Rexroth A4VSO Hydraulic Piston Pump with 10-140 cc/rev Displacement 1500-2700 rpm Rotation Speed and 30-90°C Applicable Temperature

A4VSO series pumps, including the A4VSO40 and A4VSO71, are widely used across various industrial sectors. They are commonly found in heavy machinery, industrial hydraulic power units, and other applications requiring robust and efficient variable flow hydraulic power in an open-circuit configuration.

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').
