Product Overview

A deep collection pit under a villa or small building creates a specific need: not much flow, but a serious vertical lift through a narrow line — and no tolerance for clogs, because reaching the pump means going down into the pit.

The 50GNWQ25-22-4 is tuned for that: a strong 22 m of head at 25 m³/h from 4 kW, all through a 50 mm outlet. It’s one of the highest-head pumps in the small-bore class, which is what lets it clear a deep pit to a distant or elevated main. The 48 HRC alloy cutter is essential here — a 50 mm riser this tall is merciless on anything unshredded — and the heat-treated 3Cr13 impeller holds its edge and won’t rust between cycles.

When you need maximum lift from a 50 mm pump, this is the one to look at. It’s a stocked size — ask us for a shipping date at sales@haquanpump.com.
