BM, BMBBooster modules 4”, 6”, and 8”60 Hz and 50 Hz

ConstructionGrundfos modified standard submersible pumps are used for BM and BMB booster modules. Pump and motor are centered in a stainless steel sleeve. Both sleeve ends can be connected to the piping by means of victaulic couplings.

Sleeve of 4”, 6”, and 8” modules is supplied with straight pipe inlet and outlet. The 4” size isalso available with 90° bends at the suction and discharge ends.

BM and BMB pumps have an asynchronous sub-mersible squirrel-cage motor of the canned type with water-lubricated bearings.
