A4VSO250DR Rexroth Axial Piston Pump 250cc 350 bar DR

Model Number	A A4VSO 250 DR /30R-FPB13N00

Product Description

Product Overview

The A4VSO250DR/30R-FPB13N00 is the 250 cc-class core model within the Bosch Rexroth A4VSO series of open-circuit axial piston variable displacement pumps. The A4VSO series features a swashplate design where pump flow is proportional to input drive speed and displacement, with displacement steplessly adjustable from zero to maximum. Designed for open-circuit hydrostatic drives, the series operates at a nominal pressure of 350 bar with peak pressure of 400 bar.

Key Technical Advantages

1. DR Pressure Control with Constant Pressure Output
The A4VSO250DR/30R-FPB13N00 is equipped with a DR pressure controller. When system pressure reaches the setpoint, the pressure controller automatically reduces pump displacement, maintaining only leakage compensation flow to keep system pressure constant. The pressure setting range is 20–350 bar, precisely settable via the adjustment screw. The DR control offers short response times, rapidly stabilizing system pressure under load transients — ideal for hydraulic presses, test benches, and other industrial hydraulic systems requiring constant pressure output. The pressure controller is not a safeguard against pressure overload; a pressure relief valve must be installed in the hydraulic system.

2. Swashplate Design with High Volumetric Efficiency
The A4VSO series employs a swashplate axial piston rotary group design where swashplate inclination angle determines piston stroke and displacement. Pistons and cylinder bores are precision match-ground to micron-level clearances. Valve plate pre-compression and pre-decompression angles are CFD-optimized to minimize pressure spikes and flow pulsation. Volumetric efficiency remains above 95% at 350 bar continuous pressure. The swashplate configuration offers compact axial dimensions suitable for space-constrained industrial installations.

3. High-Strength Cast-Iron Housing with Long Service Life
The housing is precision-cast from high-strength cast iron, with the material’s damping characteristics effectively suppressing structural vibration and fluid-borne noise. The A4VSO series is renowned for exceptionally long service life, with bearings selected through system-level load analysis for long-term operation at 350 bar continuous pressure. The drive shaft is capable of absorbing axial and radial loads, enhancing system design flexibility.

4. Through Drive and System Expansion Capability
The A4VSO series supports through drive, allowing direct mounting of subsequent pumps of same or smaller size on the rear of the main pump for single-motor multi-pump compound hydraulic systems. This modular design provides flexibility for system expansion and customization without significant modifications to existing mounting foundations. The through-drive shaft specification and torque capacity must be matched to the power requirements of the subsequent pump.

5. Short Control Response Time and Excellent Suction Characteristics
The A4VSO control mechanism features short response times, with control spool and servo piston area ratios and spring rates precisely matched to ensure fast and stable displacement adjustment. Optimized suction flow passages provide excellent self-priming characteristics, reducing cavitation risk and aeration damage.

Expert Maintenance Tips

1. Hydraulic Fluid Cleanliness
The A4VSO series DR pressure control spool operates with extremely tight clearances and is highly sensitive to particulate contamination. System fluid cleanliness must meet ISO 4406 18/15/12 or better. Install a 10 μm absolute-rated filter element at the pump inlet. Replace elements at 500 hours after first commissioning, then every 1,000 operating hours or 6 months, whichever comes first.

2. DR Pressure Controller Setting and Adjustment
Set the DR pressure controller 15–20 bar above the maximum working load pressure, never exceeding the 350 bar nominal pressure. Adjust only with the system at zero load. Rotate the adjustment screw slowly and verify stable pressure gauge readings before proceeding. Notice: The pressure controller is not a safeguard against pressure overload. A pressure relief valve must be installed in the hydraulic system. Never adjust the controller while the system is under pressure.

3. Case Drain Line Requirements
The case drain line must return directly to the reservoir. Maximum permissible back pressure is 2 bar (0.2 MPa). The drain outlet must terminate below oil level at all times to prevent air ingestion. The drain line diameter must not be smaller than the pump case drain port size. For 250 cc class large displacement pumps, case drain flow is substantial — drain line design must fully account for flow demand to avoid excessive case pressure from pipe resistance.

4. Pre-Start Priming and Air Bleeding
Before first start, fill the pump housing with clean hydraulic fluid through the case drain port. After installation, turn the drive shaft by hand several revolutions to confirm free rotation without binding. Start at low speed with zero load and run for 5–10 minutes. Verify continuous bubble-free flow from the case drain. Only then apply load.

5. Through Drive End Maintenance
If equipped with through drive, regularly inspect rear pump mounting bolt tightness and spline connection wear. The through-drive end bearing is lubricated by the pump’s internal case drain circuit — no additional maintenance required. However, the rear pump’s power demand must not exceed the through-drive rated torque capacity. Inspect through-drive end bolt torque at 500 hours after first commissioning, then recheck every 2,000 operating hours.
