Characteristics

Slimline submersible borehole pumps suitable for 4"or large deep wells. Manufactured from corrosion abrasion resistant materials. Close coupled to NEMA standard submersible motor. Designed for flow rates up to 28m/h& head up to 325 meters.

Construction characteristics

PUMP

abrasion-resistant construction. The front wear plate, combined

with the floating impellers, ensures optimum resistance to abrasion

The upper and lower supports are made of precision-cast stain

less steel, ensuring resistance to corrosion, durability and a sturdy

coupling to the motor.

The hexagonal pump shaft guarantees an effective impeller driving

A stainless steel non-return valve is fitted in the discharge to

prevent any back flow of water and alleviate any water hammer

to the pump, thus safeguarding impellers and diffusers

The 4ST series pumps can be coupled 4SD( M)motors.
