Product Introduction of dredge pump
WN Series submerged dredge pump is a new type of sludge pump researched & manufactured by SHIZA PUMP aiming at rivers and seas out of repair.WN pump is a single-stage single suction cantilever horizontal centrifugal pump with advantages of light weight, good wear-resistan, super dredging performance, perfectly suited for the dredge on the whole construction, high multiple economy benefits, etc.. It throughout meets requirements of the dredge to dredging pumps.
The good cavitation performance of the WN series of mud pumps ensures that the mud pump has a high suction capacity while achieving greater dredging and higher suction concentrations.
The width of the WN series mud pump impeller is large, and the good passing ability of the mud pump itself is a good guarantee for the performance range of the dredger. It can continuously pump gravel or high-viscosity mud without clogging.
The impeller, sheath and front and rear guard plates of the WN series mud pump are made of strong anti-wear alloy cast iron with a hardness of not less than 58HRC. They have strong impact resistance and high anti-abrasion performance.
Features
1. huge capacity, very high head and long horizontal discharge distance.
2. high chrome alloy material, suitable for suck stones and rock in water.
3. suitalbe for many kinds of mining, especially for sand mining in dredging work.
4. it can be submersible , then the dredger want to suck the sand from 30-60meter deep in the sea.
5.simple structure, longer life . special seal type without leakage.
