Pump: BWSP 9 submersible pumps are designed specifically for borehole applications. They are of multi 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 applications
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.
Enclosure Class: IP68 Speed: 2900 rpm
MOTOR: The pump is coupled to a sealed, liquid cooled 2-pole asynchronous squirrel-cage SS 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, additional quick tripping control relays are recommended.
OPERATING CONDITIONS
Pumped Liquid: Thin, clean, chemically non-aggressive liquids without solid par cles or fibres. Max Liquid Temperature: +40 degrees C.
Max Water Depth: Up to 1.5 kW 1ph and 2.2 kW 3 ph -150 m, 2.2 kW 1ph and 3 kW 3 ph- 600 m
Minimum Borehole Diameter: 110mm (4”motor), 152mm (6” motor)
