Axial piston pumps utilize a series of pistons arranged in a circular design to deliver smooth, constant fluid flow. The A2FO series from Bosch Rexroth represents a versatile, heavy-duty option for fixed displacement axial piston pumps suited for mobile and industrial applications. In this blog, we’ll take a closer look at the A2FO pump range and how it can provide reliable hydraulic power in demanding conditions.
Introducing the A2FO Pump Series
The A2FO is an axial piston design consisting of nine pistons arranged in a circular array within the pump housing. As the pump shaft rotates, the pistons reciprocate to draw in and displace hydraulic fluid at a fixed rate. This generates a smooth, pulse-free flow that exits through the pump outlet port. The A2FO series is designed for pressures up to 5,075 PSI and flow rates from 1-155 GPM depending on specific model. The heavy-duty construction provides durable performance even in challenging environments.
Wide-Range Applications About Piston Fixed Pump A2fo
With their ability to generate high pressures and constant flow, A2FO pumps are well suited for:
- Mobile Hydraulic Systems – Used on excavators, derek, lifting equipment that require responsive, jerk-free motion.
- Industrial Machinery – Provides constant pressure and flow to power hydraulic presses, mesin cetak injeksi, test stands.
- Marine Applications – Delivers smooth hydraulic flow for propulsion and steering systems onboard ships.
- Aviation Applications – Compact and durable for use in hydraulic flight control systems.
- General Industrial – Reliable power for hydraulic motors, silinder, and actuators requiring steady flow.
Design and Construction – Axial Piston Fixed Pump A2fo
Some key design elements that contribute to durable axial piston fixed pump a2fo performance include:
- Pressure-Compensated Pistons – Minimizes piston tipping and wear for long service life.
- Pre-stressed Bearing Pins – Maintains precise piston alignment under load.
- Hardened Running Surfaces – Reduces friction and wear on pistons, shoes and cylinder.
- Rear Bearing Support – Adds additional load carrying capacity.
- Integral Valve Plate – Hardened steel with relief grooves for smooth operation.
- Cast Iron Housing – Rigid oil containment and minimized distortion.
- Multiple Mounting Options – SAE flange mounts for flexible installation.
By orienting the pistons vertically in the housing, the A2FO maintains a compact footprint for its displacement range compared to bent-axis designs. This allows more flexible installation options.
