In order to ensure safe transport,

Grundfos recommends to transport the

pumps with suitable lifting tools.

Warning

The pump must not be used for the

transfer of flammable or toxic liquids.

5. Identification

5.1 Nameplates

The pump and motor nameplates are positioned on

the motor fan cover or terminal box.

The data and information on the pump nameplate

are described in the table below. See the nameplate

in fig. A on page 270.

The data and information on the motor nameplate

are described in the table below. See the nameplate

in fig. B on page 270.

6. Mechanical installation

Before installing the pump, check that the pump type

and parts are as ordered.

6.1 Installation of pump

The pump must be installed on a plane surface and

fixed so that it cannot be displaced during start-up

and operation.

The pump must be installed so that air locks are

avoided in the pump housing and pipework. Figure 1

shows the permissible pump positions.

Fig. 1 Pump positions

6.2 Pipework

It is advisable to fit isolating valves on either side of

the pump. It is thus not necessary to drain the

system if the pump needs service. If the pump is

installed above the liquid level, a non-return valve

must be fitted in the suction pipe below the liquid

level.

The pump must not be stressed by the pipework.

The pipework must be correctly sized taking due

account of the pump inlet pressure.

If the pump is installed at the lowest point of the

system, impurities and sludge may accumulate in the

pump.

Install the pipes so that air locks are avoided,

especially on the suction side of the pump.

See fig. 2.

positions on special request. See fig. 5.

Fig. 5 Terminal box positions

7. Electrical installation

Check that the mains voltage and frequency

correspond to the values on the motor nameplate.

7.1 Supply cable

In order to comply with the EN 60335-1 standard,

the supply cable must as minimum be rated for an

operating temperature of +105 °C (+221 °F).

7.2 Motor protection

Single-phase motors, 1 x 115/230 V, 60 Hz, do not

incorporate motor protection and must be connected

to a motor-protective circuit breaker which can be

manually reset. Set the motor-protective circuit

breaker according to the rated current of the motor

1/1

). See nameplate.

Other single-phase motors have built-in current-

and temperature-dependent motor protection in

accordance with IEC 60034-11 and require no further

motor protection. The motor protection is of the

TP 211 type, which reacts to both slow- and quick-

rising temperatures. The motor protection is

automatically reset.

TM04 0338 0608

Caution

Take care to avoid damaging the pump

when connecting the suction and

discharge pipes.

The torques in the table below must not

be exceeded.

Warning

The electrical connection must be

carried out in accordance with local

regulations.

Before starting work on the pump,

make sure that the electricity supply

has been switched off and that it cannot

be accidentally switched on.

Three-phase motors up to 3 kW must be connected

to a motor-protective circuit breaker which can be

manually reset. Set the motor-protective circuit

breaker according to the rated current of the motor

1/1

). See nameplate.

Motors with power ratings of 3 kW and up have built-

in thermistors (PTC). The thermistors are designed

according to DIN 44082. The motor protection is of

the TP 211 type, which reacts to both slow- and

quick-rising temperatures.

7.3 Electrical connection

Carry out the electrical connection as shown in the

diagram inside the terminal box cover.

Fig. 6 Wiring diagram

7.4 Frequency converter operation

All three-phase motors can be connected to a

frequency converter.

Depending on the frequency converter type, this may

cause increased acoustic noise from the motor.

Furthermore, it may cause the motor to be exposed

to detrimental voltage peaks.

* MG 71- and MG 80-based motors with phase

insulation are available on request.

The above disturbances, i.e. both increased acoustic

noise and detrimental voltage peaks, can be

eliminated by fitting an LC filter between the

frequency converter and the motor.

For further information, please contact the frequency

converter supplier or Grundfos.

8. Start-up

8.1 Liquid filling

1. Close the isolating valve on the discharge side of

the pump.

2. Open the isolating valve in the suction pipe

completely before starting the pump.

3. Remove the filling plug. See fig. 7.

4. Fill the pump housing and the suction pipe

completely with liquid until a steady stream of

liquid runs out of the filling hole.

5. Fit and tighten the filling plug.

6. Slowly open the discharge isolating valve while

the pump is running. This ensures venting and

pressure build-up during start-up.

Fig. 7 Plugs in the pump sleeve

8.2 Checking the direction of rotation

The motor fan cover has an installation indicator.

See fig. 8. Based on the motor cooling air, it

indicates the direction of rotation of the motor.

Before the motor is started for the first time or if the

position of the indicator has been changed, the

indicator function should be checked, for instance by

moving the indicator field with a finger.

To determine whether the direction of rotation is

correct or wrong, compare the indication with the

table below.

* To reverse the direction of rotation, switch off the

electricity supply and interchange any two of the

incoming supply wires.

TM03 8781 1008

Caution

MG 71- and MG 80-based motors have

no phase insulation* and must

therefore be protected against voltage

peaks higher than 650 V (peak value)

between the supply terminals.

Caution

Do not start the pump until it has been

filled with liquid.

Warning

The system may be under pressure,

and the escaping liquid may be

scalding hot. Care must therefore be

taken to ensure that the liquid does not

cause personal injury or damage to

other components.

Caution

The discharge valve must be opened

immediately after start-up of the pump.

Otherwise the temperature of the

pumped liquid may become too high

and cause material damage.

TM03 8774 1008

Note

If it is difficult for the pump to build up

pressure, it may be necessary to repeat

steps 1 to 6.

Note

The description below applies to three-

phase motors only.

Fig. 8 Installation indicator

The indicator can be placed in various positions on

the motor, but it must not be placed between the

cooling fins close to the screws holding the fan

cover.

The correct direction of rotation is also shown by

arrows on the motor fan cover.

9. Maintenance

The internal pump parts are maintenance-free. It is

important to keep the motor clean in order to ensure

adequate cooling of the motor. If the pump is

installed in dusty environments, it must be cleaned

and checked regularly. Take the enclosure class of

the motor into account when cleaning.

The motor has maintenance-free, greased-for-life

bearings.

9.1 Frost protection

Pumps which are not being used during periods of

frost should be drained to avoid damage.

Remove the filling and drain plugs. See fig. 7.

Do not refit the plugs until the pump is taken into

operation again.

9.2 Cleaning

Prior to a long period of inactivity, the pump must be

flushed with clean water to prevent corrosion and

deposits in the pump.

10. Service

Before returning the pump to Grundfos for service,

the safety declaration at the end of these

instructions must be filled in by authorised personnel

and attached to the pump in a visible position.

If Grundfos is requested to service the pump, it must

be ensured that the pump is free from substances

that can be injurious to health or toxic. If the pump

has been used for such substances, the pump must

be cleaned before it is returned.

If proper cleaning is not possible, all relevant

information about the chemical 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 paid by the

customer.

The safety declaration can be found at the end of these

instructions (only in English).

11. Technical data

11.1 Enclosure class

• Standard: IP55.

11.2 Sound pressure level

The sound pressure level of the pumps is lower than

70 dB(A).

11.3 Ambient temperature

* Note: Only the stainless-steel variant (EN 1.4301/

AISI 304) is suitable for pumping liquids with

temperatures above +90 °C (194 °F).

TM04 0360 1008

Warning

Before starting work on the pump,

make sure that the electricity supply

has been switched off and that it cannot

be accidentally switched on.

Caution

Before start-up after a period of

inactivity, the pump and the suction

pipe should be completely filled with

liquid. See section 8.1 Liquid filling.

11.4 Maximum system pressure and permissible liquid temperature

* At liquid temperatures below 0 °C (32 °F), higher motor outputs may be needed due to increased viscosity,

for instance if glycol has been added to the water.

** 120 °C applies only if the pump has an AQQE shaft seal.

*** CM pumps for pumping liquids at temperatures below –20 °C are available on request. Please contact

Grundfos.

11.5 Minimum inlet pressure

The minimum inlet pressure "H" in metres head

required during operation to avoid cavitation in the

pump can be calculated from the following formula:

H = p

x 10.2 – NPSH – H

– H

= Barometric pressure in bar.

(Barometric pressure can be set to 1 bar.)

In closed systems, p

indicates the

system pressure in bar.

NPSH = Net Positive Suction Head in metres head

(to be read from the NPSH curves on

pages 270 to 273 at the highest flow the

pump will be delivering).

= Friction loss in suction pipe in metres

head.

= Vapour pressure in metres head, see

fig. I, page 274.

= liquid temperature.

= Safety margin = min. 0.5 metres head.

If the calculated value of "H" is positive, the pump

can operate with a maximum suction lift of "H"

metres.

If the calculated value of "H" is negative, a minimum

suction head of "H" metres is required during

operation to avoid cavitation.

Example

= 1 bar.

Pump type: CM 3, 50 Hz.

Flow rate: 4 m

/h.

NPSH (from fig. D, page 271): 3.3 metres head.

= 3.0 metres head.

Liquid temperature: 90 °C.

(from fig. I, page 274): 7.2 metres head.

H = p

x 10.2 – NPSH – H

– H

[metres head].

H = 1 x 10.2 – 3.0 – 3.3 – 7.2 – 0.5 = –3.8 metres

head.

This means that a suction head of 3.8 metres is

required during operation.

Pressure calculated in bar: 3.8 x 0.0981 = 0.37 bar.

Pressure calculated in kPa: 3.8 x 9.81 = 37.3 kPa.

11.6 Maximum inlet pressure

The actual inlet pressure plus the pressure when the

pump is operating against a closed valve should

always be lower than the maximum system pressure.
