2. Descriptions

Inside the pump, there're nine pistons which are parallel to the driven shaft. The nine pistons reciprocate inside the rotating cylinder along the slopping cam plate, then the fluid are conveyed by the volume change incurred by that reciprocating motions. 

  • It's designed for conveying high pressure, low viscosity and corrosion fluid meda, such as seawater, and other type of water with high salinity (TDS) and high pressure
  • The components of pump are made of anti-corrosion materials: Duplex, super duplex, and carbon fiber reinforced Polyetheretherketone (PEEK)
  • Flow range from 0.3 m3/h to 44.7 m3/h
  • Extra long service life span and low maintenance design
  • The pump is with fixed discharge capacity, the flow flux has direct proportion to the input shaft RPM and the discharge capacity of the pump, no reverse pressure is related.

 3. Key features

  • Simple operation
  • Extreme low maintenance cost
  • Self lubrication axial piston pump
  • Minimal operation cost

4. Applications

  • Seawater RO plant, seawater desalination equipment, seawater reverse osmosis system
  • Oil drilling rig
  • Landfilled leachate treatment
  • Fire extinguisher (extinguishing) system spray
  • Sepcial separation RO membrane system
  • Other membrane system for highly TDS water treatment

5. Parts | accessories

  • Check valve with grooved coupling
  • High pressure flexible pipes | piping
  • Tee and cross Tee pipe quick joints and fittings

​6. Competitive advantage

The self lubricating axial piston pump features its smaller size, but macro energy efficiency. Highest outlet pressure is up to 80 bars (8Mpa), All components are made of corrosion resistance materials: Duplex, Super Duplex, carbon fiber reinforced PEEK. The WE series high pressure pump are widely used in high TDS seawater RO desalination, landfill leachate treatment, waste water treatment, etc.
