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.
