A Smarter, Cost-Efficient Option for Medium-Pressure, Closed-Loop Applications
For machine builders operating in the medium-pressure range, finding the right balance between performance, control, and cost has often meant compromise. The Bosch Rexroth A1VC Series 20 changes that.
Positioned between higher-cost, high-pressure platforms and legacy solutions, the A1VC axial piston pump introduces a new category of closed-loop performance that delivers the control capabilities and durability needed for modern mobile equipment, without the complexity or cost of overbuilt systems.
- Compact, high-performance axial piston variable pump
- Designed for medium-duty closed-loop applications
- Delivers reliable power, flexible control, and reduced engineering complexity
- Robust swashplate design
- Durable, modular, high power density
- Compact footprint for ground drive applications
- Cost-competitive when partnering with Evolution
