Rexroth Hydraulic Piston Pump A4VSO Variable High-Pressure Oil Pump with Cast Iron Construction and Variable Displacement

These pumps are compatible with different types of hydraulic fluids. The standard fluid is mineral oil, often indicated by the absence of a specific identifier. They can also use HF (high-performance) fluids, sometimes designated with an 'E'. For high-speed applications, specific fluid types (sometimes indicated by 'H') may be recommended. Always consult the official technical documentation for the most precise and application-specific fluid recommendations.

Yes, the A4VSO pump design can incorporate an auxiliary boost pump or a replenishing pump (a centrifugal pump). A standard pump might not include this feature, but a specific variant, such as version 25, can be supplied with a replenishing pump (denoted as 'L').

For comprehensive technical manuals, detailed performance curves, specific configuration options, and genuine spare parts, it is essential to contact authorized Rexroth distributors or service partners. They can provide precise information tailored to your specific model and application needs.
