Widely used in construction machinery, mining equipment, agricultural machinery, and wind turbine yaw systems, the A7V pump delivers exceptional power density and precise pressure control under dynamic loads.
Key models in the series include A7V20, A7V28, A7V55, A7V80, A7V107, A7V160, A7V200, and A7V250, with displacements ranging from 20 to 250 ml/rev. These pumps operate at working pressures up to 32 MPa and support speed ranges of 1500–3000 rpm, depending on model and application. By adjusting the tilt angle (α) of the shaft relative to the rotor, the pump achieves smooth oil suction and discharge, with variable displacement control and constant power regulation for optimal efficiency.
When selecting the right configuration, we recommend considering system requirements carefully. For flow and head, a safety margin of 5%–10% above normal operating values is advised. Working pressure can reach up to 31 MPa, while maximum speed varies by model—for instance, the A7V160 operates at up to 2240 rpm under standard conditions.
To ensure long service life, proper maintenance is essential. We recommend regular hydraulic oil replacement, use of compatible and clean fluids, and avoidance of prolonged overload operation. In applications involving corrosive media, solid particles, or hazardous fluids, material compatibility and sealing solutions should be selected accordingly—such as wear-resistant designs or leak-free configurations where necessary.
For repair and servicing, accurate fault diagnosis is critical. Common issues such as pressure loss or oil leakage should be assessed before any intervention to ensure correct and efficient repairs.
