A factory canteen feeds hundreds of people in a short window, and the drain pit takes the consequences: food scraps, disposable packaging, gloves, and cleaning cloths, all arriving at once at the lunch rush. A basic pit pump can’t keep pace and clogs at the worst possible time.
The 50GNWQ20-15-2.2 is right-sized for a single canteen: 20 m³/h at 15 m head, 2.2 kW, 50 mm outlet. The 48 HRC alloy cutter shreds the packaging and fibrous waste; the heat-treated 3Cr13 impeller handles the greasy, gritty stream without wearing out.
A question plant engineers often ask: does it need three-phase power? This size is available in single-phase 220 V as well as 380 V, so it suits a small canteen supply or a full plant — just tell us which you have. We keep it stocked for quick delivery: sales@haquanpump.com.
