Adopts our proprietary pure water‑lubricated axial piston pump – oil‑free, self‑lubricating, self‑cooling, compact structure, high mechanical efficiency. Utilizes advanced materials, processing techniques and component structures – corrosion‑resistant, wear‑resistant, long life, maintenance‑free, world‑leading level. Coupled high‑pressure plunger pump technology increases single pump flow, making the system more compact and further reducing footprint. The pump outlet is equipped with a flushing check valve, allowing flushing without starting the high‑pressure pump, saving energy. Supports our own rotor energy recovery and coaxial booster device, lowering water production cost and providing superior, stable and reliable system performance.

The reverse osmosis seawater desalination system using our water‑lubricated axial piston pump offers the following advantages over similar products:
No need for oil lubrication – self‑lubricating, maintenance‑free, low cost, intrinsically safe and reliable; improves membrane cleanliness and product water quality. Small pump size, high efficiency, low energy consumption – the whole system is compact and aesthetically pleasing. Advanced materials and processes provide corrosion resistance, wear resistance, longer life, lower noise and vibration. Advanced sealing materials and structures ensure high volumetric efficiency and no leakage.
Adjustable swashplate structure allows flow adjustment without changing the overall pump configuration, meeting different system requirements at various stages – more energy‑efficient and economical without pump replacement. Integrated flushing check valve enables flushing without starting the high‑pressure pump, further reducing system energy consumption. Breaks the monopoly, replaces and exceeds imported products, lowers the total cost of existing seawater desalination systems, and ensures strategic security for national key projects. Local enterprise – convenient service and guaranteed delivery time.
Can be paired with our own rotor energy recovery and coaxial booster device or energy recovery pump set to further reduce water production cost.
