What is a multistage pump?

A multistage pump is a pump that contains different stages within the piping system where force is applied to the water. Each stage consists of one impeller as well as its accompanying diffusion components. The term “multistage” is usually used in reference to centrifugal pumps.

In many cases, these pumps are referred to in terms of how many stages they contain. For example, a pump with four stages might be referred to as a four-stage pump, or one with 10 stages would be referred to as a ten-stage pump.

D types of Multistage Centrifugal Water Pumps are single suction, horizontal segmental multistage pumps with level inlet entrance and vertical outlet. Usually they can connect with submersible pump and Mechanical Seal Electric Motor Multistage Centrifugal Boiler Feed Pump pump to increase the suction head lift. Compare to the other kind of pumps, they are cheaper and with high head, large capacity.

Industrial Electric Multistage Centrifugal Pump for Water Supply Performance Curve and Parameters:

Hunan Jiahua Pumps Co., Ltd is a professional manufacturer of horizontal multistage centrifugal pumps.We've been in this field over 20 years and set the factory from year 2010.We are a sound brand in China and develops a lot of distributors and end users.Also we offer repairing and maitenance of horizontal multistage pumps with reasonable price.From year of 2018 we decided to export horizontal multistage centrifugal pumps directly as we had exported a lot through export agent companies.Our main markets are Southeast Asian, Middle East, African, South America at present and we are trying to apply CE, UL certifications to develop more markets in the future.

As a professional manufacturer of horizontal multistage centrifugal pumps, we can produce different types of pump according to the application. We have D,DF,DY,MD,DG series of traditional horizontal multistage centrifugal pump; D(P), DF(P), DY(P), MD(P) DG(P)series of self balancing horizontal multistage centrifugal pump.

Usually D/D(P) types of multistage centrifugal pump 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/DF (P) types of multistage centrifugal pump are used for transmission of corrosive liquid with temperature range of -20℃ ~ 105℃ and non-solid particles. We will produce according to the gravity, density, working temperature and the suction pressure of the fluid.

DY/DY (P) types of multistage centrifugal pump used for transmission of non-solid oily liquid and petroleum product with temperature range of -20℃ ~ 105℃ and viscosity less than 120cst.

MD/MD (P) types of multistage centrifugal pump used for transmission of neutral liquid from mining well or other similar liquid. The density and size of the particles of the sewage shall be less than 1.5% and 0.5mm respectively. The temperature range of the sewage shall be -20℃ ~ 80℃.

DG/DG (P) types of multistage centrifugal pump used for low and medium pressure hot water transmission, also named as boiler feed pump. Temperature ranges from -20℃ ~ 150℃.

All the max suction pressure shall be 0.6Mpa.
