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.

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.
