Features and benefits SQ, SQE pumps offer these features: • • • • • • • Dry-run protection high efficiency pump and motor protection against up-thrust soft-start over-voltage and under-voltage protection over-temperature protection high starting torque. Product introduction 1. Product introduction The "Smart Motor" communicates via the CU301 status box through the power leads. It is not necessary to run any additional wires down the well. Communication with the pump provides Constant Pressure Control and the highly useful ability to change the pump performance while the pump is installed in the well. Like the SQ motor, this is also a 2wire motor designed for single-phase operation. Dry-running protection The pumps are protected against dry running. A value of Pcut-out ensures cut-out of the pump in case of lack of water in the borehole thus preventing a burnout of the motor. Pcut-out is factory-set both for the SQ and SQE, SQENE pumps. H Q • Constant pressure control • variable speed • electronic control and communication. P P1 P cut-out cut-out Q SQ, SQE pumps feature an innovative motor design incorporating permanent-magnet technology. By combining permanent-magnet motors and a Grundfos micro-frequency converter, we are able to deliver unmatched performance and the ability to control and communicate with the pump in ways never before possible. A few of the features that result from this combined technology are Constant Pressure Control, Soft-Start, and Integrated Dry-Run Protection, but these are just a few of the features these pumps offer. SQ pump models operate at a constant speed much like today’s conventional pumps. The difference is that SQ delivers the benefits of an electronically controlled permanent-magnet motor that cannot be achieved with a conventional induction motor. Fig. 1 Pcut-out curve High pump efficiency The hydraulic pump components are polyamide reinforced with 30 % glass fiber. The hydraulic design provides for high pump efficiency resulting in low energy consumption and therefore low energy costs. High motor efficiency The motors are based on a permanent magnet rotor (PM motor) featuring high efficiency within a wide load range. Eta [%] 70 SQ.3 MS 65 Conventional Conventional3-ph. 3 ph SQ pumps are available for single-phase power; a simple 2-wire design makes installation easy. 60 Conventional Conventional1-ph. 1 ph SQE pumps are equipped with a Grundfos "Smart Motor." Like the SQ models, SQ pumps have a high efficiency permanent-magnet motor — but we add the ability to communicate. 50 55 45 200 Fig. 2 250 300 350 400 450 500 550 P2 [W] TM01 2698 2298 SQ, SQE innovative motor technology TM01 2751 2298 Additionally, SQE pumps offer these advantages: Efficiency curves of Grundfos SQ motor versus conventional motors 3 SQ, SQE, SQE-NE, CU331SP 1 Overvoltage and undervoltage protection The pump design features "floating" impellers (not fastened to the shaft). Each impeller has its own tungsten carbide/ceramic bearing. The construction and materials ensure high wear resistance to sand for long product life. Overvoltage and undervoltage may occur in case of unstable voltage supply. TM01 3141 3498 Product introduction Wear resistance Fig. 3 The pump will cut out if the voltage falls below 150 V or rises above 315 V. The motor is automatically cut in again when the voltage again falls within the permissible voltage range. Therefore no extra protection relay is needed. Overload protection Example of Grundfos floating impeller Protection against upthrust Starting up a pump with a very low counter pressure involves the risk of the entire impeller stack being lifted, also called upthrust. Upthrust may cause breakdown of both pump and motor. SQ, SQE, SQE-NE motors are fitted with a top bearing protecting both pump and motor against upthrust, thus preventing breakdown during the critical start-up phase. Excellent starting capabilities The integrated electronic unit of the motor features soft starting. Soft start reduces the starting current and thus gives the pump a smooth and steady acceleration. The soft starter minimizes the risk of wear on the pump and prevents overloading of the mains during start-up. The excellent starting capabilities are a result of the high locked-rotor torque of the permanent magnet motor together with the few pump stages. The high starting reliability also applies in case of low voltage supply. Exposure of the pump to heavy load causes the current consumption to rise. The motor will automatically compensate for this by reducing the speed to 3000 rpm. Further overload will lead to stop. If the rotor is being prevented from rotating, this will automatically be detected and the power supply will be cut out. Consequently, no extra motor protection is needed. Overtemperature protection A permanent magnet motor gives off very little heat to its surroundings. In combination with an efficient internal circulation system leading the heat away from the rotor, stator and bearings, this ensures optimum operating conditions for the motor. As an extra protection, the electronic unit has a built-in temperature sensor. When the temperature rises too high, the motor is cut out; when the temperature has dropped, the motor is automatically cut in again. Reliability The motors are built for high reliability and feature: • Tungsten carbide / ceramic bearings • thrust bearings protecting against downthrust Current [A] • product life time equal to conventional AC motors. Variable speed Soft start 3 Soft-start feature Time [s] TM01 3479 4198 DOL (direct-on-line starting) Fig. 4 The integrated protection of all motors prevents damage to the motor in case the voltage moves outside the permissible voltage range. The SQE motor enables continuously variable speed control from 3,000 to 10,700 rpm. The pump can be set to operate in any duty point in the range between the 3,000 and 10,700 rpm performance curves of the pump. Consequently, the pump performance can be adapted to any specific requirement. The variable speed control facility requires the use of the CU 300 or CU 301 control unit. For the calculation of pump speed, the program "SQE Speed Calculation" is available on CD-ROM as an accessory. 4 SQ, SQE, SQE-NE, CU331SP 1 Product introduction Identification Type key example SQ, SQE, SQE-NE 10 SQ E 05 - 160 N E Rated gallons per minute Basic version (without communication) Electronic communication Horsepower Total Dynamic Head in (ft) at rated flow Stainless steel 316 Environmental, PVDF impellers 5 SQ, SQE, SQE-NE, CU331SP 2 Applications 2.

The pump will run until the pressure is 7 psi (0.5 bar) above setpoint. This way of operation is called on/off operation. The system maintains a constant pressure within the maximum pump performance in spite of a varying water consumption. The pressure is registered by the pressure sensor and transmitted to the CU 301. The CU 301 adjusts the pump performance accordingly. At a flow higher than approximately 1 gpm (0.18 m3/h), the pressure will drop quickly and the pump will start immediately and maintain a constant pressure. Function When a tap is opened the pressure in the tank will start to drop. At a flow lower than approximately 1 gpm (0.18 m3/h), the pressure will drop slowly. During operation, the CU 301 will regulate the pump speed to maintain a constant pressure. If there is no consumption, the pump will boost the pressure to 7 psi (0.5 bar) above setpoint and stop after a few seconds. 1 2 3 4 5 10 14 18 21 22 30 31 Pump, SQE Cable Cable clips Pressure tank, 2 gal (8 liters) Control unit, CU 301 Pressure sensor, 0 - 120 psi (0 - 6 bar) Pressure gauge Tap Mains connection Riser pipe Safety cable Wire clamp TM03 3429 0406 Recommended min. 20 inches (0.5 m) Min. 20 inches (0.5 m) Fig. 6 Application example: Constant-pressure control with CU 301 - residential water supply Pos.

Dry-running protection The software program "SQE Speed Calculation" has been developed for the calculation of the speed in order to obtain the required flow rate and head. If the speed of the SQE pump is reduced by more than 1000 rpm, the Pcut-out value must be readjusted by means of the CU 300 and R100. The value Pcut-out, ensuring dry-running protection, is factory-set for the SQE pump. CU 300 R100 Note: The SQE pump must not be started until the pump has been completely submerged below the water table. However, the change of the motor speed can be made even if the pump is not submerged.

This application is especially suitable for sampling from groundwater monitoring wells. The monitoring well is purged at high speed and the sample is taken at a low speed (quiet flow). For contaminated groundwater the SQE-NE type range is recommended. In case frequent sampling is required, dedicated installation of the pump is recommended, thus eliminating wear caused by frequent assembly and dismantling the installation. 5 Applications SQE with manual speed control Furthermore, dedicated installations saves the costs of assembling and dismantling the installation. Important: Through dedicated installation the transfer of contamination from one monitoring well to another is avoided. Dry-running protection The value Pcut out, ensuring dry-running protection, is factory-set for the SQE pump. If the speed of the pump is reduced more than 1,000 rpm, the value of Pcut out must be readjusted by means of CU 300 and R100. 1 2 3 5 21 22 30 31 32 32 21 SQE pump Cable Cable clips Control unit, CU 300 Mains connection Riser pipe Stainless-steel safety cable Stainless-steel wire clamps, 2 per lifting eye Potentiometer, SPP 1 22 Recommended min. 20 inches (0.5 m) 2 3 30 31 TM01 9028 4801 1 Min. 20 inches (0.5 m) Fig. 12 Application example: Sampling/manual speed control of SQE Pos. 1 2 3 5 22 30 31 32 Part Type Pump Cable Cable clips Control unit Riser pipe Stainless-steel safety cable Wire clamps Potentiometer SQE No. of units Product number Unit price Total price CU 300 2 per lifting eye SPP 1 13 SQ, SQE, SQE-NE, CU331SP 3 Performance range 3.

Installation The SQ and SQE, SQE-NE may be installed vertically, horizontally or in any position in between. Note: The pump must not fall below the horizontal level in relation to the motor. The following features ensure simple installation of the pump: • Built-in check valve with spring • low weight ensuring user-friendly handling • installation in 3" or larger boreholes • only on/off switch is needed, which means that no extra motor starter / starter box is necessary. For horizontal installation a flow sleeve is recommended in order to: • ensure sufficient flow velocity past the motor and thus provide sufficient cooling • prevent motor and electronic unit from being buried in sand or mud.

R100 makes it possible to reduce the pump speed by changing the setpoint. The speed can be set to 3,000 - 10,700 rpm, at 100 rpm intervals. The unit of the setpoint is automatically changed according to the unit of the sensor connected to sensor input 1. Example: Sensor input 1 is connected to a pressure sensor using the unit feet (ft) and the range 0-60. Consequently, the setpoint of display 1.1 can be set to between 0-60 ft. 2.6 The number of operating hours and the number of starts are values accumulated from the time of installation and they cannot be reset. Both values are stored in the motor electronics, and they are kept even if the CU 300 is replaced. The number of operating hours is registered every two hours of continuous operation.

SQ, SQE, SQE-NE, CU331SP 11 Features User interface The user interface offers these possibilities: • Local operation via a control panel with graphic display where the menu structure is based on the well-known system from Grundfos E-pumps. • Monitoring of operating status via indicator lights and signal relays. • Display of alarm or warning and logging of the last five alarms and warnings. Functions Control mode: Constant pressure The CU331SP has only one control mode, Constant pressure. The pressure is kept constant, independently of the flow rate. CU331SP variable frequency drive 11. CU331SP variable frequency drive Applications For 4" or larger wells. Main applications: • • • • Domestic and light commercial water supply irrigation livestock watering water transfer. System components • Compact, efficient, and reliable variable frequency drive • rugged stainless steel pump end and proven, reliable, 3-phase motor • pressure sensor • diaphragm tank (sold separately). Start-up guide TM05 5801 4012 The CU331SP has a start-up guide, which is launched at the first power up. Parameters are set manually on the basis of the installation. The start-up guide can be repeated, if necessary. Thanks to the start-up guide, the installer can quickly set a few parameters and put the CU331SP into operation. Direction of rotation test During start-up, the CU331SP automatically tests and sets the correct direction of rotation without changing the cable connections. The direction of rotation test can be performed manually if it fails for any reason. Fig. 21 CU331SP variable frequency drive and sensor Dry-running protection To protect the pump, the CU331SP will automatically set up dry-run protection so that water shortage can be detected. The dry-run alarm will automatically reset 30 minutes after the alarm is declared. Low-flow stop function The low-flow stop function is used for changing between on/off operation at low flow rate and continuous operation at high flow rate. The low-flow stop function protects the pump and saves energy. 37 SQ, SQE, SQE-NE, CU331SP 11 CU331SP variable frequency drive Identification Nameplate TM05 6001 4012 The CU331SP can be identified by means of the nameplate.

The operating modes can be set without changing the setpoint setting. The outlet pressure is kept constant at high flow rate (Q > Qmin). On/off operation at low flow rate. See fig. 25. Hset Normal The pump operates in constant pressure mode. Qmin Stop The pump has been stopped by user. Fig. 25 Constant pressure with stop function Min. curve The pump is running at a set minimum speed value. See fig. 24. For instance, this operating mode can be used during periods with a very small flow requirement. Max. curve The setpoint can be set or changed during operation using the setpoint display in the "OPERATION" menu shown below. It is not necessary to run the start guide to change the setpoint. TM03 8813 2507 Max. Fig. 24 Min. and max. curves Control mode The CU331SP has been developed specifically to operate submersible pumps in Constant Pressure mode. This Closed-Loop control mode uses an analog pressure transducer to provide pressure feedback to the drive. 42 The pump is controlled according to a constant pressure measured after the pump.This means that the pump offers a constant pressure in the Q-range of Qmin to Qmax, represented by the horizontal line in the QH diagram. Setting the setpoint by means of the OPERATION menu The pump is running at a set maximum speed value. Min. Qmax TM03 8807 3307 CU331SP TM03 8477 2507 CU331SP variable frequency drive Operating modes Low flow and stop functions The pump will check the flow regularly by reducing the speed for a short time. If there is no or only a small change in pressure, this means that there is low flow. The speed will be increased until the stop pressure (actual setpoint + 0.5 x ΔH) is reached and the pump will stop after a few moments. The pump will restart at the latest when the pressure has fallen to the start pressure (actual setpoint - 0.5 x ΔH). SQ, SQE, SQE-NE, CU331SP 11 Operating conditions for the stop function It is only possible to use the stop function if the system incorporates a pressure sensor, a non-return valve and a diaphragm tank. The non-return valve must always be installed before the pressure sensor. Diaphragm tank Pressure sensor CU331SP variable frequency drive Automatic setting The CU331SP automatically tests and sets the correct direction of rotation without changing the cable connections. Automatic setting requires a sensor. This test is not suitable for all pump types and will in certain cases not be able to determine for certainty the correct direction of rotation. In these cases, the CU331SP changes over to manual setting where the direction of rotation is determined on the basis of the installer’s observations. Manual setting when the direction of rotation is not visible The correct direction of rotation is set manually without changing the cable connections. This requires that it is possible to observe the head or flow rate. Status functions TM05 5804 4012 Pump with non return valve Fig. 26 Position of the pressure sensor and diaphragm tank Diaphragm tank The stop function requires a diaphragm tank of a certain minimum size. The tank must be installed as close as possible after the pump and the precharge pressure must be 0.7 x actual setpoint. Recommended diaphragm tank size: Rated flow of pump [gpm (m3/h)] Typical diaphragm tank size [gal (l)] 0-26 (0-6) 27-105 (7-24) 2 (7.5) 4 (15.1) If a diaphragm tank of the above size is installed in the system, the factory setting of ΔH is the correct setting. If the tank installed is too small, the pump will start and stop too often. The CU331SP shows the following data: • power consumption • operating hours • measured value • speed • input power • motor current. The status information can be shown in the display. Power consumption The value of the power consumption is an accumulated value calculated from the pump’s startup date and cannot be reset. No additional sensor is required. Operating hours The value of operating hours is an accumulated value calculated from the pump’s startup date and cannot be reset. No additional sensor is required. Measured value Sensor display will show the actual pressure as received from the pressure transducer. Speed Display will show the motor speed in RPM's (calculated). Input power Setting the direction of rotation The start-up guide is started the first time the CU331SP is connected to supply voltage. Then while going through the start-up guide, the CU331SP tests and sets the correct direction of rotation without changing the cable connections to the motor. The correct direction of rotation can be set in these ways: • automatic setting. • manual setting when the direction of rotation is not visible. Display will show the power consumption in kW. Motor current Display will show the actual motor current being used. Logging functions Alarm and warning log The latest five alarms and five warnings are logged with a timestamp corresponding to the power-on time after the fault has occurred. The alarm and warning log can be shown directly on the display. See section Warning and alarm list. 43 SQ, SQE, SQE-NE, CU331SP 11 CU331SP variable frequency drive Signal relays The table shows the function of the signal relays.

During start and in asymmetrical supply systems, the leakage current can be higher than normal and may cause the ELCB to trip. b The motor requires no external motor protection. The CU331SP protects the motor against thermal overloading and blocking. Protection against overcurrent The CU331SP has an internal overcurrent protection for overload protection on the motor output. Protection against mains voltage transients CU331SP electrical connection Ensure the correct grounding and protection procedures are used for the installation. Before the electrical installation, ensure that the power supply and other voltage inputs are switched off. Electrical protection Protection against electric shock, indirect contact The leakage current to ground exceeds 3.5 mA, and a reinforced ground connection is required. Protective conductors must always have a yellow/ green (PE) or yellow/green/blue (PEN) color marking. Instructions according to EN IEC 61800-5-1: • The CU331SP must be stationary, installed permanently and connected permanently to the mains supply. • The ground connection must be carried out with duplicate protective conductors or with a single reinforced protective conductor with a cross-section of minimum AWG 7 (10 mm2). The CU331SP is protected against mains voltage transients according to EN 61800-3, second environment. Mains and motor connection The supply voltage and frequency are marked on the CU331SP nameplate. Make sure that the CU331SP is suitable for the power supply of the installation site. The maximum output voltage of the CU331SP is equal to the input. Example: if the supply voltage is rated at 208V choose a 208V motor for operation. Mains switch A mains switch can be installed before the CU331SP according to local regulations. See fig. 32. Wiring diagram The wires in the terminal box must be as short as possible. Excepted from this is the ground wire, which must be so long that it is the last one to be disconnected in case the cable is inadvertently pulled out of the cable entry. The CU331SP and the supply system must be protected against short-circuit. Grundfos requires that the back-up fuses are used for protection against short-circuit. The CU331SP offers complete short-circuit protection in case of a short-circuit on the motor output. TM05 5867 3912 Protection against short-circuit, fuses Fig. 32 CU331SP wiring diagram Additional protection The leakage current to ground exceeds 3.5 mA. If the CU331SP is connected to an electrical installation where an earth leakage circuit breaker (ELCB) is used as additional protection, the circuit breaker must be of a type marked with the following symbols: Terminal 91 (L1) 92 (L2) 95/99 (PE) Function Single-phase supply Ground connection For single-phase connection, use L1 and L2.

Follow these guidelines to meet EN 61800-3, first environment. • Use only motor and signal cables with a braided metal screen in applications without output filter. • There are no special requirements to supply cables, apart from local requirements. • Leave the screen as close to the connecting terminals as possible. See fig. 44. • Avoid terminating the screen by twisting the ends. See fig. 45. Use cable clamps or EMC screwed cable entries instead. • Connect the screen to frame at both ends for both motor and signal cables. If the controller has no cable clamps, connect only the screen to the CU331SP. • Avoid unscreened motor and signal cables in electrical cabinets with variable frequency drives. • Make the motor cable as short as possible in applications without output filter to limit the noise level and minimize leakage currents. • Screws for frame connections must always be tightened whether a cable is connected or not. • Keep main cables, motor cables and signal cables separated in the installation, if possible. Other installation methods may give similar EMC results if the above guidelines for good practice are followed. To meet the EMC requirements, the CU331SP comes with the following types of built-in radio frequency interference filter (RFI). Voltage Typical shaft power P2 RFI filter type 1 x 200-240 V * 1.5 - 10 hp C1 *Single-phase input - three-phase output. Description of RFI filter types C1: For use in domestic areas. RFI filter types are according to EN61800-3 Control panel The on/off button on the control panel does not disconnect the CU331SP from the power supply and must therefore not be used as a safety switch.
