2. General description

Grundfos BM and BMhp booster modules are designed for
pressure boosting, liquid transfer and circulation in systems with
a high static pressure.

2.1 Pumped liquids

The pumps are suitable for pumping thin, non-explosive liquids,
not containing abrasive particles or fibres. The liquid must not
attack the pump materials chemically and mechanically.
Do not use the pumps for pumping flammable or
combustible liquids such as diesel oil, petrol or
similar liquids.

2.2 Sound pressure level

The sound pressure level of BM 4" and BM and BMhp 6" booster
modules is lower than 70 dB(A).
The sound pressure level of BM and BMhp 8" booster modules is
lower than 80 dB(A).

3. Delivery, transportation and storage

Delivery
The booster modules are supplied from the factory in proper
packing in which they should remain until they are to be installed.
The modules are ready for installation.
Transportation and storage
CAUTION
Crushing of feet
Minor or moderate personal injury

During transportation and storage, the booster modules may only
be placed in the positions shown in fig. 1.
Before storage, the booster modules must be flushed through
with clean freshwater. See section
module.
Fig. 1 Positional requirements
If the module has been stored for more than one
year, the motor liquid must be checked and refilled, if
required.
Motors of standard modules are factory-filled with a Grundfos
motor liquid, SML-3, which is frost-proof down to -20 °C.
Motors of modules in special versions may be filled with
demineralised water, that is not frost-proof.

3.1 Frost protection

If the module has to be stored, it must be stored on a frost-free
location, or it must be ensured that the motor liquid is frost-proof.
