DS 30



DAYLIFF DS borehole pumps 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.

MOTOR
The pump is coupled to a 2-pole asynchronous sealed liquid cooled motor constructed stainless steel.  The motor requires a remote starter and if unstable supply voltage is likely, an additional quick tripling control relay is recommended.  Note that due to low starting torques of submersible motors, it is recommended that DOL starters are used.
