Mud, sewage and drainage pumps: comparing the catalog

The supplier separates mud, sewage and drainage pumps into different series. The naming is a useful starting point; the selected model still needs to match the actual liquid and operating conditions.

Mud and slurry range

The catalog lists 2-inch QGZ50-42-30, 3-inch QGZ80-80-28 and 4-inch QGZ100-110-30 models. Listed solids diameters are 20 mm, 27 mm and 27 mm respectively. Send the particle size and media description for confirmation.

Sewage range

The 2- to 4-inch sewage family provides another set of flow and head combinations. Its description includes aluminum alloy housing, a cast iron impeller and silicon carbide mechanical seals.

Large-bore drainage range

The drainage table lists QGZ150-200-30, QGZ200-240-28 and QGZ200-300-20. Their nominal maximum flows are 200, 240 and 300 m³/h. The catalog lists 38 mm solids diameter for this range.

Build a useful inquiry

Describe the liquid, particle size, desired flow and head, duty duration, drive and delivery destination. Ask for the pump curve and detailed materials for your selected model.
