>>>Parameter Table of 4 inch electric high pressure water pump industrial

This series of pump is horizontal multistage single suction centrifugal water pump. This pump is efficient , reliable, and durable with low noise performance, easy maintenance and wide scope of usages. We specialize in manufacturing D, DF, DY and MD series of single-suction multistage centrifugal pumps, which are suitable for different liquids.

The pump is applicable to deliver those fluid without solid, particles or any other suspended stuff, water for instance.While oily and corrosive or solid contained fluid can be pumped by means of material modification, sealing methods, and cooling system adding.

D type : Used for  transmission of water free of solid particles and temperature below 80℃ , or similar physical and chemical liquid. Suitable for mining, mill and city water supply and drainage .

DF type : Used for transmission of corrosive liquid with temperature range for -20℃ ~105 ℃ and non-solid particles material ,sealing methods ,structure of the pump and motor model can be determined by medium, gravity ,density ,working temperature and the suction pressure .

DY type : Used for transmission of non- solid oily liquid and petroleum product with temperature range of  -20℃ ~105 ℃ and viscosity less than 120cST .

MD type : Used for transmission of neutral liquid from mining well or other similar liquid .The density and size of particles of the sewage shall be less than 1.5 % and 0.5 mm respectively . The temperature range of the sewage shall be -20℃ ~80 ℃ .

1) High Efficiency and Energy saving

We have developed our unique technology for manufacturing, model designing and making ,foundry techniques of  hydraulic parts to assure their brightness , cleanliness, and accurate dimensions . So the actual efficiency are at least 2% higher than other general multistage centrifugal pumps .

2)Advanced process equipment

Every single processed part will have cleaned by means of advanced imported cleaning equipment for better assembling concern . Besides material inspection ,hydraulic test , static balancing testing , all pump rotors beyond 6 grades will have axial movement tested controlled within 5 millisecond ,and then the balancing test shall be made according to G2.5 grade . Recheck axial movements of all shafts after assembly to assure the quality of the pump .

3)Unique structure

A sealing O-ring is set between balancing ring and fitting surface of the pump to avoid high pressure water coming into balancing stage and wear and tear of the balancing  plate to obtain better durability . Wear indicator of the balancing plate is set DN200. This makes the replacement of balancing plate reasonably to assure fine operation .

4)Material choosing

Balancing plate and the area around can be made of welding alloy , alloy steel or ductile cast iron QT600Mn2 concerning their high surficial hardness and fine durability . Flowing-over part of MD pump is of abrasion resistant by using  material of alloy wear resistant ductile cast iron or high-grade wear-resistant ductile cast iron .

5)Fine appearance

The appearance of the pump is fine taking advantage of precise mold casting procedures and automatic painting .
