A4VSO250DR/30L-PPB13N00 Mining Piston Pump, Industrial Hydraulic Pump, German Rexroth
Product Introduction
The Rexroth A4VSO250DR/30L-PPB13N00 is a genuine German-made A4VSO series open-circuit axial piston variable pump with 250 cm³/r displacement and DR constant pressure control. Designed for continuous heavy-duty service, it is widely specified in mining hydraulic power units, mineral processing plants, crusher main drives, and underground support systems.
The DR control maintains a preset system pressure by reducing displacement toward zero at setpoint, minimizing energy loss and heat generation in constant-pressure circuits. Port configuration is PPB13 (SAE smaller port/flange vs PPB25) — commonly selected for compact manifold integration in mining skids.

Frequently Asked Questions
Q1: What is the difference between PPB13 and PPB25 on A4VSO250 pumps?
A: Both use SAE flanges and ports, but PPB13 has the smaller SAE port/flange size suited for compact manifold blocks, while PPB25 uses larger SAE ports for higher flow plumbing. Pump performance (displacement, pressure, flow) is identical — selection depends on your hydraulic manifold/standard.
Q2: Is DR control suitable for a mining crusher hydraulic power unit?
A: Yes. DR constant pressure control is common on crusher HPUs and clamping circuits where system pressure must be held steady with minimal flow when idle — the pump strokes near-zero, saving energy and reducing heat.
Q3: Can this pump be used in a closed hydrostatic transmission?
A: No. A4VSO is an open-circuit pump. Closed-circuit (track drive, wheel motor) applications require A4VG or A4VM series.
