Energy Saving Sand And Gravel Pump , Hydraulic Dredge Pump Convenient Maintenance

High chrome alloy gravel suction pump parts of A05, A49, Cr26,Cr27

Pump introduction 

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.

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

600WN to 1000WN uses helical casing L rubber seal which is made of 3 pieces of L seal ring and one special thread shaft sleeve.

Turning

700WN to 1000WN can be equipped with turning to change rotating directions.
