German Rexroth hydraulic pump designed for demanding industrial applications.
The Rexroth A4VSO180DR/30L-PPB13N00 is a swash plate type axial piston variable displacement pump designed for open circuit hydraulic systems. Flow is proportional to drive speed and displacement; stepless flow adjustment is achieved by varying the swash plate angle. The pump features high volumetric efficiency (≥95%), low noise operation, robust cast iron housing, and through-shaft capability for multi-pump combinations.
This unit is equipped with DR (Direct Pressure / Constant Pressure) Control — the pump automatically adjusts displacement to maintain a preset system pressure, with pressure adjustable via a remote relief valve.

A: DR stands for Direct Pressure Control (constant pressure control). In this mode, the pump automatically varies its displacement to maintain a preset system pressure. When system pressure drops below the setpoint, the pump increases flow; when pressure reaches the setpoint, the pump reduces displacement to near zero, only supplying leakage compensation flow. This significantly reduces energy consumption and heat generation compared to fixed displacement pumps. The pressure setting can be adjusted remotely using an external relief valve connected to the X-port.
A: Yes, the A4VSO series pump (size 180 and above) is compatible with HFC fluids under certain conditions. However, special seals (FKM/Viton) are recommended instead of standard NBR. Additionally, operating parameters such as speed, pressure, and fluid temperature must be derated — typically by 20-30% depending on the specific fluid. Please contact our technical team for a detailed application review before using with non-mineral oils.
A: The A4VSO180DR/30L-PPB13N00 follows ISO mounting and shaft standards (ISO 3019-2), making it mechanically interchangeable with many existing installations that use SAE 2-bolt flanges and parallel key shafts. It directly replaces older Rexroth A4VSO Series 10/20 pumps without modification. For cross-brand replacement (e.g., Eaton/Vickers, Parker Denison, Kawasaki), we recommend checking flange dimensions, shaft type, rotation direction, and port locations. Our sales engineers can provide compatibility verification upon request.
