In early 2013 KSB will launch its new compact unit for reverse osmosis seawater desalination. The Salino Pressure Center consists of an axial piston pump and an axial piston motor, arranged on a common shaft. Driven by the diaphragm return flow, the axial piston motor transfers its power directly to the pump shaft. Three functions are fulfilled by one and the same unit:
- creating high pressure,
- compensating pressure losses
- recovering energy.
There is no need for a separate booster pump. The entire system runs on a single electric motor and frequency inverter. Compared to conventional energy recovery systems with pressure exchangers or Pelton turbines, this design saves up to 50 % in energy costs.
