Retrofits come with a constraint new-builds don’t: the pipework is already in the wall. If a building was plumbed with a 50 mm sewage riser and the old pump has died, you need a replacement that fits that bore but still develops enough head to reach the top of the run — often a taller lift than the original ever handled well.
The 50GNWQ15-20-3 is made for that situation: a full 20 m of head at 15 m³/h from 3 kW, all through a 50 mm outlet. It lets you keep the existing riser instead of tearing open walls to fit a bigger line. And because it’s a cutter, it solves the reason the old pump probably failed — the 48 HRC alloy disc shreds the wipes and cloth that clog a narrow 50 mm pipe, while the 3Cr13 impeller holds the pressure to the top.
