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 supply

and drainage, mine, metallurgy, coal, petrochemical, building material, thermal power FGD, river

dredging, tailing disposal and other fields. The products are selling well in China and sold far to

Germany, 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 resistant

materials of slurry pumps, sewage pumps and water pumps and the development of new products. The

materials 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 world

leading pump companies. We integrate molding, smelting, casting, heat treatment, machining and

chemical 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 m2 and of annual design annual casting capacity3,000 tons. In the new factory, we can produce different parts from small to huge. Casting & machining

orders are welcome as well.

Pump Introduction

WL Series pumps are cantilevered, horizontal centrifugal slurry pumps. They are suitable for delivering low density

slurries for metallurgical, mining, coal and building material departments. The shaft seal adopts both gland seal and

centrifugal seal.

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

Casing

Split casing halves of cast or ductile iron

contain the wear liners and provide high

operation pressure capabilities.

Impeller

The impeller is of 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.
