uninstallation much easier.
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
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
