Single Casing Hard Metal 450WN Sand Pumps Used in River Dredging
Introduction:
Type WN of SME are new mud pumps are single casing sand pumps, designed for river or lake or sea dredging and sand excavation.
WN Dredging Pumps are widely used and have been a critical part in dredgers, either cutter suction type or hopper type.
Standard features • Optional rotation – Right or left hand rotation • Optional discharge positions • Suction adapter with clean out • Three and four vane impellers available • Amor-lok seal on the side liners for • metal to metal fit • Knock out ring for easy impeller removal • Wide range of alloys for pump wear parts • Over size bearings and shaft for longer life • Cantilevered design • Less shaft deflection – Better packing and bearing life
A dredge pump is the heart of what makes a hydraulic dredge function. A dredge pump creats the vacuum for sucking material from bodies of water and provides the flow for transferring the material through a pipeline to its disposal location.
