Pumpmaster GPA-Series Submersible Sewage Grinder Pump with Float 

The Pumpmaster GPA Series Submersible Sewage Grinder Pumps are heavy-duty, industrial-quality wastewater pumps engineered for demanding sewage and wastewater applications where solids and fibrous materials are present. Designed to grind and macerate waste into a fine slurry before discharge, the GPA Series is suited to installations where gravity-fed drainage systems are impractical or where downstream clogging must be minimised.

Featuring an advanced integrated grinding mechanism with chromium-molybdenum alloy steel fixed and rotating blades, the GPA Series delivers over 80,000 shredding actions per minute, providing superior solids reduction and smooth pumping performance. 

These pumps are built with a rugged, corrosion-resistant stainless steel motor casing and a robust cast-iron impeller and housing, ensuring long service life in corrosive sewage environments. A double mechanical seal plus shaft seal system and built-in motor protection with reset safeguard the motor against ingress and overload, enhancing reliability and peace of mind.
