Pump Introduction
WA series are cantilevered, horizontal, natural rubber or hard metal lined centrifugal slurry pumps.
They are designed for handling abrasive, high density slurries in the metallurgical, mining, coal, power, building material and other industry department.
Typical Applications
SAG mill discharge, ball mill discharge, Rod mil discharge, Ni acid slurry, coarse sand, coarse tailings, phosphate matrix, minerals concentrate, heavy media, sugar beet, dredging, bottom/fly ash, lime grinding,oil sands, mineral sands, fine tailings, slag granulation, phosphoric acid, coal, flotation, process chemical,
pulp and paper, FGD, cyclone feed, etc.
Features
The frame plate for WA series pumps has interchangeable hard metal or pressure moulded elastomer liners.The impellers are made of hard metal or pressure moulded elastomer liners.The shaft seals for WA series can be packing seal, centrifugal seal or mechanical seal.The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight
positions to suit installations and applications. There are many drive modes for option, such as V-belt,flexible coupling, gearbox, hydraulic coupler variable frequency, silicon controlled speed, etc. Among them,
the flexible shaft coupling drive and V-belt feature of low cost and easy installation.

Construction Design
CasingSplit casing halves of cast or ductile ironcontain the wear liners and provide highoperation pressure capabilities.
Interchangeable hard metal and moulded
elastomer liners
ImpellerThe impeller may be either mouldedelastomer or hard metal. Deep sidesealing vanes relieve seal pressure andminimize recirculation.Cast-in impeller threads are better suitedfor slurries.
Mating faces in hard metal liners are tapered to allow positivealignment during assembly and allow components to be easilyremoved for replacement.
