Some jobs are just brutal on a pump: a flooded construction site, a storm-overwhelmed drain, a lagoon that has to come down fast. The water is filthy, full of debris, and there’s a lot of it. Under-size the pump and you’re there all night; use a plain non-clog and it jams on the first tangle of tie-wire and plastic sheeting.
The 150GNWQ180-20-18.5 is built for the volume-and-abuse end of the range: 180 m³/h at 20 m head from an 18.5 kW motor through a big 150 mm outlet. The alloy cutter chews through the mixed rubbish that site water carries, and the heavy cast-iron build takes the rough handling that comes with temporary drainage.
One caution we always pass on: keep it about 25 cm off the bottom and out of the stones and steel off-cuts — the cutter shreds fibre and plastic all day, but it isn’t meant to eat nails.
