150GNWQ120-10-7.5 Low-Head Cutter Pump for Lagoons

Not every big job needs high pressure. Transferring water between lagoon cells, emptying a stabilisation pond, or shifting flow along an open drain is about moving a large volume a short lift — and doing it through water that’s full of weed, rag and floating debris.

The 150GNWQ120-10-7.5 is tuned for exactly that: 120 m³/h at a deliberately low 10 m head, 7.5 kW, 150 mm outlet. The wide bore and the 48 HRC alloy cutter let it swallow and shred the stringy debris that open water always carries — reeds, plastic, fibrous sludge — instead of blocking on it. The 3Cr13 impeller is heat-treated for the grit that comes with pond and canal work.

Choosing between this and a high-head model comes down to your discharge line: if you’re moving a lot of dirty water a short way, low-head-high-flow like this is the efficient choice; if you’re lifting it steeply, look at the 65- or 100 mm high-head models instead.
