Excavator EC55 Main Pump EC55B Hydraulic Pump AP2D28 AP2D25 AP2D28 AP2D36 AP2D18 AP2D36LV Hydraulic Pump

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
