Calpeda GQG 6-25 Submersible Pump With High-Power Grinder/Macerator  1.50kW - 2.00 HP - Three Phase

The Calpeda GQG6-25 is a powerful and robust submersible wastewater pump designed for demanding residential, commercial, and industrial sewage applications. Featuring an integrated high-torque grinder system, this 1.50kW, 415V three-phase unit is capable of shredding long fibres, textiles, paper, and organic matter before discharge — ensuring smooth operation and preventing blockages in narrow or pressurised discharge lines.

Constructed for longevity and reliability, the GQG6-25 includes a double mechanical shaft seal housed in an oil chamber, providing maximum protection against dry-running and seal failure. The horizontal DN32 / G1½” flanged and threaded outlet supports easy connection to pressure sewer lines and rising mains, making this pump ideal for use in modern grinder pump stations and septic systems.
