Dimensions of the hydraulic pump (without control unit)
Features:
Variable axial piston pump of swashplate design
for hydraulic drives in closed circuit
The flow is proportional to the drive speed and displacement.
The flow can be infinitely varied by adjusting the swashplate
angle.
Flow direction changes smoothly when the swashplate is moved
through the neutral position.
A wide range of highly adaptable control devices with different
control and regulating functions,
For all important appliions.
Two pressure-relief valves are provided on the high-pressure side
to protect the hydraulic transmission (pump and motor) from
overload.
The high-pressure relief valves also function as boost valves.
The integrated boost pump acts as a feed pump and control pressure
supply.
The maximum boost pressure is limited by a built-in low-pressure
relief valve.
High pressure level for high power density and good efficiency
