ecocirc 19-14 auto 6050B2000 auto – Proportional Pressure 9.25 lb

Description

ecocirc 19-14 auto are designed, with highly efcient electronically commutated

permanent magnet motor (ECM/PM Technology), specically for hydronic systems.

Ideal for hydronic systems with zone or thermostatic valves, the ecocirc 19-14 auto can

be used as replacements for existing circulators with induction motors as well as new

construction as primary or zone circulators.

The ecocirc 19-14 auto has a proportional pressure control logic, which allows the pump to

slow down automatically as it approaches shut off condition (as the valve closes) then ramp

up when the demand increases (as the valve opens).

It includes a step-less dial to adjust the speed to meet the system requirements.

Built-in Software Protection (for auto and vario)

ecocirc 19-14 has built-in protection to protect from installation

errors and improper usage.

There is an overload protection to protect the electronics from

over-current or over-voltage input. To further protect the electronics

from damage, there is an over-temperature protection. This built-in

protection will rst slow the speed down to continue operation, but

will shut down if the temperature of the electronics continues to rise

to high levels.

The circulator is also protected against dry-run condition. Built-in

software will recognize a change in performance and determine that

the circulator is dry-running. Automatically the circulator will stop

operating and will need to be reset to continue operation.

The circulator continually monitors the system for any change in

power input or dry-run condition or electronic’s temperature. If any

error is detected, the circulator will shut down and will need to be

reset to continue operation after the error has been xed.

Always easy to access. The screw ring design

results in a pump motor that can be rotated in

any position around the 360° circle. Therefore the

electrical connection as well as the control dial is

easy to access.

Our design separates the magnetic chamber from the ow

(for auto and vario)

Magnetite and sludge, which are both found in the pumped liquid and are both

magnetic, can accumulate at the permanent magnetic parts of a high efciency

pump, and therefore block and damage it. The Anti-Block Technology separates the

main ow of the pumped media completely from the permanent magnetic parts.

It is virtually impossible for the ecocirc auto or vario to block-up even in an old

open system.

The main ow of the pumped media

(blue) and its magnetite and sludge

particles (red) ow outside the inuence

area of the permanent magnet rotor

(bottom).

The side ow of the wet running

circulators, which is required for

lubrication and cooling of the bearing,

is separated from the main ow with its

magnetite and sludge.

Description

ecocirc 19-14 vario circulators are designed, with highly efcient electronically

commutated permanent magnet motor (ECM/PM technology), specially for

hydronic systems.

The ecocirc 19-14 vario has a constant curve control, which allows the pump to

follow the natural hydraulic curve of a circulator. Basically acts the same as a

standard 3-speed pump except with a step-less dial resulting in innite

speed control.

ecocirc 19-14 vario is ideal for replacement for existing circulators with induction

motors as well as new construction as primary or zone circulators.

High visibility

Even in dark mechanical rooms, a

bright display with large gures

and symbols makes it easy to view

pump status.

User-friendly interface

With only four logically placed buttons on

an intuitive interface, it’s easy to set and

operate the new ecocirc XL. Advanced

settings enable custom programming,

accessible via a PC, smartphone or wireless

enabled device.

Sensorless technology

The ecocirc XL variable speed drive has the pump’s hydraulic

performance mapped in memory for multiple RPMs with

corresponding electric current values (similar to the ITSC Sensorless

VS Drive). The Delta P value associated with the pump’s actual

operating point is compared to the setpoint Delta P and the

controller makes speed adjustments using current to minimize

the differences between actual Delta P and setpoint Delta P.

Chilled water applications

Electronics are separated from the pump

to prevent condensation for worry free

operation even at 14ºF (-10ºC).

Increase your control options

Multiple inputs including start-stop,

temperature control, pressure regulation

and advanced Modbus or BACnet

control provide dynamic system

management.

Economical operation

A highly efcient ECM motor

combined with optimized pump

hydraulics, keeps operational

costs at a minimum.

Keep it hot or cold

A closed, perfectly molded

insulation shell preserves a

constant temperature of the

pumped liquid.

Input Signals

• One 0-10V (Analog): Speed Control by external controller

• One 4-20mA (Analog): Connection with an external differential pressure

sensor for the pressure control mode (two different pressure sensor

range: 0-15 PSI PN: 104503 and 0-30 PSI PN: 104504

• One external temperature sensor input for either Constant Temperature

or Temperature Inuenced modes. Sensor PN: 104502

• One built-in temperature sensor for either Constant Temperature or

Temperature Inuenced modes.

Remote Building Management System Capabilities

• The pump can be monitored or controlled by a signal from a BMS

(Building Management System). Built-in protocols are BACnet and

Modbus. Direct connection to a PC is available.

• An optional wireless module can be added to create a short range

wireless eld for remote connection to the pump. An internet browser

or an App can be used to program the advanced settings.

STANDARD OPERATING MODES

Constant Speed

The pump maintains a constant speed at any ow rate. The desired

speed is set on the interface panel of the pump.

Constant Pressure (Δp-c)

The pump maintains a constant differential pressure at any ow

demand until the maximum speed is reached. The desired head of

the pump can be set via user interface. Recommended for use in

systems with small or constant pressure losses.

Proportional Pressure (Δp-v)

The differential pressure continuously increases or deceases based

on the ow demand. The set point head can be set on the pump

user interface. Use for systems with large pressure losses.

HGG

Night Mode

The pump will automatically reduce speed when there is

an abrupt change in uid temperature. The change in uid

temperature is from a boiler operating in night time setback

mode. The built-in temperature sensor is used. (Fixed Speed,

Constant Pressure, Proportional Pressure)

CONSTANT TEMPERATURE SPEED CONTROL

T- Constant Control

This control mode will use a PI algorithm to vary the speed of the pump

in order to maintain a constant temperature of the uid media.

ΔT-Constant Control

This control mode will use a PI algorithm to vary the speed of the pump

in order to maintain a constant differential temperature between the

built-in temperature sensor and external temperature sensor.

CIRCULATORS ecocirc® wireless

Potable Hot Water Recirculation Kit

Description

The ecocirc wireless is a potable hot water recirculation kit (a pump and valve

combination) for instant supply of hot water supply throughout the entire house.

The ecocirc pump is installed on the supply side of the hot water source and the

mixing valve under the sink farthest away from the hot water source. The pump

and valve are in constant wireless communication.

How it Works

The desired water temperature at the valve is set directly on the pump with the

thermostat dial. The water temperature is constantly checked by the valve and the

temperature values are sent to the pump. At approximately 5°F below the desired

water temperature, the pump will begin to circulate hot water. This circulation will

open the valve for hot water to cross into the cold water line, which creates a return

loop back to the hot water source. When the desired temperature is reached, the

pump will stop circulating. This is to prevent continuous circulation.

An Optional Push Button / Signal Repeater

A wireless device to provide instant hot water with a push of a button. The push button

device will override the timer operation and activate the pump to circulate hot water

until the desired temperature is met at the valve. This device also functions as a signal

repeater when the pump and valve have a weak signal due to distance or interference.

CIRCULATORS ecocirc® SC Solar Pump

Spherical Motor Pump

Application

• The ecocirc solar pump can be used for most circulation pump

applications without connection to the power grid with direct

connection to a photovoltaic panel.

• This pump is perfect for single family home thermal

solar systems or any circulation pump application where

conventional power is not available, on closed loop systems

Design

• The only moving part is a hemispherical rotor/impeller unit

which sits on an ultra-hard, wear-resistant ceramic ball.

• There are no conventional shaft bearings or seals eliminating

bearing noise and seal leaks.

• This pump is robust and has an estimated service life in excess

of 50,000 hours.

• All parts exposed to the  uid are completely corrosion resistant.

Soft Start-up

• When the photovoltaic panel provides suf cient power, the

pump goes through the alignment phase by turning the rotor

into the position required for start-up.

• The processor then waits until the capacitor is suf ciently

charged.

• This enables a start-up with minimal power (less than one watt).

Over-temperature Safety Device

• The ecocirc solar pump comes with an integrated over-

temperature safety device which shuts off the pump electronics

when reaching temperatures over 230°F.

• After reaching a critical temperature 203°F the pump will lower

its speed automatically in order to avoid a total shutdown.

Long bronze sleeve bearings maintain

exact shaft alignment. Provides for constant

circulation of oil over bearing surfaces.

Precision ground pump shaft is

oversized to provide large bearing

surfaces. Hardened integral thrust

collar minimizes end-thrust to

ensure long seal and bearing life.

The B&G mechanical seal is

designed to withstand the wide

range of water temperatures,

pressures, additives and dissolved

solids common in hydronic

systems.

Centrifugal impeller prevents

accumulation of air at seal faces to assure

long life. Close impeller/body tolerances

minimize water slippage and maximize

TC-1 Automatic Timer Kit (Part No. 113210)

To increase the overall efficiency of a hot water recirculation

system, the TC-1 timer control kit can be installed for use on any

B&G NBF circulator. The TC-1 timer control is programmable to

turn the circulator ON and OFF automatically at preset times. This

permits the user to have the pump circulate hot water only during

those times when high usage can be expected throughout the

day. Power supply minimum interval switch is 15 minutes.

Run modes maximum switch current is 16 amps.

Description

To increase the overall efficiency of a domestic hot water recirculating system and to reduce water

wasted while waiting for hot water, the e3 Timer can be installed on all e3 pumps. The timer is easily

installed by removing the motor end cap, plugging in the timer and setting the timer schedule

without any wiring. The timer can be used in 3-different selections: ON, OFF and TIMER. The ON

selection operates the pump continuously, the OFF selection turns the pump OFF and the TIMER

selection (depicted by a clock on the timer) turns the pump on when programmed.

Operational Limits

Power Supply: Internally powered by the e3 circulating pump

Minimum Switch Interval: 30 minutes

Run Modes: ON (Continuous), OFF (Off at all times) and TIMER

(run at programmed intervals)

AQS-1/2 (Part No. 113223) and

AQS-3/4 (Part No. 113224) Aquastat

Designed to thermostatically turn any B&G NBF circulator ON and

OFF. The AQ-1/2 or AQ-3/4 will switch the pump OFF at 120ºF

(48.9ºC) and ON at 100ºF (37.8ºC). The aquastats are available

in separate models that will sense the temperature for either

1/2” or 3/4” copper pipe.

RELAYS ZONETROL II AZ-1A™ Snap-On Pump Relay

Description

The ZONETROL II AZ-1A snap on relay box is an easy to install single zone

pump controller that mounts directly on any Bell & Gossett wet rotor circulator

NRF/NBF or Series PL booster. The AZ-1A turns the pump and boiler ON as

thermostat calls for heat. Using the wire nuts provided with the package, the

AZ-1A is quickly assembled onto any NRF/NBF or 1/12 to 1/6 HP Series PL.

The clearly marked TT terminals for the thermostat and the XX isolated end

switch terminals make the rest of the hook-up a snap. The AZ-1A can be

daisy-chained together to form a maximum of three zones.

The Bell & Gossett AZ-1A is ideal for any single to three zone pump

application. Or can be used when adding a zone to an existing system. There’s

no more need to have a pump controller hanging on the wall, simply install

the AZ-1A to our NRF/NBF or Series PL circulators and you are finished.

Features

• Snap-on design allows the AZ-1A to be quickly attached

to any B&G wet rotor circulator, reducing your inventory

investment (no need to carry “special” circulators with

factory mounted controllers)

• Clearly marked terminals make for sure, fast wiring of

the system

• Compact design fits in tight locations and presents a

clean professional appearence

• 100% factory tested assures reliable operation

• 5 year warranty — the best in the industry

• Daisy-Chain the AZ-1A relays to form up to three zones

• Can be used on any B&G model NRF, NBF or 1/12 to 1/6

HP Series PL pumps

Specifications

Description

The Hydrotrol (HT) flow control valve is used to prevent overheating of zones

due to gravity flow in hydronic heating systems and will permit summer-winter

operation of indirect water heater. The HT valve allows fluid to pass when the

system or zone pumps start. When the system or zone pumps are not operating,

the HT valve remains closed, preventing gravity circulation. The HT valves are

designed with a 1/2 turn knob that can be manually opened when draining

the system or for bypass purposes. The HT valve can be installed in either the

horizontal or vertical orientation.

VALVES DB–Differential Bypass Valve

Description

The differential bypass valve is used in systems where heating

loads may be excluded from the circuit as zone valves close.

It controls the excess flow in the system by acting as a bypass

while ensuring adequate flow to the remaining open circuits.

The differential bypass valve helps reduce velocity noise

caused by excess flow through the circuits while maintaining

the pump head at a constant value.

Enhanced Air Separator

AIR SEPARATORS EASB-Jr Enhanced Air Separator

Description

Bell & Gossett’s Model EAS Enhanced Air

Separator is a patented, innovative design in air

separators. It has been engineered to remove

entrained air from hydronic heating and cooling

systems providing far superior air removal

compared with other devices available today.

The EAS is ideal for residential, institutional

and light commercial applications.

Description

Bell & Gossett’s Model EASB-

JR Enhanced Air Separator

automatically removes entrained

air bubbles in hydronic systems. As

fluid enters the EASB-JR, the velocity

is decreased creating a low pressure

area. The small bubbles are released

from fluid and then collected on the

coalescing medium. As the bubbles

coalesce, they rise to the top of the

air separator where they are released

to atmosphere through the built-in

automatic air vent. The air separator

has a bottom 1/2” NPT connection

to accommodate a B&G diaphragm

expansion tank. The compact design

and brass body construction make

the EASB-JR ideal for residential

and commercial hydronic heating

systems.

How It Works

1 As system fluid enters

through the inlet, (either

straight or angle) the diffuser

distributes flow evenly across

the stainless steel, wire

brush-like medium.

2 Air bubbles, even micro air

bubbles, stick to the brush

filaments.

3 Trapped air rises above the

diffuser through a baffle (not

pictured), where the air is

then released through

an opening on top.

4 Deaerated water then goes

back into the system.

TANKS HFT Diaphragm Tanks • Expansion Tanks for Hydronic Heating

Airtrol® Tank Fittings

Directs free air to the compression tank. Restricts thermal

circulation to boiler. Establishes initial tank air level.

Allows compression tank size reduction.

Description

Bell & Gossett HFT expansion tanks

are designed to absorb the force

of thermal expansion in hydronic

heating systems. Series HFT tanks

for hydronic heating systems are

available in sizes from 2—86 gallons.

The Series HFT tank is designed

to absorb the force of thermal

expansion of heating water to

maintain proper pressurization in a

closed hydronic system. The heavy

duty butyl diaphragm separates

system water from the air in the tank

preventing water logging problems.

Specifications

Description

Combination full port shut-off valve and drain valve used

to connect an expansion tank to the system. It is important

that the pre-charge in an expansion tank be maintained at

the proper pressure at all times. This pressure is the lowest

system operating pressure. When the tank’s pressure is

adjusted, there should be no system liquid in it. This

pre-charge should be checked and adjusted when:

• Tank is first installed

• If system is started or operating with the incorrect

tank pre-charge

• Annually to assure proper pre-charge pressure at all times

The TPV (Tank Purge Valve) is ideal for this as the tank can

be isolated from the system, drained and the pre-charge

checked and adjusted without draining or shutting down

the system.

The TPV also serves as a service valve should the tank need to

be removed or have the bladder changed. These valves are

furnished standard with a drain valve with a standard 5/8”

hose connection.

These valves are not recommended to be used on

potable water tanks.

HEAT EXCHANGERS Brazed Plate Heat Exchangers

Description

Model BPX brazed plate heat exchangers offer the highest level

of thermal efficiency and durability in a compact, low cost unit.

The corrugated plate design provides very high heat transfer

coefficients, resulting in a more compact design. The unit’s

stainless steel plates are vacuum brazed together to form a

durable, integral piece that can withstand high pressure

and temperature.

The BPX heat exchangers offer a compact design compared to

shell and tube exchangers

• 1/6 the size of shell and tube

• 1/5 the weight of shell and tube

• 1/8 the liquid required of shell and tube

• 1/3 to 1/5 of the surface area required

BPX units are ideal for a wide variety

of hydronic applications such as:

• Radiant Floor Heating

• Domestic Water Heating

• Snow MELT Systems

• Swimming Pool Heating

1) Provides approx. 2º F per hour heating with 180º F boiler to achieve 80º F pool temperature.

2) Pool water ﬂow rate usually requires ﬂow by pass from main pool circulation.

3) Chlorinated pool water can be corrosive to SS316L and Copper. Proper control of chlorine levels is

required or alternate materials of construction should be considered.

Estimate how much heat you need:

Flow x Temperature Rise x 500 = Heat load

Example: (20 GPM) (20º F) (500) = 200,000 BTU/Hr

For a Radiant Heating Application, the choice would

be a BP400-40.

1) Provides approx. 2º F per hour heating with 180º F boiler to achieve 80º F pool temperature.

2) Pool water ﬂow rate usually requires ﬂow by pass from main pool circulation.

3) Chlorinated pool water can be corrosive to SS316L and Copper. Proper control of chlorine levels is

required or alternate materials of construction should be considered.

Estimate how much heat you need:

Flow x Temperature Rise x 500 = Heat load

Example: (20 GPM) (20º F) (500) = 200,000 BTU/Hr

For a Radiant Heating Application, the choice would

be a BP400-40.

1) Provides approx. 2º F per hour heating with 180º F boiler to achieve 80º F pool temperature.

2) Pool water ﬂow rate usually requires ﬂow by pass from main pool circulation.

3) Chlorinated pool water can be corrosive to SS316L and Copper. Proper control of chlorine levels is

required or alternate materials of construction should be considered.

Estimate how much heat you need:

Flow x Temperature Rise x 500 = Heat load

Example: (20 GPM) (20º F) (500) = 200,000 BTU/Hr

For a Radiant Heating Application, the choice would

be a BP400-40.

1) Provides approx. 2º F per hour heating with 180º F boiler to achieve 80º F pool temperature.

2) Pool water ﬂow rate usually requires ﬂow by pass from main pool circulation.

3) Chlorinated pool water can be corrosive to SS316L and Copper. Proper control of chlorine levels is

required or alternate materials of construction should be considered.

Estimate how much heat you need:

Flow x Temperature Rise x 500 = Heat load

Example: (20 GPM) (20º F) (500) = 200,000 BTU/Hr

For a Radiant Heating Application, the choice would

be a BP400-40.

The Little Red Schoolhouse® - Training the Industry

Genuine Bell & Gossett Parts

When replacing parts in your customers’ B&G booster or other

hydronic specialties, don’t settle for anything other than genuine

B&G parts. You owe it to your customers and to yourself to do it

right the first time.

Bell & Gossett parts are designed and engineered strictly for the

Bell & Gossett boosters. Substitute parts may seem to cost less.

But more often than not, they actually cost a lot more, when they

do not hold up on the job. Then you are faced with callbacks and

your reputation is at stake.

So why risk having to replace a replacement part?

Stick with the real thing — from Bell & Gossett.
