Product Overview
▔▔The Rexroth Series Hydraulic Control Variable Axial Piston Pump is a premium, high-efficiency hydraulic drive component designed for both open and closed-circuit hydrostatic systems. Engineered using dynamic swashplate or bent-axis variable displacement principles, this series offers precise, energy-efficient fluid regulation tailored to demanding industrial machinery and heavy-duty mobile equipment.
Key Advantages
▔▔-
High Power Density & Compact Footprint: Delivers maximum hydraulic output within a lightweight, space-saving frame.
Energy-Saving Flow Regulation: Variable displacement continuously adjusts the output flow to match system demand, drastically reducing energy losses and thermal buildup.
Low Noise & Dynamic Response: Precise piston kinematics ensure ultra-smooth operation with reduced acoustic levels across high-pressure ranges.
Versatile Control Modules: Supports pressure control (DR/DRG), flow control (DFR/DFR1), load-sensing systems (LA/LR), and electro-hydraulic proportional control.
Exceptional Durability: Premium bearings and hardened internal components ensure extended service life under continuous heavy-duty operation.

FAQ
▔▔Q1: What is the primary difference between open-circuit and closed-circuit Rexroth axial piston pumps?
A: In an open-circuit pump (e.g., A10VSO, A4VSO), hydraulic fluid is drawn directly from a reservoir tank and returned back to the tank after passing through the system actuator. In a closed-circuit pump (e.g., A4VG), the returning fluid flows directly back into the pump's inlet port without returning to a main reservoir, making it ideal for compact, high-performance travel drives.
Q2: What does "Load-Sensing (DRF / LA Control)" mean in a variable pump?
A: Load-Sensing control automatically adjusts the pump's displacement and output flow to match the exact requirements of the load currently being driven. The pump maintains a set pressure differential above the actual load pressure, preventing wasted energy and overheating when full flow is not required.
