Bosch Rexroth A10VG45 axial piston hydraulic pump

The A10VG45 is a swashplate-designed, axial piston variable pump engineered specifically for hydrostatic drives in closed circuits. Fluid flow is proportional to both the drive speed and the pump's displacement. By adjusting the swashplate angle, operators or automated systems can seamlessly vary fluid output from zero to its maximum capability.

Key Features and Integrated Components

What elevates the Bosch Rexroth A10VG45 from a standard piston pump to a comprehensive powertrain solution is its integration of auxiliary components within a singular housing.

1. Integrated Boost Pump (Charge Pump)

Closed-circuit systems require a continuous replenishment of fluid to compensate for internal leakage and to maintain control pressure. The A10VG45 features a built-in boost pump that:

Safeguards the main rotary group against cavitation by maintaining a positive suction pressure.

Supplies the required pilot oil pressure for control devices (like standard hydraulic or electronic displacement controls).

2. Built-in Relief and Boost Valves

Space and piping are at a premium in mobile machinery. The A10VG45 integrates high-pressure relief valves to protect the hydrostatic drive from catastrophic overpressurization. Additionally, integrated boost-pressure relief valves prevent the charge system from spiking, ensuring system longevity.

3. Through-Drive Capability

The pump can be optioned with a through-drive shaft, allowing engineers to mount auxiliary pumps (such as gear pumps or additional piston pumps) directly to the rear of the A10VG45. This enables a single prime mover to power multiple hydraulic circuits simultaneously.

Real-World Applications

The combination of compact packaging and high pressure limits makes the A10VG45 a staple across several heavy industries.

Mobile Construction Equipment

In compact wheel loaders, skid steers, and small telehandlers, the A10VG45 serves as the heart of the hydrostatic travel drive. Its ability to shift smoothly from forward to reverse provides operators with precise inching capabilities and smooth deceleration.

Agricultural Machinery

For modern harvesting equipment and self-propelled sprayers, the pump offers reliable ground-drive power. The EP (electric proportional) control option allows the machine's central computer to adjust vehicle speed dynamically based on engine load and field topography, maximizing fuel economy.

Municipal & Material Handling

Small sweepers, forklifts, and yard tractors utilize the A10VG45 for dependable, low-maintenance power delivery where traditional mechanical transmissions are too bulky or rigid.
