6. Applications

Note

The pumps are designed to circulate hot or cold water in:

• heating systems

• district heating plants

• air-conditioning systems

• cooling systems. In addition, the pumps are used for liquid transfer and water

supply in:

• washing systems

• domestic hot-water systems

• industrial systems in general. To ensure optimum operation, the sizing range of the system

must fall within the performance range of the pump.

6.1 Pumped liquids

Warnin g If the pump is used for a liquid which is

hazardous, it will be classified as contaminated. In such cases, the proper precautions must be taken to avoid injury to health when operating or working on the pump.

The pump is suitable for thin, clean, non aggressive and nonflammable liquids, not containing solid particles or fibers that may attack the pump mechanically or chemically.

Examples:

• central heating system water (the water should meet the requirements of accepted standards on water quality in heating systems)

• cooling liquids

• domestic hot water

• industrial liquids

• softened water.

The pumping of liquids with a density and/or kinematic viscosity higher than that of water will cause the following:

• a considerable pressure drop

• a drop in hydraulic performance

• a rise in power consumption.

In such cases, fit the pump with a bigger motor. If in doubt, contact Grundfos.

The EPDM O-rings fitted as standard are primarily suitable for water.

If the water being pumped contains minerals, synthetic oil, chemicals, or any liquids other than water, choose the O-rings accordingly.

7. Operating conditions

7.1 Maximum number of starts and stops

The number of starts and stops via the power supply must not exceed four times per hour.

When switched on via the power supply, the pump will start after approx. 5 seconds.

If you want a higher number of starts and stops, use the input for external start/stop when starting/stopping the pump.

When started via an external on/off switch, the pump will start immediately.

7.2 Alternating operation of twin-head pumps

On twin-head pumps, the duty and backup pumps must be alternated on a regular basis, i.e. once a week, to ensure an even distribution of the operating hours on both pumps. As default, the pumps alternate automatically. See section 16.1 Multi-pump

setup.

If you use twin-head pumps for pumping domestic hot water, the duty and backup pumps must be alternated on a regular basis, i.e. once a day, to avoid blocking of the backup pump due to deposits (calcareous deposits, etc.). As default, the pumps alternate automatically. See section 16.1 Multi-pump setup.

7.3 Liquid temperature

-13 °F (-25 °C) up to 248 °F (+120 °C). The maximum liquid temperature depends on the mechanical

shaft seal type and the pump type. Depending on the cast-iron version and the pump application, the

maximum liquid temperature may be limited by local regulations and laws.

The maximum liquid temperature is stated on the pump nameplate.

If the pump is operating with liquids at high temperatures, the life of the shaft seal may be reduced. It may be necessary to replace the shaft seal more often.

7.4 Ambient temperature

7.4.1 Ambient temperature during storage and transportation

-22 to 140 °F (-30 to +60 °C).

7.4.2 Ambient temperature during operation

-4 to 122 °F (-20 to +50 °C). The motor can operate with the rated power output (P2) at

122 °F (50 °C), but continuous operation at higher temperatures will reduce the expected product life. If the motor is to operate at ambient temperatures between 122 and 140 °F (50 and 60 °C), select an oversized motor. Contact Grundfos for further information.

7.6 Inlet pressure

To ensure optimum and quiet pump operation, the inlet pressure (system pressure) must be adjusted correctly. See table on page 51.

For the calculation of specific inlet pressures, contact the local Grundfos company or see the data booklet for TP(D), TPE(D), TPE2 (D) and TPE3 (D) on www.grundfos.us.

7.7 Electrical data

See sections 26. Technical data, single-phase motors and

27. Technical data, three-phase motors.

For specific motor data, see the motor nameplate.

7.8 Sound pressure level

The sound pressure level of the pump is lower than 70 dB(A).

7.9 Environment

Non-aggressive and non-explosive atmosphere.

7.10 Installation altitude

The motor must not be installed more than 6562 ft (2000 m) above sea level.

Installation altitude is the height above sea level of the installation site.

• Motors installed up to 3281 ft (1000 m) above sea level can be loaded 100 %.

• Motors installed more than 3281 ft (1000 m) above sea level must not be fully loaded due to the low density and consequent low cooling effect of the air. See fig. 3.

7.11 Air humidity

Maximum air humidity: 95 %. If the air humidity is constantly high and above 85 %, one of the

drain holes in the drive-end flange must be open. See section

5. Delivery and handling.

7.12 Motor cooling

To ensure cooling of motor and electronics, observe the following:

• Position the motor in such a way that adequate cooling is

ensured. See section 8.7 Ensuring motor cooling.

• The temperature of the cooling air must not exceed 122 °F (50 °C).

• Keep cooling fins and fan blades clean.

Washer Pump

11.81" [300 mm]

Caution

Warnin g When pumping hot or cold liquids, make sure

that persons cannot accidentally come into contact with hot or cold surfaces.

In order to maintain the UL mark, additional installation procedures must be followed. See page 50.

Install the pump in a dry well-ventilated, but frost-free position. When installing pumps with oval bolt holes in the pump flange,

use washers as shown in fig. 4.

Fig. 4 Use of washers for oval bolt holes

Arrows on the pump housing show the direction of flow of liquid through the pump.

You can install the pump in horizontal or vertical pipes.

The motor must never fall below the horizontal plane.

For inspection and removal of motor or pump head, a clearance of 11.81" (300 mm) is required above the motor. See fig. 5.

Fig. 5 Required clearance above the motor

If the liquid temperature falls below the ambient temperature, condensation may form in the motor during inactivity. In this case, make sure that one of the drain holes in the motor flange is open and points downwards. See fig. 7.

Fig. 7 Drain hole in motor flange

If twin-head pumps are used for pumping liquids with a temperature below 32 °F (0 °C), condensed water may freeze and cause the coupling to get stuck. You can solve the problem by installing heating elements. Whenever possible, install the

TM01 0683 1997

pump with the motor shaft in horizontal position. See fig. 6.

Observe the conditions in section 11. User

interfaces.

8.1 Pipework

Fit isolating valves on either side of the pump to avoid draining the system if the pump needs to be cleaned or repaired.

The pump is suitable for pipeline mounting, provided that the pipes are adequately supported on either side of the pump.

Single-head pumps are designed for pipeline mounting only. Twin-head pumps are prepared for installation on a mounting

bracket or base plate. When installing the pipes, make sure that the pump housing is

not stressed by the pipework. The suction and discharge pipes must be of an adequate size,

taking the pump inlet pressure into account. To avoid sediment build-up, do not fit the pump at the lowest point

of the system. Install the pipes so that air locks are avoided, especially on the

suction side of the pump. See fig. 8.

TM05 7916 1613TM05 7983 1713

English (US)

TM05 7917 1613

Twin-head pumps installed in horizontal pipes must be fitted with an automatic air vent in the upper part of the pump housing. See fig. 6.

The automatic air vent is not supplied with the pump.

Fig. 6 Automatic air vent

TM00 2263 0195

Fig. 8 Correct pipework on the suction side of the pump

The pump must not run against a closed discharge valve as this will cause an increase in temperature/formation of steam in the pump which may cause damage to the pump.

If there is any risk of the pump running against a closed discharge valve, ensure a minimum liquid flow through the pump by connecting a bypass/a drain to the discharge pipe. You can for instance connect the drain to a tank. A minimum flow rate equal to 10 % of the flow rate at maximum efficiency is needed at all times.

Flow rate and head at maximum efficiency are stated on the pump nameplate.

8.6 Frost protection

Pumps which are not being used during periods of frost must be drained to avoid damage.

8.7 Ensuring motor cooling

In order to ensure sufficient cooling of the motor, the distance (D) between the end of the fan cover and a wall or other fixed objects must always be at least 2.0" (50 mm), irrespective of motor size. See fig. 14.

TM06 0724 0814

English (US)

8.4 Base plate

Twin-head pumps have tapped holes in the bottom of the pump housing. The holes can be used for mounting a base plate.

8.5 Insulation

Do not insulate the motor stool as this will trap any vapor escaping from the shaft seal, thus causing corrosion. Covering the motor stool with insulation will also make inspection and service difficult.

Follow the guidelines in fig. 13 when insulating the pump.

Fig. 13 Insulation of TPE2, TPE3 pumps

Fig. 14 Minimum distance (D) from the motor to a wall or other

fixed objects

8.8 Outdoor installation

When installed outdoors, the motor must be provided with a suitable cover to avoid condensation on the electronic components. See fig. 15.

When fitting a cover to the motor, observe the guideline in section 8.7 Ensuring motor cooling.

The cover must be sufficiently large to ensure that the motor is not exposed to direct sunlight, rain or snow. Grundfos does not supply covers. We therefore recommend that you have a cover built for the specific application. In areas with high air humidity, we recommend that you enable the built-in standstill heating function.

All inputs and outputs are internally separated from the power supply-conducting parts by reinforced insulation and galvanically separated from other circuits. All control terminals are supplied by safety extra-low voltage (SELV), thus ensuring protection against electric shock.

• Signal relay outputs – Signal relay 1:

LIVE: Power supply voltages up to 250 VAC can be connected to this output. SELV: The output is galvanically separated from other circuits. Therefore, the supply voltage or safety extra-low voltage can be connected to the output as desired.

– Signal relay 2:

SELV: The output is galvanically separated from other circuits. Therefore, the supply voltage or safety extra-low voltage can be connected to the output as desired.

• Power supply (terminals N, PE, L or L1, L2, L3, PE).

A galvanically safe separation must fulfil the requirements for reinforced insulation including creepage distances and clearances specified in EN 61800-5-1.

TM02 1325 4402 TM05 3973 1812

10.1 Flushing the pipe system

The pump is not designed to pump liquids containing solid particles such as pipe debris and welding slag. Before starting up the pump, clean the pipe system thoroughly, and flush and fill it with clean water.

The warranty does not cover any damage caused by flushing the pipe system by means of the

pump.

Do not start the pump until it has been filled with liquid and vented. To ensure correct venting, the vent screw should point upwards.

Warnin g Pay attention to the direction of the vent hole,

and make sure that the escaping hot or cold liquid does not cause injury to persons or damage to the equipment.

TM02 8842 0904

Page 17

Open systems where the liquid level is below the pump inlet

The suction pipe and the pump must be filled with liquid and vented before you start the pump.

1. Close the discharge isolating valve and open the isolating valve in the suction pipe.

2. Loosen the air vent screw. See fig. 26.

3. Remove the plug from one of the pump flanges, depending on the pump location.

4. Pour liquid through the priming port until the suction pipe and the pump are filled with liquid.

5. Replace the plug and tighten securely.

6. Tighten the air vent screw.

The suction pipe can to some extent be filled with liquid and vented before it is connected to the pump. You can also install a priming device before the pump.

Fig. 26 Position of air vent screw

10.3 Starting

1. Before starting the pump, completely open the isolating valve on the suction side of the pump and leave the discharge isolating valve almost closed.

2. Start the pump. See section 11. User interfaces.

3. Vent the pump during starting by loosening the air vent screw in the motor stool until a steady stream of liquid runs out of the vent hole. See fig. 26.

Warnin g Pay attention to the direction of the vent hole,

and make sure that the escaping hot or cold liquid does not cause injury to persons or damage to the equipment.

4. When the pipe system has been filled with liquid, slowly open the discharge isolating valve until it is completely open.

10.4 Shaft seal run-in

The seal faces are lubricated by the pumped liquid, meaning that there may be a certain amount of leakage from the shaft seal.

When the pump is started up for the first time, or when a new shaft seal is installed, a certain run-in period is required before the leakage is reduced to an acceptable level. The time required for this depends on the operating conditions, i.e. every time the operating conditions change, a new run-in period will be started.

Under normal conditions, the leaking liquid will evaporate. As a result, no leakage will be detected.

However, liquids such as kerosene will not evaporate. The leakage may therefore be seen as a shaft seal failure.

11. User interfaces

Warnin g The product may be so hot that only the buttons

must be touched to avoid burns.

Pump settings can be made by means of the following user interfaces:

Changeover between normal duty and night setback depends on the flow-pipe temperature.

The pump automatically changes over to night setback when the built-in sensor registers a flow-pipe temperature drop of more than 18 to 27 °F (10 to 15 °C) within approx. two hours. The temperature drop must be at least 1.8 °F/min (0.1 °C/min).

Changeover to normal duty takes place without a time lag when the temperature has increased by approx. 18 °F (10 °C).

Function

Select one of these functions:

• Not active When set to "Not active", the input has no function.

• External stop When the input is deactivated (open circuit), the pump will stop.

• Min. (minimum speed) When the input is activated, the pump will run at the set min. speed.

• Max. (maximum speed) When the input is activated, the pump will run at the set max. speed.

• External fault When the input is activated, a timer will be started. If the input is activated for more than 5 seconds, the pump will be stopped and a fault will be indicated.

• Alarm resetting When the input is activated, a possible fault indication will be reset.

• Dry running When this function has been selected, lack of inlet pressure or water shortage can be detected. When lack of inlet pressure or water shortage (dry running) is detected, the pump will be stopped. The pump cannot restart as long as the input is activated. This requires the use of an accessory, such as these:

– a pressure switch installed on the suction side of the pump – a float switch installed on the suction side of the pump.

• Accumulated flow When this function has been selected, the accumulated flow can be registered. This requires the use of a flowmeter which can give a feedback signal as a pulse per defined flow of water. See section 15.17.1 Pulse flow meter setup.

• Predefined setpoint digit 1 (applies only to digital input 2) When digital inputs are set to predefined setpoint, the pump will operate according to a setpoint based on the combination of the activated digital inputs. See section 15.15.2 Predefined setpoints.

The temperature influence function requires the following:

• Proportional-pressure, constant-pressure or constant-curve control mode.

• Pump installed in flow pipe.

• System with flow-pipe temperature control.

Temperature influence is suitable for the following systems:

• Systems with variable flows (for example two-pipe heating systems) in which the enabling of the temperature influence function will ensure a further reduction of the pump performance in periods with small heating demands and consequently a reduced flow-pipe temperature.

• Systems with almost constant flows (for example one-pipe heating systems and underfloor heating systems), in which variable heating demands cannot be registered as changes in the head as is the case with two-pipe heating systems. In such systems, you can only adjust the pump performance by enabling the temperature influence function.

15.16 Monitoring functions

15.16.1 Limit-exceeded function

Pump variant Limit-exceeded function

TPE3 (D) TPE2 (D) ●

This function can monitor set limits of analog values. It will react if the values exceed the limits. Each limit can be set as a maximum or minimum value. For each of the monitored values, you must define a warning limit and an alarm limit.

The function makes it possible to monitor two different locations in a pump system at the same time. For instance the pressure at a consumer and the pump discharge pressure. This ensures that the discharge pressure does not reach a critical value.

If the value exceeds the warning limit, a warning is given. If the value exceeds the alarm limit, the pumps will be stopped.

You can set a delay between the detection of an exceeded limit and the activation of a warning or an alarm. You can also set a delay for resetting a warning or an alarm.

You can reset a warning automatically or manually. Furthermore, you canset whether the system is to restart

automatically after an alarm, or if the alarm must be reset manually. Restarting can be delayed by an adjustable time. You can also set a startup delay ensuring that the system reaches a steady state before the function becomes active.

15.17.2 Ramps

Pump variant Ramps

TPE3 (D) TPE2 (D) ●

The setting of ramps is only relevant in the case of constant-curve operation.

The ramps determine how quickly the motor can accelerate and decelerate, respectively, during start/stop or setpoint changes.

The following can be set:

• acceleration time, 0.1 to 300 s

• deceleration time, 0.1 to 300 s.

The times apply to the acceleration from stop to rated speed and the deceleration from rated speed to stop, respectively.

At short deceleration times, the deceleration of the motor may depend on load and inertia as there is no possibility of actively braking the motor.

If the power supply is switched off, the deceleration of the motor will only depend on load and inertia.

16.1 Multi-pump setup

Pump variant Multi-pump setup

TPE3 (D) ● TPE2 (D) ●

The multipump function enables the control of single-head pumps connected in parallel or twin-head pumps without the use of external controllers. The pumps in a multipump system communicate with each other via the wireless GENIair connection or the wired GENI connection.

You set up a multipump system via a selected pump, i.e. the master pump (first selected pump). You can connect all Grundfos pumps with a wireless GENIair connection to the multipump system.

The multipump functions are described in the following sections.

16.1.1 Alternating operation

Only one pump is operating at a time. The change from one pump to the other depends on time or

energy. If a pump fails, the other pump will take over automatically.

Pump system:

• Twin-head pump.

• Two single-head pumps connected in parallel. The pumps must be of the same type and size. Each pump requires a non-return valve in series with the pump.

16.1.2 Backup operation

One pump is operating continuously. The backup pump is operated at intervals to prevent seizing up. If the duty pump stops due to a fault, the backup pump will start automatically.

Pump system:

• Twin-head pump.

• Two single-head pumps connected in parallel. The pumps must be of the same type and size. Each pump requires a non-return valve in series with the pump.

16.1.3 Cascade operation

Cascade operation ensures that the pump performance is automatically adapted to the consumption by switching pumps on or off. The system thus runs as energy-efficiently as possible with a constant pressure and a limited number of pumps.

When a twin-head pump is running in constant-pressure control mode, the second pump head will start at 90 % and stop at 50 % performance.

All pumps in operation will run at equal speed. Pump changeover is automatic and depends on energy, operating hours and fault.

Pump system:

• Twin-head pump.

• Two to four single-head pumps connected in parallel. The pumps must be of the same type and size. Each pump requires a non-return valve in series with the pump.

• The control mode must be set to "Const. pressure" or "Const. curve".

energy is used for pumping too much liquid into the system. In systems with mixing loops, you can use the control mode to control the flow in each loop. Benefits:

• Enough water for all loops at peak load conditions if each loop has been set to the right maximum flow.

• The dimensioned flow for each zone (required heat energy) is determined by the flow from the pump. This value can be set precisely in the FLOW throttling valves.

• When the flow is set lower than the balancing valve setting, the pump will ramp down instead of losing energy by pumping against a balancing valve.

• Cooling surfaces in air-conditioning systems can operate at high pressure and low flow.

In systems with relatively large pressure losses in the distribution pipes and in air-conditioning and cooling systems.

• Two-pipe heating systems with thermostatic valves and

– very long distribution pipes – strongly throttled pipe balancing valves – differential-pressure regulators – large pressure losses in those parts of the system through which the total quantity of water

• Primary circuit pumps in systems with large pressure losses in the primary circuit.

• Air-conditioning systems with

– heat exchangers (fan coils) – cooling ceilings – cooling surfaces.

In systems with relatively small pressure losses in the distribution pipes.

• Two-pipe heating systems with thermostatic valves and

– dimensioned for natural circulation – small pressure losses in those parts of the system through which the total quantity of water

flows (for example boiler, heat exchanger and distribution pipe up to the first branching) or

– modified to a high differential temperature between flow pipe and return pipe (for example

district heating).

• Underfloor heating systems with thermostatic valves.

• One-pipe heating systems with thermostatic valves or pipe balancing valves.

• Primary circuit pumps in systems with small pressure losses in the primary circuit.

If you install an external controller, the pump is able to change from one constant curve to another, depending on the value of the external signal. You can also set the pump to operate according to the maximum or minimum curve, like an uncontrolled pump:

• You can use the maximum curve mode in periods in which a maximum flow is required. This operating mode is for instance suitable for hot-water priority.

• You can use the minimum curve mode in periods in which a minimum flow is required. This operating mode is for instance suitable for manual night setback if you do not want Automatic Night Setback.

In systems requiring a constant flow, independently of pressure drop. Examples:

• chillers for air-conditioning

• heating surfaces

• cooling surfaces.

In systems requiring a constant tank level, independently of the flow rate. Examples:

• process water tanks

• boiler condensate tanks.

19. Bus signal

Note

The motor enables serial communication via an RS-485 input. The communication is carried out according to the Grundfos GENIbus protocol and enables connection to a building management system or another external control system.

Via a bus signal, you can remote-set motor operating parameters, such as setpoint and operating mode. At the same time, the motor can, via the bus, provide status information about important parameters, such as actual value of control parameter, input power and fault indications.

Contact Grundfos for further information.

If you use a bus signal, the number of settings available via the Grundfos GO Remote will be reduced.

20. Priority of settings

You can always set he motor to operation at maximum speed or to stop with the Grundfos GO Remote.

If you enable two or more functions at the same time, the motor will operate according to the function with the highest priority.

Example: If, via the digital input, the motor has been set to maximum speed, the motor control panel or the Grundfos GO Remote can only set the motor to "Manual" or "Stop".

The priority of the settings appears from the table below:

23. Maintenance and service

Warnin g

Before starting work on the pump, make sure that

the power supply has been switched off for at

least 5 minutes. Make sure that the power supply

cannot be accidentally switched on.

Warnin g

Make sure that the escaping water does not

cause injury to persons or damage to the

equipment.

Warnin g If the pump is used for a liquid which is injurious

to health, it will be classified as contaminated. In such cases, the proper precautions must be taken to avoid injury to health when operating or working on the pump.

23.1 Maintenance

23.1.1 Pump

The pump is maintenance-free. If the pump is to be drained for a long period of inactivity, inject a

few drops of silicone oil on the shaft between the motor stool and the coupling. This will prevent the shaft seal faces from sticking.

23.1.2 Motor

The motor must be checked at regular intervals. It is important to keep the motor clean in order to ensure adequate ventilation. If the pump is installed in a dusty environment, clean and check the pump regularly.

23.2 Service

If Grundfos is requested to service the pump, it must be cleaned before it is returned.

If proper cleaning is not possible, all relevant information about the pumped liquid must be provided.

If the above is not fulfilled, Grundfos can refuse to accept the pump for service.

Possible costs of returning the pump are to be paid by the customer.

23.2.1 Integral shaft/coupling

TPE2 and TPE3 pumps have integral shaft/coupling. We recommend that you do not remove the motor.

If the motor has been removed, it is necessary to remove the motor stool in order to refit the motor correctly. Otherwise the shaft seal may be damaged.

23.2.2 Blanking flanges

For twin-head pumps, a blanking flange with a pump housing gasket is available. See fig. 72.

Fig. 72 Fitting the blanking flange

If one pump requires service, the blanking flange is fitted to allow the other pump to continue operating.
