Model: 65GNWQ30-17-3S
The 65GNWQ30-17-3S is an SS304 cutter sewage pump for hospitals, hotels and labs — corrosion-resistant, cleanable, and able to shred the wipes and dressings that clog these drains. 30 m³/h, 17 m, 3 kW…

Hospitals, hotels and laboratories produce a difficult kind of sewage: not high volume, but full of things that both block pumps and sometimes chemically attack them — surgical wipes, dressings, gloves, plus disinfectants and mild reagents in the wastewater.
The 65GNWQ30-17-3S is built for that setting. It’s precision-cast SS304, so cleaning agents and mild chemistry don’t eat the pump the way they would cast iron, and the smooth stainless surfaces are easier to keep hygienic. The 48 HRC alloy cutter handles the solids — shredding the stringy, fibrous waste these facilities generate so a compact 65 mm line stays open.
At 30 m³/h and 17 m head from a 3 kW motor, it’s sized for a building’s collection pit rather than a municipal main — the right duty point for a hospital wing, a hotel’s lower levels, or a lab block.
