The Rexroth E-A10VSO28DFR1/31R-PPA12N00 is a high-performance axial piston variable displacement pump, characterized by high pressure, high efficiency, stepless variable displacement control, and excellent system integration capabilities. It is widely used in industrial hydraulic open-loop systems.
Key Selling Points:
Swashplate Variable Displacement Structure for Stepless Flow Regulation: By adjusting the swashplate angle, the displacement (28 ml/rev) can be continuously changed, allowing the output flow to precisely match load requirements, improving energy efficiency and control accuracy.
High Operating Pressure for Heavy-Duty Applications: Allows continuous operating pressure up to 28 MPa (280 bar), with a maximum of 35 MPa, suitable for high-power hydraulic systems in machine tools, metallurgy, and construction machinery.
Open-Loop Design for Strong System Compatibility: Specifically developed for open hydraulic loops, the flow rate is proportional to the drive speed and displacement, providing rapid response and adaptability to the power requirements of various industrial equipment.
Multiple control modes for flexible system adaptation: The DFR1 control mechanism supports pressure/flow composite control, automatically adjusting output according to system load to avoid energy waste and improve overall efficiency.
Standardized installation interface for easy replacement and integration: Compliant with ISO flange installation standards and SAE metric flange specifications, facilitating on-site installation and maintenance. Supports multi-pump tandem (through-shaft structure) multi-loop systems.
Low noise and high suction performance: Optimized housing design with two drain ports effectively improves suction conditions, reduces operating noise, and ensures stable operation even under high loads.
German-made quality for high reliability: Manufactured by Bosch Rexroth, employing precision mating and grinding technology, with a radial clearance of only 0.002–0.003 mm, ensuring long service life and high stability.
This pump is widely used in hydraulic presses, broaching machines, mining machinery, ships, and other equipment requiring high stability and efficiency, serving as a core power component in modern industrial hydraulic systems.
