Standard four-head trapezoid thread connection between impeller and shaft can transfer powerful torsion and be convenient to uninstall. Impeller uninstall ring at shaft sleeve side also make the impeller uninstallation much easier.

Good Performance

Good NPSH can not only guarantee suction but also make deep dredge and high allowable suction density. Minimum NPSH: 4m.

With wide impeller passage, pump can continuously pump gravel or high plastic clay without clogging. Max allow particle size: 350mm.

Performance curves descend obviously to make pumps adopt pipeline distance changes.

By changing the impeller diameter or impeller rotating speed, it can easily change the discharge with the same flow rate.


Material of wet parts is high wear resistant high chrome alloy.

Considering the maintenance, wear resistant parts are nearly of the same wear life to reduce maintenance & interchange costs.

Low Hydraulic loss, High efficiency, Energy Saving

Efficiency of WN is 2 or 3 percentage higher than other common pumps.

Reliable Shaft Seal, No leakage
