AIER® WL Light Dudy Slurry Pump

WL series pumps operate in high speed with small volumes to save floor area. The frame plates have changeable, wear resistant metal liners and the impellers are made of wear resistant metal.

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, bottom/fly ash, oil sands, mineral sands, fine tailings, slag granulation, phosphoric acid, coal, flotation, process chemical, pulp and paper, FGD, cyclone feed, waste water, plant water supply, etc.

Features

The frame plate are made of wear resistant hard metal liners.

The impellers are made of hard metal.

The shaft seals 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

WL Slurry Pump

Casing

Split casing halves of cast or ductile iron contain the wear liners and provide high operation pressure capabilities.

Interchangeable hard metal and moulded elastomer liners

Impeller

The impeller may be either moulded elastomer or hard metal. Deep side sealing vanes relieve seal pressure and minimize recirculation.

Cast-in impeller threads are better suited for slurries.

Mating faces in hard metal liners are tapered to allow positive alignment during assembly and allow components to be easily removed for replacement.

Transmission Module Design

Large diameter pump shaft, cylindrical

Construction of heavy load, metric bearing using oil lubrication or grease lubrication; opened in serial, the construction features of small volume and high reliability.

Shaft Bearing Assembly

A large diameter shaft with a short overhang minimizes deflection and vibration.

Heavy duty roller bearings are housed in a removable bearing cartridge.

Pump Base

Fasten the pump in the base with a minimum number of bolts and adjust impeller in a convenient position below the bearing housing.

Water proof cover prevents leakage water from flying.

Protection cover prevents leakage water from the bearing bracket.

GRJ Mechanical Seal

GRG type is used for liquid which is not allowed diluted.

HRJ Mechanical Seal

HRJ type is used for liquid allowed dilute.

High hardness ceramic and ally are adopted for material of friction parts. It possesses high abrasive resistance & shake proof to guarantee that sealing effect can be satisfied by customer in various conditions.
