DS 95-12 Download datasheet

DAYLIFF DS 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.

MOTOR
The pump is coupled to a sealed liquid cooled 2-pole asynchronous squirrel cage motor constructed from stainless steel. The motor requires a remote starter and if unstable supply voltage is likely, 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.

Enclosure Class: IP68
Insulation Class: F
Voltage: 3x415V
Speed: 2900rpm

OPERATING CONDITIONS
Pumped Liquid: Thin, clean chemically non-aggressive liquids without solid particles or fibres.
Max. Liquid Temperature: +30°C
Max. Water Depth: 600m
Min. Borehole Diameter: 200mm - 6" motor, 254mm - 8" motor (DS 95-10 and DS 95-12)

PUMP DATA

E* = Maximum diameter of the pump inclusive of cable guard and motor
