Model: 200GNWQ250-15-18.5
The 200GNWQ250-15-18.5 moves 250 m³/h at 15 m head through a 200 mm outlet — an 18.5 kW cutter pump for ports, terminals and large industrial drainage.

Ports, terminals and big industrial sites generate drainage at a scale where a stoppage is expensive fast — large collection pits, continuous flow, and a debris mix of packaging, dunnage waste, rag and whatever the site handles. At this size you want capacity and a cutter that can keep the pit clear around the clock.
The 200GNWQ250-15-18.5 is a heavy-duty answer: 250 m³/h at 15 m head, 18.5 kW, 200 mm outlet, on the robust HT200/HT250 cast-iron build. The 48 HRC alloy cutter reduces the bulky solids on intake so the large 3Cr13 impeller passes them without jamming, and the detachable cutter disc means field servicing doesn’t require pulling the whole pump from a deep well.
For projects at this scale, tell us the flow, head and duty pattern and we’ll confirm the pump and lead time — stock varies on the largest frames. sales@haquanpump.com
