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

WS/WSG gravel pumps are designed for continuously handling the most difficult higher abrasive slurries which

contain too big solids to be pumped by a common pump. They are suitable for delivering slurries in mining, explosive

sludge in metal smelting, dredging in dredger and course of rivers, and other fields. Type WS(G) pumps are of high-

head ones.

Typical Applications

Tailings, sugar beet, dredging, slag granulation, cyclone feed, slag granulation, suction hopper dredging,

barge loading, mill discharge, sand reclamation, booster pumping, sand waste, material transfer, etc.

Features

Construction of this pump is of single casing connected by means of clamp bans and wide wet-passage. The wet-

parts are made of Ni-hard and high chromium abrasion – resistance alloys. The discharged direction of pump can be

oriented in any direction of 360°.

This type of pump possesses the advantages of easy installing and operation, good performance of NPSH and

abrasion-resistance.

Typies of driver: V belt driver, gearbox driver, elastic coupling driver, fluid couplings driver, frequency conversion

driver, silicon controlled rectifier speed regulation etc.

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.
