Features
● Variable displacement axial piston pump of swashplate design for hydrostatic drives in open circuit hydraulic system
● Designed primarily for use in mobile applications
● The pump operates under self-priming conditions, with tank pressurization, or with an optional built-in charge pump (impeller)
● A comprehensive range of control options is available matching any application requirement
● Power control option is externally adjustable, even when the pump is running
● The through drive is suitable for adding gear pumps and axial piston pumps, i.e. 100% through drive
● The output flow is proportional to the drive speed and infinitely variable between maximum and zero
