450WN Hard Rock Dredging Pumps , Big Suction Sand Dredging Pump
Introduction:
Type WN are new mud 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.
