GNWQ Submersible Cutter Sewage Pump — Non-Clog Chopper Pump for Fibrous Wastewater

PRODUCT OVERVIEW
The GNWQ series submersible cutter sewage pump is engineered to handle the toughest wastewater — sewage loaded with rags, fibre, plastic, gloves and stringy solids that clog ordinary pumps. A hardened cutting impeller shreds these solids before they reach the volute, ensuring continuous, clog-free operation and long service life. Fully submersible for quiet, space-saving installation directly in the sump or pit.
