End suction centrifugal pump is specialized in pumping water , liquid，chemical substances, etc. With compact structure , its working diameter ranges from 50mm to 300 mm, each model of our product has 4-5 impellers with different sizes, the rotation speed is 1450rpm, 1750rpm, 2900rpm, 3500rpm for optional. This circulation for air conditioner, sewage treatment and other fields.

DA is used for handing clear water or the liquids similar to the water physically and chemically finding the applications for water feed and supply service in mine, plants and towns, air -conditioning, extinguishing and irrigation.

In spite of the same specification, the pump’s performances vary with the diameter of the impeller. (Indicated with the block letters A, B and C in the type)

The pump is simple in structure, reliable in performances, small in size, low in power consumption, convenient in maintenance of good cavitation proof.

1.European Standard BS EN733/DIN24255 of performance and dimensions

2.Back-pull-out design, without having to disturb pump body and pipelines when servicing. 

3.All the models only use 3 kinds of pump shafts and bearing cover, make parts exchangeable. 

4.Impeller is optimized designed, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise. 

5.Casing and casing cover use wearing neck ring structure, which makes pump easy to maintain, makes parts work longer. The replaceable seal ring, makes pump work efficiently in a long time

1.Non-self-priming, single stage, single suction, horizontal, axial suction and radical discharge, pump body is fixed by base. 

2.Use bearing cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part. 

3.Compacted shaft, use deep grove grease lubricated roller bearing 

4.Connect pump and motor with semi-flexible coupling 

5.Use standard wearable mechanical seal. 

6.TEFC motor, size complies to IEC standard, installation type B3.
