Prior to installation, read these installation and oper-
ating instructions. Installation and operation must
comply with local regulations and accepted codes of
good practice.
1. General description
Grundfos BMP pumps are piston pumps, i.e. the flow is propor-
tional to the motor speed. The pressure is equal to the counter
pressure. Consequently, it is important that the maximum pump
pressure is not exceeded.
BMP pumps are supplied from the factory in boxes in which they
should remain until they are to be installed. The pumps are ready
for installation.
1.1 Handling
The motor lifting eyes must always be used for lifting the entire
pump.
Note: The pump may not be in balance.
2. Applications
2.1 Pumped liquids
Thin, non-explosive liquids, not containing solid particles or fi-
bres. The liquid must not attack the pump materials chemically.
In case of doubt, please contact Grundfos.
The pump must not be used for the pumping of in-
flammable liquids such as diesel oil, petrol or similar
liquids.
6
The pump must never operate with water/liquid containing sub-
stances which would remove the surface tension, e.g. soap.

If this type of detergent is used for cleaning the system, the wa-
6
ter/liquid must be led around the pump via a bypass.

3. Preparation
8
Before installation, the following checks should be made:
8
1. Transport damages
8
Make sure that the pump has not been damaged during trans-
8
portation.
8
2. Pump type
8
Check that the type designation corresponds to order, see
8
pump nameplate.
8
3. Electricity supply
8
Check that the supply voltage and frequency correspond to
9
the values stated on the motor nameplate and frequency con-
9
verter nameplate, if any.

See motor and pump nameplates.
4.1 Sound pressure level
The table below indicates the sound pressure level in dB(A)
measured in a reverberation room at a distance of 1 metre from
the pump. The anechoic noise level is calculated by subtracting
3 dB(A) from the stated values.
