Product Description

A4VSO DH1 Series Hydraulic Axial Piston Pump Product Description

This A4VSO DH1 series hydraulic axial piston pump is a high-performance solution tailored for industrial and heavy-duty machinery, covering multiple displacement models including A4VSO71, A4VSO125, A4VSO180, and A4VSO250. The A4VSO125 variant, in particular, features the HD1 control mechanism and 22R-PZB13N00 configuration (with part reference R910938362), delivering precise flow and pressure regulation to meet dynamic operational demands of hydraulic systems.

Built with a robust, wear-resistant structure, the pump maintains stable output even under extreme working conditions—such as high-pressure cycles, continuous load operations, and harsh environments with dust, vibration, or temperature fluctuations. Its durable design reduces maintenance frequency and extends service life, making it an ideal choice for construction equipment (excavators, loaders), mining machinery, cranes, and industrial hydraulic presses.

The pump’s compact footprint enables flexible installation in limited spaces, while its variable displacement technology minimizes energy loss and optimizes overall system efficiency. As a reliable replacement or upgrade component, it ensures consistent, high-quality fluid power transmission for hydraulic power units, supporting smooth and efficient operation of heavy machinery.
