A7V Series Variable Piston Pump 20-1000 mL/r Displacement 350 Bar Pressure for Heavy Machinery
The A7V Series is a Rexroth inclined axis variable axial piston pump designed for heavy-duty, high-pressure hydraulic systems. This benchmark product delivers exceptional reliability, high power density, and robust starting capability for demanding applications in mining, metallurgy, shipbuilding, energy, and construction machinery.
Heavy-duty bearing design withstands extreme impact loads and high radial/axial forces. Robust housing and heat-treated components ensure long service life in harsh environments.
Inclined shaft design provides natural self-priming ability for reliable cold starts without auxiliary pumps.
- Constant Power Control (HD/EP): Prevents prime mover overload
- Pressure Control (DR/LA): Energy-saving pressure holding
- Electric Proportional (EL): Remote displacement control
- Load Sensing (LR): Matches flow to load requirements
Delivers displacement up to 1000 mL/r with 350 bar rated pressure and 400 bar peak pressure capability.
