6. Applications
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
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.
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.
7.5 Operating pressure/test pressure
The pressure test has been made with water containing
anti-corrosive additives at a temperature of +68 °F (+20 °C).
Warning
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.
Note
Note
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.

7.6 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
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.
Fig. 3 Derating of motor output power (P2) in relation to
altitude above sea level
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.
Caution
The motor must not be installed more than
6562 ft (2000 m) above sea level.

8. Mechanical installation
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.
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
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
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
pump with the motor shaft in horizontal position. See fig. 6.
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.
Fig. 8 Correct pipework on the suction side of 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.
Warning
When pumping hot or cold liquids, make sure
that persons cannot accidentally come into
contact with hot or cold surfaces.
Note
Note
In order to maintain the UL mark, additional
installation procedures must be followed.

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

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.
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
Pump settings can be made by means of the following user
interfaces:
Control panels
• Standard control panel.
See section 12. Standard control panel.
• Advanced control panel.
See section 13. Advanced control panel.
Remote controls
• Grundfos GO Remote.
See section 14. Grundfos GO Remote.
If you switch-off the power supply to the pump, the settings will be
stored.
Factory settings
TPE2 (D) pumps have been factory-set to constant-curve control
mode. See section 12.1.2 Pump in constant-curve control mode.
The setpoint value corresponds to 100 %, of maximum pump
performance. See data booklet or WebCAPS.
TPE3 (D) pumps have been factory-set to AUTOADAPT control
mode. See section 15.4.1 AUTOADAPT.
TM05 7922 1613
Warning
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.

12.1.1 Pump in differential-pressure control mode
The following example applies to a pump in an application where
a pressure sensor gives a feedback to the pump. If you retrofit the
sensor to the pump, you must set it up manually as the pump
does not automatically register a connected sensor.
Figure 28 shows that the light fields 5 and 6 are activated,
indicating a desired setpoint of 4.3 psi (3 m) with a sensor
measuring range from 0 to 8.5 psi (0 to 6 m). The setting range is
equal to the sensor measuring range.
