2. General description
Grundfos BMP pumps are piston pumps, i.e. the flow is
proportional 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.
2.1 Handling
The motor lifting eyes must always be used for lifting the entire
pump.
Note: The pump may not be in balance.
3. Applications
3.1 Pumped liquids
Thin, non-explosive liquids, not containing solid particles or
fibres. The liquid must not attack the pump materials chemically.
In case of doubt, please contact Grundfos.
The pump must never operate with water/liquid containing
substances which would remove the surface tension, e.g. soap.
If this type of detergent is used for cleaning the system, the
water/liquid must be led around the pump via a bypass.
Note: The liquid to be pumped must be prefiltered to maximum
10 microns (abs.

10
> 5000).

Warning
Prior to installation, read these installation and
operating instructions. Installation and operation
must comply with local regulations and accepted
codes of good practice.
Warning
If these safety instructions are not observed, it may
result in personal injury.
Warning
The pump must not be used for the pumping of
inflammable liquids such as diesel oil, petrol or
similar liquids.
Pump type Recommended pumped liquids
BMP
• Raw water
• potable water
• groundwater
• surface water (lakes and rivers).
BMP-N
• Softened water (cation exchange)
