   Multi-stage Centrifugal Pump 

Introduction                                                                           

This series of  pump is of sub-horizontal , multi-stage single-suction and centrifugal , using state-recommended hydromodule .  pump is efficient , reliable, and durable with low noise performa-nce , easy maintenance andwide scope of  usages . 

We specialize in manufacturing D ,DF,DY and MD series of single-suction multistage centrifugal

pumps based on our 20 years plus history and fame of biggest multistage pump manufacture. 

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.

Technical Feature                                                                                       

1. Energy saving

2. Advanced process equipment

3. Unique structure

4.Fine appearance

5.The shaft is fully sealed structure to ensure no contact with the media,do not rust,long service

lift.

6.Seal soft packing seal or mechanical seal,sealing,safe,reliable,simple structure,convenient

maintenance.

7.The pump runs smoothly,low noise.

8.Advanced hydraulic model,high efficiency,wide rage of performance.

Model meaning                                                                                           

Ex : D ( DF, DY, MD ) 600-60*6

D....multi-stage clean water centrifugal pump
DF....corrosion-resistant multi-stage centrifugal mining pump
DY---multi-stage centrifugal oil pump
MD....wear-resistant multi-stage centrifugal mining pump
600....the design point of capacity is 600 m3/h
60..... The design point of single-stage head is 60 m
6 ..... The pump stage is 6

Ex : 150 MD 30* 7
150..... The pump inlet diameter is 150 mm
MD .....wear-resistant multi-stage centrifugal mining pump
30.....the design point of single-stage head is 30 m
7.....the pump stage is 7

Note : D ( DF, DY , MD) 80-30 is the customary method , of
which 80 means the inlet diameter is 80 mm, 30 means single-
stage pump design point head is 30 m , others meaning is the
same method as above .

Performance Range                                                                                    

D,DF,DY,MD-Type pump has the same performance parameters and installation size

Inlet and outlet diameter of the pump:40-300mm

Capacity Q=3.75~1240m3/h

Head H=19~1200m

Note : The performance parameter are the normal temperature water testing values

Application                                                                                                 

Horizontal Multi-stage centrifugal pumps according to their scope of use can be divided into the following types :

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 120sST .

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 ℃ .
