Specifications：28/32 cc/rev
Rated pressure：345 bar
Peak pressure：380 bar
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.
