Non-Clog Sewage Pump (KWP)

Industrial valves and fittings dispatch fast — wear parts and complete machines quoted on request.

Sewage & Wastewater Pumps

Single-casing non-clog pumps for sewage, fibrous wastewater and solids-bearing process water, with open, semi-open, closed or free-flow impellers. Images are representative renderings of each series; finish, accessories and nameplate follow the confirmed drawing.

Horizontal axial-suction, single-stage, single-suction, single-casing pump. The impeller is offered in open, semi-open, closed and free-flow form, so the same casing covers clean-ish water transfer, fibrous sewage and solids-bearing process water — the free-flow version passes large solids without a chopper. Used on sewage treatment projects, breweries, power plants, petrochemical plants, mines, paper mills and construction sites. Outlet DN40–DN500, flow 10–3,000 m³/h, head 5–80 m, two speed families (1450 and 960 r/min) so a lower-speed build can be selected where wear life matters more than head. Wetted parts are wear-resistant metal only in this series.

Four impeller styles in one casing

The casing stays the same and the impeller changes: open, semi-open, closed or free flow. Open and semi-open pass fibrous and solids-bearing water; closed is the efficient choice for cleaner water; free flow passes large solids without a chopper.

That is the first decision on this series. Choosing a closed impeller for a rag-laden duty is the usual reason a sewage pump blocks, and choosing free flow for clean water gives away efficiency for nothing.

Two speed families, two wear lives

The series is published at 1450 and 960 r/min. The slower build gives lower wear and lower NPSH requirement at the same duty point, at the cost of a larger machine — which is the trade to make where maintenance access is difficult.

Outlet DN40–DN500, flow 10–3,000 m³/h, head 5–80 m. Wetted parts are wear-resistant metal in this series.
