Company Introduction

Shijiazhuang Aier Machinery Co., Ltd. is a large-scale professional manufacturer of slurry pumps, gravelpumps, dredge pumps, sewage pumps and clean water pumps in China.

All products are mainly supplied to environmental protection, wastewater treatment, urban water supplyand drainage, mine, metallurgy, coal, petrochemical, building material, thermal power FGD, riverdredging, tailing disposal and other fields. The products are selling well in China and sold far toGermany, U.S., Canada, Australia, Russia, Ukraine, Kazakhstan, Brasil, Chile, Argentina, Bolivia,Malaysia, Indonesia, India, Poland, South Africa, Tanzania, etc.

Our firm has strong technical force and is specially engaged in the research of abrasion resistantmaterials of slurry pumps, sewage pumps and water pumps and the development of new products. Thematerials include high chrome white iron, duplex stainless steel, stainless steel, ductile iron, rubber, etc.

We use CFD, CAD method for product design and process design based absorbing experience of worldleading pump companies. We integrate molding, smelting, casting, heat treatment, machining andchemical analysis, and have professional engineering and technical personnel.

Our company started to build our new factory in 2013 and finished in Spring of 2014. The new factory is

located in Lincheng Xingtai Hebei, covering 67,000 m 2 and of annual design annual casting capacity3,000 tons. In the new factory, we can produce different parts from small to huge. Casting & machiningorders are welcome as well.

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.

Transmission Module Design

Large diameter pump shaft, cylindricalConstruction of heavy load, metric

bearing using oil lubrication or greaselubrication; opened in serial, theconstruction features of small volumeand high reliability.

Shaft Bearing AssemblyA large diameter shaft with a short overhang minimizesdeflection and vibration.Heavy duty roller bearings are housed in a removable

bearing cartridge.

Pump BaseFasten the pump in the base with a minimum number of boltsand 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.
