Horizontal Anti-Corrosive Ring Section Type Multistage Centrifugal Pump

Horizontal Anti-Corrosive Ring Section Type Multistage  Centrifugal Pump

Short introduction:
D(DF) sequence is a centrifugal pump of horizontal,solitary suction,multistage and sectional construction.It owns the features of large performance,vast functionality assortment,easy procedure,low noise,effortless upkeep…D(DF) series was developed to pump thoroughly clean drinking water or fluids have near people of drinking water. Also,by modifying pump wetted components,it is able to pump fluids like very hot h2o,oil,corrosive fluids and fluids particles. 


  1. Flow rate:Q=20~540m3/h
  2. Total head:H=16~370m
  3. Pace:n=1450rpm/2950rpm
  4. S.g.:γ ≤1.fifteen
  5. Temperature:T=-~80ºC
  6. Pump diameter:80,100,a hundred twenty five,a hundred and fifty,two hundred,250mm


  1. YWINd hydraulic models with high efficiency and wide performance range.
  2. Smooth operation and low noise.
  3. Both packing seal and mechanical seal are available.
  4. Completely sealed shaft which is non-contact with fluid.
  5. The pump material can be changed to pump corrosive fluids. D(F) stands for a pump which is suitable for corrosive fluids,but its performance and is totally the same to D series.


  1. The pump set mainly consists of bearing housing,inlet and out section,middle section,guide vanes.
  2. The pump inlet is horizontal and outlet is verticalThe balance hose on the inlet is connected back to the water inlet side.
  3. Between bearings structure.The rotary part consists of shaft,impellers and a balance disk.
  4. The gaps between pump inlet section,middle section and outlet section are smeared by molybdenum disulfide compound calcium-based lubricating grease as the sealings. The gaps of rotary part and static part are sealed seal rings,guide vane sleeve and packing.
  5. YWIN shaft sealing is packing,can be customized as mechanical seal.
