PUMP

GRUNDFOS SP submersible pumps are designed specifically for borehole supply applications. They are of multistage centrifugal impeller design and all parts are made from stainless steel with water lubricated rubber bearings. A submersible motor is fitted beneath the pump and suction is effected through a strainer between the pump and motor.
Standard pumps are designed for the pumping of non-aggressive water. An 'N' version is available for applications requiring a higher degree of corrosion resistance.

MOTOR

The pump is coupled to a 2-pole asynchronous sealed liquid cooled Grundfos motor constructed of stainless steel. All motors require a remote starter and if there is risk of unstable supply voltage. An additional quick tripping control relay is recommended.Note that due to low starting torques of submersible motors it is recommended that DOL starters are used for all motor sizes.
