A20VO Rexroth Piston Pumps
A20VO Rexroth Piston Pumps
Feature
The Rexroth A20VO piston pump is a two axial piston rotating group design and is designed for open circuit hydrostatic drive. It has a wide range of applications and is suitable for both mobile and stationary use. The pump contains proven components derived from the A11VO (RC 92500), A10VO/53 (RC 92703) or A4VSO (RC 92050) variable displacement pumps.
Variable displacement pump operates in self-priming condition with pressurized tank or supplementary pump (available for sizes 190...260). It offers a range of control options, including the ability to set constant power control (power control only) even when the device is running, allowing external adjustments.
The A20VO pump can be configured with a variety of controls, providing flexibility for different operating requirements. Additionally, it facilitates the installation of a gear pump or a second axial piston pump via a shared shaft drive unit. Output flow varies seamlessly in proportion to drive speed, providing continuous stepless regulation between maximum and zero displacement.
