hydraulic variable axial piston pump A4VG71 double tandem pump
Axial Variable Piston Rexroth Tandem Hydraulic Pump
hydraulic axial piston variable pump, low noise level, high efficiency, reliability; Axial and radial load capacity of drive shaft; favorable power/weight ratio, versatile controller range and short control response time.Variable pump in axial piston swash plate design for hydrostatic drives in an open circuit, the flow is proportional to the drive speed and the displacement. The flow can be steplessly varied by adjustment of the swash plate angle
Features
1. Designed primarily for use in mobile applications.
2. The pump operates under self-priming conditions, with tank pressurization, or with an optional built-in charge pump (impeller).
3. A comprehensive range of control options is available matching any application requirement.
4. Power control option is externally adjustable, even when the pump is running.
5. The through drive is suitable for adding gear pumps and axial piston pumps up to the same, i.e. 100% through drive.
