Calpeda GQRM 10 Single Impeller Submersible Drainage & Sewage Pump with Float - Single Phase

The Calpeda GQRM 10 Series is a reliable and high-performance submersible pump range designed for the drainage of clean or slightly contaminated water, as well as light sewage applications. Built with an open impeller for enhanced solids handling (up to 10mm) and a vertical discharge outlet, these pumps offer excellent flow rates in a compact and rugged form factor.

Engineered from corrosion-resistant chrome-nickel stainless steel and cast iron, each GQRM 10 model comes pre-fitted with an automatic float switch, allowing hands-free operation based on water level. The double mechanical shaft seal with interposed oil chamber ensures superior motor protection, even during dry-run conditions — making this series ideal for continuous or intermittent duty.
