A4VSO250DR/30L-PPB25N00 Open Circuit Axial Piston Variable Pump, DR Constant Pressure Control, Made in Germany

The Rexroth A4VSO250DR/30L-PPB25N00 is a genuine A4VSO series swashplate axial piston variable pump for open circuit hydraulic systems, manufactured in Germany. It features a nominal displacement of 250 cm³/r with DR (constant pressure / relief) control, rated for 350 bar continuous and 400 bar peak pressure. The DR control maintains a preset pressure level by reducing displacement toward zero once system pressure is reached, making it a reliable and cost-effective solution for press circuits, industrial power units, and general heavy-duty hydraulic applications.

• Swashplate design with infinitely variable displacement for on-demand flow
• DR constant pressure control — pump strokes to zero when set pressure is reached
• Rated 350 bar continuous / 400 bar peak for heavy industrial service
• Excellent suction characteristics and low noise operation
• Robust cast-iron housing with long-life heavy-duty bearings
• Compatible with variable speed drive (VSD) systems
• Through-drive option available on tandem-ready A4VSO250 variants

• Hydraulic presses and stamping lines
• Industrial hydraulic power units (HPU)
• Metallurgy - rolling mill auxiliary hydraulics, furnace systems
• Test rigs and laboratory hydraulic benches
• General heavy industry requiring constant pressure supply
