Principle of Operation


Pressure regulating valve – controls output pressure and prevents pump overload

1. Drive shaft – via electric motor, hydraulic motor, belt and pulley, etc.
2. Roller bearings – rigid support, immersed in lubricating oil bath
3. Fixed angle cam – translates rotary motion into linear to the hydraulic cells
4. Hydraulic cells – displace diaphragms via pressurized oil
5. Diaphragms – hydraulically balanced, no stress during flexing
6. Inlet valve assemblies – simple design, allows liquid into pump chamber
7. Outlet valve assemblies – allows liquid to flow into pressure discharge line
8. Pressure regulating valve – controls output pressure and prevents pump overload
