Engineering Features & Advantages

Precision Swashplate Performance: The axial piston swashplate design with DFR1 control delivers infinitely variable displacement, automatically adjusting flow output to match system demand while maintaining constant pressure — minimizing energy loss and heat generation.
Load-Sensing Efficiency: The integrated DFR1 pressure and flow compensator ensures the pump only delivers the flow required by the load, resulting in significant energy savings and reduced hydraulic fluid heating in continuous-duty applications.
High-Pressure Capability: Rated for continuous operation up to 280 bar and peak pressures of 350 bar, suitable for the most demanding industrial hydraulic circuits.
Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
