A4VSO180DFR/30L-PPB25N00 Rexroth A4VSO180 Industrial Piston Pump Made in Germany

The Rexroth A4VSO180DFR/30L-PPB25N00 is a genuine A4VSO series open-circuit swashplate axial piston variable pump, manufactured in Germany. With a displacement of 180 cm³/r and DFR pressure & flow compound control, it delivers reliable high-pressure performance up to 350 bar nominal / 400 bar peak. This model is widely used in hydraulic presses, steel mill systems, marine deck machinery, and heavy industrial power units requiring precise flow and pressure regulation.

• Swashplate design with infinitely variable displacement for energy-saving operation
• Excellent suction characteristics and low noise level
• DFR control enables pressure limiting and flow demand adjustment via pilot signal -- ideal for load-sensing systems
• Through-drive capability on tandem-ready variants of the A4VSO series
• Robust cast-iron housing designed for continuous heavy-duty industrial service
• Compatible with variable speed drive (VSD) applications

• Hydraulic presses - ceramic presses, forging presses, stamping lines
• Metallurgy - rolling mills, continuous casting machines, furnace hydraulics
• Marine & offshore - winches, cranes, deck machinery hydraulic power units
• Heavy machinery - tunnel boring machine (TBM) auxiliaries, mining hydraulics
• Industrial test rigs and large injection molding machines

A: No. The A4VSO series is designed exclusively for open circuit (open loop) systems. For closed circuits, use the A4VG or A4VM series.

A: DR is constant pressure control only. DFR is pressure + flow compound control, allowing remote pilot adjustment of both pressure setting and flow demand -- suitable for load-sensing and energy-efficient systems.

A: Fill the pump housing with clean hydraulic oil through the case drain port to purge air before first start. Ensure the case drain line discharges above the tank oil level and verify motor rotation matches the specified left-hand (L) direction.
