Calpeda GQVM 50 Submersible Pump with Float Switch, 10m Cable & Thermal Capacitor

The Calpeda GQVM 50 Series is a powerful and reliable range of submersible sewage and drainage pumps designed for tough applications in both domestic and industrial environments. Engineered with a free-flow vortex impeller and a cast iron pump casing, this pump efficiently handles dirty water and wastewater containing soft solids up to 50 mm in diameter — ideal for applications involving stormwater, septic pits, and greywater transfer.

Fitted with a single-phase 230V motor, built-in float switch, and thermal overload protection, the GQVM 50 offers automatic operation and long-term reliability. Its double mechanical shaft seal, housed in an oil-filled chamber, provides superior protection against dry-running, extending the life of the pump in continuous submersion environments.
