Calpeda GQSM 50 Submersible Pump with Float Switch, 10m Cable and Incorporated Capacitor

The Calpeda GQSM 50 Series is a heavy-duty, high-performance submersible sewage and drainage pump designed for domestic, commercial, and industrial wastewater management. Featuring a free-flow vortex impeller and rugged cast iron construction, the GQSM 50 handles dirty water with suspended solids up to 50 mm, making it an ideal solution for septic systems, stormwater pits, greywater transfer, and tank drainage.

This single-phase 240V model is equipped with a built-in automatic float switch, thermal protection, and an integrated capacitor for safe, hands-free operation. The double mechanical shaft seal, housed in an oil-filled chamber, provides superior protection against dry-running, ensuring long service life in continuous submersion environments.
