BWSP 2– Submersible Borehole Pump

Pump: BWSP 2 submersible pumps are designed specifically for borehole applica ons. They are of mul stage centrifugal impeller
design. All parts are made from stainless steel (AISI 304) that ensures high corrosive resistance. This pump carries drinking water
approvals. Standard pumps are designed for the pumping of non-aggressive water. An ‘SP 2N’ version is available for applica ons
requiring a higher degree of corrosion resistance. Pump has sand shield and water-lubricated rubber bearings. Suc on is through a
strainer between the pump and motor.

MOTOR: The pump is coupled to a sealed, liquid cooled 2-pole asynchronous squirrel-cage Grundfos motor constructed of stainless steel.
The motor is fitted beneath the pump. Both single-phase and three-phase motors require a DOL control panel starter. If unstable power
supply is likely, addiTonal quick tripping control relays are recommended.
