Borehole pumps for 4” wells.
50 Hz version: Delivery up to 21 m3/h - Head up to 340 m.
Abrasion-resistant construction: The front wear plate combined with the polycarbonate floating impellers ensure optimum resistance to wear (maximum permissible quantity of sand 150 g/m3). The stainless steel structure of the pump ensures high resistance to corrosion, robustness and long-lasting performance. All the pumps can be coupled to 4” motors NEMA Std. Applications.
The upper and lower supports are made of precision-cast stainless 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 backflow of water and alleviate any water hammer to the pump, thus safeguarding impellers and diffusers. The GS series pumps can be coupled to either the 4OS or L4C motors.
