Product Overview

▔▔

The Rexroth A11VO75 is a high-performance variable displacement axial piston pump built for open-circuit hydraulic systems. Engineered by Bosch Rexroth, a world leader in drive and control technologies, this pump is famous for its strong build, high efficiency, and excellent power delivery. It serves as the dependable heart for heavy-duty machinery, converting mechanical engine power into fluid energy with high precision.

Key Advantages

▔▔

Excellent Efficiency: The advanced swashplate design allows for precise fluid adjustment, minimizing power loss and reducing heat buildup.
Compact Footprint: Its high power-to-weight ratio makes it easy to install in tight machine compartments.
Low Operating Noise: Internal structural upgrades greatly reduce fluid pressure pulses and background noise.
Long Service Life: Equipped with heavy-duty bearings and tough internal parts to survive harsh working conditions.
Flexible Control Options: Supports load sensing, pressure control, and constant power control to match different job requirements.

FAQ

▔▔

Q1: What does "open-circuit system" mean for the A11VO75? A: In an open-circuit system, the pump draws hydraulic fluid from an unpressurized oil tank and delivers it to the control valves. After passing through the cylinders or motors, the fluid flows directly back into the tank rather than returning straight into the pump intake.

Q2: How often should I change the hydraulic fluid and filters for this pump? A: Maintenance intervals depend on your working environment. Generally, you should inspect fluid quality every 500 hours and completely replace the fluid and filters every 1,000 to 2,000 hours of operation to prevent wear from dust or metal particles.
