English (GB)

6.1 Pumped liquids

The pump is suitable for thin, clean, non-aggressive

and non-flammable liquids, not containing solid

particles or fibres that may attack the pump

mechanically or chemically.

Examples:

• Central heating system water. The water must

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 have

the following effects:

• 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 contains mineral or synthetic oils or

chemicals or if other liquids than water are pumped,

chose the O-rings accordingly.

7. 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, PN 6/10, use washers as shown in fig.

Fig. 3 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 300 mm is required above the motor.

See fig. 4.

Fig. 4 Required clearance above the motor

WARNING

Contact with hazardous liquids

Death or serious personal injury

- If the pump is used for a liquid which is

injurious to health, it will be classified as

contaminated. In such cases, take

proper precautions to avoid injury to

health when operating or working on the

pump.

- Wear personal protection equipment.

WARNING

Hot or cold surface

Death or serious personal injury

- Make sure that no one can accidentally

come into contact with hot or cold

surfaces.

In order to maintain the UL mark,

additional requirements apply to the

equipment. See page 84.

TM01 0683 1997

The motor must never fall below the

horizontal plane.

TM05 7916 1613

Installation

Washer Pump

300 mm

English (GB)

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. 5.

The automatic air vent is not supplied with the pump.

Fig. 5 Automatic air vent

If the liquid temperature falls below the ambient

temperature, condensation may form in the motor

during standstill. In this case, make sure that one of

the drain holes in the motor flange is open and points

downwards. See fig. 6.

Fig. 6 Drain hole in motor flange

If twin-head pumps are used for pumping liquids with

a temperature below 0 °C (32 °F), 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. 5.

7.1 Pipes

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 pipes.

The inlet and outlet 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 inlet side of the pump. See fig. 7.

Fig. 7 Correct pipes on the inlet side of the

pump

If there is any risk of the pump running against a

closed outlet valve, ensure a minimum liquid flow

through the pump by connecting a bypass or a drain

to the outlet pipe. The drain can for instance be

connected to a tank. A minimum flow rate of 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.

TM05 7983 1713TM05 7917 1613

Observe the conditions in section

10. Operating conditions.

TM00 2263 0195

The pump must not run against a closed

outlet valve as this will cause an increase

in temperature or formation of steam in the

pump, which may cause damage to the

pump.

English (GB)

7.2 Terminal box positions

You can turn the terminal box to any position.

Change the terminal box position as follows:

1. Loosen the clamp securing the pump head to the

pump housing. See fig. 8.

Fig. 8 Clamp (A)

2. Turn the pump head to the required position.

3. Check the following before you tighten the clamp:

– The contact face of the pump housing and that

of the pump head must be in full contact.

– The clamp must be positioned correctly in the

flange recess of both the pump head and the

pump housing. See fig. 11.

Torque: 8 Nm (± 1 Nm).

pump.

Fig. 12 Insulation of TPE2, TPE3 pumps

7.6 Frost protection

Drain pumps which are not being used during

periods of frost to avoid damage.

7.7 Cable entries

See the size of the cable entries in section 33. Other

technical data.

7.8 Ensuring motor cooling

Leave at least 50 mm between the end of the fan

cover and a wall or other fixed objects. See fig. 13.

Fig. 13 Minimum distance, D, from the motor to

a wall or other fixed objects

7.9 Outdoor installation

If you install the motor outdoors, provide the motor

with a cover and open the drain holes to avoid

condensation on the electronic components. See fig.

14.

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 humidity,

we recommend that you connect the motor

permanently to the mains supply and activate the

built-in standstill heating function. See section

16.25 "Standstill heating".

Fig. 14 Examples of covers, not supplied by

Grundfos

Do not insulate the motor stool as this will

trap any vapour escaping from the shaft

seal, thus causing corrosion. Covering the

motor stool with insulation will also make

inspection and service difficult.
