Description of multistage centrifugal water pump 

There are two type of multistage centrifugal Water Pump we supply, it is horizontal multistage centrifugal water pump and vertical centrifugal water pump, they are both centrifugal theory, meet require of high pressure feedng water, high efficiency low noise make it to be the great choice in supping water system. Moreover high pressure performance make it works well in fire system, mining dewatering, agricultural irrigation, boiler feeding water. 

 

structure specification of centrifugal water pump 

The basic structure of multistage pump is composed of six parts, respectively, the impeller, pump, shaft, bearings, seal rings, stuffing box.

Impeller: 

it is a core part of multistage pump, smooth inner and outer surface help to reduce the flow friction loss, and play crucial roles in 

pumping water at very high pressure.

Casing: 

it is a body of multistage water pump, tplay a role of supporting & fastening, and connected to the bracket whitch mounting the bearing.

Pump Shaft: 

It is the main components of the mechanical energy transfer.

Shaft Bearing: 

it is a component to support the shaft, there are two kinds of rolling bearing and Sliding bearings. Rolling bearing use butter as a lubricant oil, Sliding bearings using a transparent oil as a lubricant. 

Sealing ring: 

use to increase the resistance of back-flow, and reduce internal leakageAlso known as leakage reduction ring, by this way, it is helpful for Increase the service life of the impeller and casing.

Stuffing Box: 

Composed of packing, seal loop, packing tube, packing gland, seal tube. Keep pump in vacuum state when working.

About us 

Shijiazhuang An Pump Machinery Company is a leading manufacturer of water pump in North of China, in China “North of China” means 

gathering place of heavy industry equipment. And we play an important role in suppling water pump and other heavy industry pump for 

customers from home and abroad sincerely. In a simple word, multistage water pump is one kind of centrifugal, as it has multiple impellers, so it is also called multistage pump, which has high pressue in pumping out water, so it is easy to pumping water at very high level.
