Product Overview

Axial Piston Variable Pump A4VG

– 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. – 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 ports 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 boost pressure-relief valve. – The integral pressure cut-off is standard – High pressure level for high power density and good efficiency
