GNWQ Spiral Cutter Impeller – Alloy, Anti-Clog Backward Tilt

The heart of every GNWQ pump is its spiral cutter impeller, cast from hard alloy. Two design details make it clog-proof. First, a unique backward tilt angle on the vanes stops long fibre from wrapping around the hub. Second, as the impeller spins, rags are forced into a spiral release groove, peel off the impeller into the volute, and are pumped straight out.

GNWQ Cutting Submersible Sewage Pump Impeller

That is why a GNWQ keeps running on sewage full of hair, straw, cloth and wet wipes, where an ordinary open impeller would bind up within minutes. The alloy also resists wear and rust, so the cutting edge stays sharp and the pump lasts.

Applications: fibrous sewage, rag and cloth-laden effluent, hair and animal fur, straw and organic waste, municipal and farm wastewater
