A cutter pump is only as good as its blade. GNWQ pumps use a high-hardness alloy cutting head rated at Rockwell 48 HRC and above — noticeably harder than the ordinary steel found in many competing pumps — so it slices fibre and debris cleanly instead of merely tearing at it.
For abrasive or especially tough duty, the cutting material can be customised up to 65 HRC on request. Sharp, hard blades mean solids are shredded on intake and the impeller downstream never sees a clog.
Why hardness matters
A dull or soft blade rounds off quickly, cutting worsens, and clogging returns. A 48–65 HRC alloy edge holds its sharpness far longer, which keeps performance steady and service intervals long.
Applications: tough fibrous waste, abrasive sewage, slaughterhouse and farm effluent, textile and paper waste, municipal drainage

GNWQ Cutting Submersible Sewage PumpThe details that decide how long a sewage pump lasts are easy to overlook on a spec sheet. GNWQ pumps are specified to survive: bolts and lifting rings in SUS304 stainless steel (not ordinary steel th…
GNWQ Cutting Submersible Sewage PumpTwo claims get made about a lot of sewage pumps: full head and no clogging. The GNWQ range actually delivers both. Its hydraulics are tuned so the pump reaches its rated head across the duty range — a…
GNWQ Cutting Submersible Sewage PumpOne practical advantage of the GNWQ design is its easy-remove cutter disc. Instead of scrapping the pump when the cutting parts wear, you simply swap the disc — and you can fit a different disc to sui…
