Put a GNWQ cutter pump next to a conventional sewage pump on the same fibrous flow and the difference shows within hours. The conventional pump’s open impeller starts collecting rag and fibre; its efficiency falls steadily, and even stopping to back-flush only recovers it for a while before the decline continues.
The GNWQ shreds the same waste on intake with its hard alloy cutter, so nothing accumulates. Its efficiency holds flat and it keeps delivering full head. Add the SUS304 hardware, motor protection and replaceable cutter disc, and it’s not just more reliable — it lasts longer and costs less to run over its life.
Applications: fibrous municipal sewage, industrial wastewater, farm effluent, continuous-duty stations, clog-prone lift pits
