A4VSO125DR/30L-PPB13N00 Rexroth Axial Piston Pump
Product Overview
The A4VSO125DR/30L-PPB13N00 is an axial piston variable displacement pump from the Rexroth A4VSO Series 30, manufactured in Germany for open-circuit hydrostatic drives. It uses a swash plate design where output flow is proportional to drive speed and displacement, with stepless adjustment via swash plate angle. The DR control provides constant-pressure regulation: when system pressure reaches the setpoint, the swash plate angle reduces automatically to maintain pressure with minimal flow, cutting energy loss during hold cycles. Rated at 350 bar nominal / 400 bar peak, it is built for continuous duty in steel, mining, press, and marine hydraulic systems.

Frequently Asked Questions
Q: Is the A4VSO125DR/30L-PPB13N00 made in Germany?
A: Yes. This configuration is produced in Rexroth Germany facilities. We provide original label photos, test report, and certificate of origin on request.
Q: What does DR control do vs LR2G?
A: DR is constant-pressure control - displacement drops to near zero at set pressure. LR2G is hyperbolic constant-power control. DR is preferred for clamp/hold; LR2G for power-limited prime movers.
Q: Can I replace an old A4VSO125DR/30R- … with this L-rotation unit?
A: Only if your motor/drive train requires left-hand rotation. R and L shafts rotate opposite; mixing them will reverse pump direction. Confirm rotation before ordering.
Q: Does PPB13N00 fit standard SAE hoses?
A: Yes. Code 13 means SAE pressure (B) and suction (S) flanges on side, 90° offset, with metric mounting bolts. Adapters to NPT/ORFS are common but not built-in.
Q: Lead time?
A: Stock units 1-3 working days; non-stock 1-2 weeks depending on quantity.
