If the flow rate is increased further, the motor will reduce its speed so as not to exceed its rated power. Using this function can, in some instances, enable the use of a smaller pump to reach the desired duty point compared to a pump running with standard maximum speed. See fig. 33. The power limit is always active in CRE pumps to protect the motor against overload. Pumps with undersize motor and pumps with higher maximum speed are available as factory-configured products. Note: Running the pump at over-synchronous speed will affect the NPSH value, thus requiring a sufficient inlet pressure to avoid cavitation. The sound pressure level emitted from the pump and motor may increase at higher speeds. Furthermore, the differential pressure over the chambers must be taken into consideration. Stabilizing unstable pump curves When the pump curve has a shape where it intersects the system curve in two points (A and B) with identical pressure but at different flow rates, the pump curve is defined as unstable. See fig. 34. This is especially problematic in systems with a flat system characteristic as it prevents the pump from being controlled to a flow rate which is lower than the flow rate at point B. H ----------- Maximum speed _______ Standard speed Counter pressure A B Flat system characteristic Q Fig. 33 Standard performance curve (60 Hz) compared to a performance curve for a pump running at maximum speed. 28 TM06 9673 0717 P2 TM05 3314 5111 Unstable curve Fig. 34 Unstable pump curve CRE, CRIE, CRNE 4 Advanced use of MLE motors The E-motor can stabilize an unstable pump curve in the low-flow area by changing to a higher speed. Figure 35 illustrates how the pump curve is straightened out in this area. As the flow rate increases, the E-motor gradually reduces the speed to normal speed and the pump performance will follow the standard pump curve. Stabilized pump curve TM06 9671 0717 Unstable standard pump curve Fig. 35 Pump curve with a stabilized operating range Purpose and benefits The purpose of stabilizing an unstable pump is to enable normal control throughout the entire operating range. Thus fully stable operation is achieved, even in the low-flow range. This enables the use of modern high-efficiency pumps in applications where this would otherwise not be possible. Applications As mentioned, unstable operation may occur in applications with a high counter pressure and a flat system characteristic. Examples of applications: • pumping of water to a water tower • boiler feed. Note: The sound pressure level emitted from the pump and motor may increase at higher speeds. Setup This function is available in factory-configured products. 29 CRE, CRIE, CRNE 5 Application examples of differential pressure in a 5. Application examples of differential pressure in a circulation system Circulation systems (closed systems) are well-suited for speed-controlled pump solutions. It is an advantage that circulation systems with variable system characteristic are fitted with a differential-pressure-controlled circulator pump. See fig. 36.

Differential-pressure transmitter Proportional differential pressure TM03 0409 5004 The differential pressure of the pump is reduced at falling flow rate and increased at rising flow rate. See fig. 38. Figure 36 shows a heating system consisting of a heat exchanger where the circulated water is heated and delivered to three radiators by a speed-controlled pump. A control valve is connected in series at each radiator to control the flow rate according to the heat requirement. The pump is controlled according to a constant differential pressure measured across the pump. This means that the pump system offers constant differential pressure in the Q range of 0 to Qmax., represented by the horizontal line in fig. 36. 30 Qmax. TM03 8475 1607 Fig. 36 Constant differential-pressure control Fig. 38 Proportional differential pressure The pump is controlled according to a differential pressure measured across the pump.

The proportional differential pressure can be selected with one of these flow dependencies: • linear (setting via PC Tool). • parabolic (setting via PC Tool). When the flow dependency is selected as parabolic, the differential pressure of the pump will be reduced with a parabolic curve at falling flow rate and increased at rising flow rate. See fig. 39. TM06 2479 1014 The setpoint range is between 25 % to 90 % of maximum head.

See the following examples: Example 1: Pump: CRE 3-10 A-A-A Maximum operating pressure:232 psi Maximum inlet pressure: 145 psi Outlet pressure against a closed valve: 139.2 psi, see page 48. This pump must not start at an inlet pressure of 145 psi, but at an inlet pressure of 232.0 - 139.2 = 92.8 psi. Example 2: Pump: CRE 10-2 A-GJ-A Maximum operating pressure: 232 psi Maximum inlet pressure: 116 psi Outlet pressure against a closed valve: 42 psi (97 ft), see page 56. This pump may start at an inlet pressure of 116 psi, as the outlet pressure is only 42 psi, which results in an operating pressure of 116 + 42 = 158 psi. On the contrary, the maximum operating pressure of this pump is limited to 158 psi, as a higher operating pressure will require an inlet pressure of more than 116 psi. In case the inlet or operating pressure exceeds the pressure permitted, see Lists of variants on request on page 107. CRE, CRIE, CRNE 9 Selection and sizing 9. Selection and sizing Selection of pump Selection of pump must be based on the following information • the duty point of the pump, see section 1 below • sizing data such as pressure loss as a result of height differences, friction loss in the pipes, pump efficiency etc., see section 2 below • pump materials, see section 3 below • pump connections, see section 4 below • The shaft seal, see section 5 below.

The head (H), the flow rate (Q) and the input power (P) are all the appropriate variables for determining the motor speed (n). See fig. 51. 40 Q TM00 8720 3496 Selection and sizing Normally, E-pumps are used in applications characterized by a variable flow rate. Consequently, it is not possible to select a pump that is constantly operating at its best efficiency. In order to achieve optimum operating economy, select the pump on the basis of the following criteria: • The maximum required duty point must be as close as possible to the QH curve of the pump. • The required duty point must be positioned so that P2 is close to the maximum point of the 100 % curve. Between the minimum and maximum performance curve E-pumps have an infinite number of performance curves each representing a specific speed. Therefore it may not be possible to select a duty point close to the 100 % curve.

The power equation implies that the pump efficiency is unchanged at the two speeds. In practice this is not quite correct. Finally, it is worth noting that the efficiencies of the frequency converter and the motor must be taken into account if a precise calculation of the power saving resulting from a reduction of the pump speed is wanted. Grundfos Product Center We recommend that you size your pump in Grundfos Product Center, which is a selection program offered by Grundfos. For further information, see Grundfos Product Center. Grundfos Product Center features a user-friendly and easy-to-use virtual guide which leads you through the selection of the pump for the application in question. CRE, CRIE, CRNE 6.

The following three key parameters must be taken into account, when selecting the shaft seal: • type of pumped liquid • liquid temperature • maximum pressure. Grundfos offers a wide range of shaft seal variants to meet specific demands. See List of pumped liquids on page 87. TM02 1201 0601 Selection of pump connection depends on the rated pressure and the pipes. To meet any requirement, the CRE, CRIE and CRNE pumps offer a wide range of flexible connections such as: • oval flange (NPT), fig. 53 • ANSI flange, fig. 53 • PJE coupling, fig. 53 • clamp coupling • union (NPT[M]) • other connections on request. Selection and sizing 9 Fig. 54 Shaft seal (cartridge type) 41 CRE, CRIE, CRNE 9 We recommend that you calculate the inlet pressure "H" in these situations: • The liquid temperature is high. • The flow rate is significantly higher than the rated flow rate. • Water is drawn from depths. • Water is drawn through long pipes. • Inlet conditions are poor. To avoid cavitation, make sure that there is a minimum pressure on the inlet side of the pump. The maximum suction lift "H" in feet can be calculated as follows: H Pb tm (°F) Hf H Pb NPSHR Hv Hv = Vapor pressure in feet. (To be read from the vapor pressure scale. "Hv" depends on the liquid temperature "Tm"). Hs = Safety margin = minimum 2.0 feet. If the "H" calculated is positive, the pump can operate at a suction lift of maximum "H" feet. If the "H" calculated is negative, an inlet pressure of minimum "H" feet is required. 42 360 328 340 259 320 203 300 148 131 115 98 270 82 250 66 230 49 212 39 33 26 194 = pb - NPSHR - Hf - Hv - Hs. = Barometric pressure in feet absolute.

The liquid must not chemically attack the pump materials. When pumping liquids with a density and/or viscosity higher than that of water, oversized motors must be used. Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are the chloride content, pH value, temperature and content of chemicals, oils, etc. Please note that aggressive liquids, such as sea water and some acids, may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion. The CRE, CRIE, CRNE pump types are suitable for the following liquids: CRE, CRIE • Non-corrosive liquids. For liquid transfer, circulation and pressure boosting of cold or hot clean water. List of pumped liquids A number of typical liquids are listed on the following pages. Other pump versions may be applicable, but those stated in the list are considered to be the best choices. The table is intended as a general guide only, and cannot replace actual testing of the pumped liquids and pump materials under specific working conditions. The list should, however, be applied with some caution as factors such as the following may affect the chemical resistance of a specific pump version: • concentration of the pumped liquid • liquid temperature • pressure. Safety precautions must be made when pumping dangerous liquids. Notes CRNE D Industrial liquids in systems where all parts in contact with the liquid must be made of high-grade stainless steel. E CRTE • Saline liquids • hypochlorites • acids. For saline or chloride-containing liquids, such as sea water or oxidizing agents such as hypochlorites, CRTE pumps of titanium are available. See separate product guide on CRT, CRTE. Pumped liquids 12. Pumped liquids F Often with additives. Density and/or viscosity differ from that of water. Allow for this when calculating motor output and pump performance. Pump selection depends on many factors. Contact Grundfos.

CRE, CRIE, CRNE 14 Lists of variants on request Although the Grundfos CR, CRE, CRI, CRIE, CRN, CRNE product range offers a number of pumps for different applications, customers require specific pump solutions to satisfy their needs. Below please find the range of options available for customizing the CR, CRE pumps to meet the customers' demands. Contact Grundfos for further information or for requests other than the ones mentioned below. Motors Variant Description Explosion proof motors For operation in hazardous atmospheres, explosion-proof or dust-ignition-proof motors may be required. Motors with anticondensation heating unit For operation in humid environments motors with built-in anti-condensation heating may be required. Premium efficient motors Grundfos offers motors from 1 to 100 HP with a Premium efficiency class. Different motor brand Oversized motor 4-pole motors If technically possible, Grundfos can fit the pump with a motor of a brand other than the standard. This will normally increase the time of delivery. Alternatively, the pump can be supplied without a motor (motor thrust rating must be checked). Ambient temperatures above 104 °F (40 °C) or installation at altitudes of more than 3280 ft above sea level require the use of an oversized motor (i.e. derating). Grundfos offers standard motors fitted with 4-poles. Shaft seals Variant Description Shaft seal with We recommend shaft seals with FFKM or FXM Oring material for applications where the pumped FFKM O-ring liquid may damage the standard O-ring material. material Seal with flush, Recommended for applications involving quench seal crystallizing, hardening or sticky liquids. Recommended for applications involving extremely high temperatures. No conventional mechanical shaft seal can withstand liquid temperatures of up to 356 °F for ® Cool-Top any length of time. shaft seal For that type of application, we recommend system Grundfos' unique air-cooled shaft seal system. In order to ensure a low liquid temperature around the standard shaft seal, the pump is fitted with a special air-cooled shaft seal chamber. No separate cooling is required. Recommended for applications involving poisonous or explosive liquids. Protects the surrounding environment and the Double shaft people working in the vicinity of the pump. seal with Consists of two seals mounted in a "back-to-back" pressure arrangement inside a separate pressure seal chamber chamber. As the pressure in the chamber is higher than the pump pressure, leakage is prevented. A dosing pump or a special pressure-intensifier generates the seal chamber pressure. Magnetically driven pumps for industrial applications. Key applications are industrial processes involving CRN MAGdrive the handling of aggressive, environmental, dangerous or volatile liquids, e.g. organic compounds, solvents, etc. Pumps Variant Connections and other variants Variant Horizontally mounted pump Description In addition to the wide range of standard flange connections, a 232 psi DIN standard Pipe connections clamping flange is available. Customized flanges are available according to specifications. TriClamp connections are of a hygienic TriClamp connections design with a sanitary coupling for use in the pharmaceutical and food industry. Electropolishing substantially reduces the Electropolished risk of corrosion of the materials. pumps Electropolishing is used in the pharmaceutical/food industry. Variants 14. Variants Low-temperature pump to -4 °F High-speed pump up to 681 psi High-pressure pump up to 696 psi Low-NPSH pump (improved suction) Belt-driven pumps Pumps for pharmaceutical and biotechnological applications Description For safety or height reasons, certain applications, for instance on ships, require the pump to be mounted in the horizontal position. For easy installation the pump is equipped with brackets that support motor and pump. Exposed to temperatures down to -40 °F (-40 °C) coolant pumps may require neck-rings with a different diameter in order to prevent impeller drag. For high-pressure applications, a unique pump capable of generating up to 681 psi (47 bar) pressure is available. The pump is equipped with a high-speed motor, type MLE. The direction of rotation is the opposite of that of standard pumps, and the chamber stack is turned upside-down, as a result of which the pumped liquid flows in the opposite direction. For high-pressure applications, a unique double pump system capable of generating up to 696 psi (48 bar) pressure is available. Recommended for boiler-feed applications where cavitation may occur due to poor inlet conditions. Belt-driven pumps designed to operate in places with limited space or where no electrical power is available.
