Rexroth A4VG Series 40 Axial Piston Variable Pump

HBOETH BOLE HYDRAULIC A4VG280 REXROTH hydraulic piston pump

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 can be infinitely varied by adjusting the swashplate angle.    
Flow direction changes smoothly when the swashplate move through the neutral position.    
A wide range of highly adaptable control devices with different control and regulating functions, for all important applications.    
Two pressure-relief valves are provided on the high-pressure side to protect the hydrostatic 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
