Close circuit hydraulic pump HP4VC 28/45/53
Axial piston variable pump in swashplate design for hydrostatic drives in closed circuits
- Size：28/45/53 mL/r
- Rated pressure：300bar
- Max. pressure：350bar
- The flow is proportional to the drive speed and displacement and is infinitely varied
- The output flow increases from zero to the maximum value as the swashplate swivels
- The flow direction changes when the swashplate is moved through the neutral position
- Various mutually compatible control options to provide diverse control and regulation functions
- Two pressure relief valves on each high-pressure side to prevent overload of hydrostatic drives (pump and motor)
- Pressure relief valve with boost function
- Integrated boost pump works as the boost and control pump
- Maximum boost pressure limited by integrated boostpressure relief valve
- With integrated power cut-off valve as standard
