HP3G SERIES
Swash-plate Type axial Piston Variable Displacement Pump
HP3G series variable axial piston pump with swashplate design for hydro-static drives in closed circuit, high pressure, high speed , high reliability, low noise, can be applied in engineering machinery and mobile machinery.
Features
·Variable axial piston pump of swashplate design for hydrostatic drives in closed circuit.
·The flow is proportional to the drive speed and displacement. The flow increases as the angle of the swashplate is adjusted from zero to its maximum value.
·Flow direction changes smoothly when the swashplate is moved through the neutral position.
·Two pressure-relief valves are provided on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overload.
·The integrated charge pump can provide system replenishing and cooling fluid flow.
·High reliability, long working lifetime
·Compact structure, high power density.
