Lowara : GS Series 4” Borehole Pumps

Multi-stage centrifugal submersible pumps for clean water in 4” wells

 High content of AISI 304 stainless steel. The floating impeller design ensures an excellent resistance to wear.

The upper and lower supports are made of precision-cast stainless steel ensuring resistance to corrosion, strength and rigid coupling to the motor. The non-return valve is integrated in the head to support the weight of the column of water and protect against water hammer, thus safeguarding impellers and diffusers. Can also operate in a horizontal position.
