Horizontal Single Stage Centrifugal Chemical Water Double Suction Pump

Horizontal Single Stage Centrifugal Chemical Water Double Suction Pump

Brief introduction:
ZSS sequence axial break up casing pump is a up-to-date product which absorbed the rewards of exact same kind pumps. It is a replacing merchandise of aged S sequence and SH series double suction pump. This up-to-date product owns the characteristics of greater hydraulic efficiency,high effectiveness,steady procedure,smaller sized in measurement.


  1. Flow rate:Q=fifty~6330m3/h
  2. Total head:H=nine~160m
  3. Speed:n=980rpm/2950rpm
  4. S.g.:γ ≤1.15 
  5. Temperature:T=-~105ºC
  6. Pump diameter:80~600mm


  1. Excellent energy-saving hydraulic models.
  2. Optimized hydraulic design,precisely casted impeller+casing+pump over and dynamic balanced impeller ensure the accurate performance of pump.
  3. Instead of traditional external circulation structure,a revolutionary design of sealing cooling and lubrication is adopted,which enables the complete internal circulation of cooling,lubrication and flushing.
  4. Internal sealing lubrication structure, the flushing to sealing system is more efficient.
  5. Straight line outline with stiffeners on pump cover,internal sealing lubrication structure,flexible structure design makes the pump more elegant.


  1. Single stage,double suction,axial split casing centrifugal pump.Double passage casing to reduce the axial forces.
  2. Both pump inlet and outlet are beneath the pump centerline,the rotary part can be removed from the casing without dismantle the pipelines.
  3. Shortened shaft and enlarged diameter of shaft design to increase the life of bearings and mechanical seals.
  4. Completely sealed shaft design,zero contact with fluids.
  5. Various materials of shaft sleeve to prevent the shaft from abrasion and corrosion.
  6. Both mechanical seal and packing seal are availablemechanical seal can be changed without dismantle the pump cover.
  7. Different rotation directions are available.

  1. It is suitable to pump clean water and fluids have close physical and chemical characters of water.
  2. widely used in sections of mining,city water supply,power plant water supply and drainage,farm irrigation and various water conservancy project.
