AIER® WN Dredge Pump

Construction

200WN to 500WN dredge pumps are of single casing, single stage cantilevered horizontal centrifugal pumps. Two types of coupling with gear box: frame and pump box.

600WN to 1000WN dredge pumps are of double casings, single stage cantilevered centrifugal pumps. These pumps are equipped with frame and lubrication is force thin oil. The design of double casing the pump working till the volute liner almost worn down and guarantee no leakage when volute liner is worn down.

Easy Uninstallation & Convenient Maintenance

WN dredge pump is of front uninstallation construction to make uninstall easily and convenient maintenance. And special tools are equipped for uninstalling the parts.

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

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

Shaft Seal types of 200WN to 500WN: Mechanical seal, packing, or combination of mechanical and packing
