GS submersible motor pumps for 4″

The pumps of the GS series are designed for the reliable pumping of clean water from deep wells and water supply systems.

Wear-resistant construction: A front balancing disc and floating impellers ensure high abrasion resistance and long service life. An integrated check valve protects impellers and diffusers from pressure surges, as relief occurs directly in the pump head. The NEMA coupling is made of corrosion-resistant stainless steel.
