FAQ:

1. What is the A10VSO28 pump?

The A10VSO28 is a variable displacement axial piston pump from Bosch Rexroth’s A10VSO series. It is designed for open-circuit hydraulic systems and offers precise flow control with pressure-dependent displacement adjustment.

2. What are the key features of the A10VSO28?

• Variable displacement – Adjusts flow based on system demand.

• Pressure compensation – Automatically regulates flow to maintain set pressure.

• High efficiency – Optimized for energy savings.

• Compact design – Suitable for mobile and industrial applications.

• Multiple control options – Includes pressure, flow, and power control variants.

3. What is the maximum pressure rating?

• Continuous pressure: Up to 280 bar (4060 psi)

• Peak pressure: 350 bar (5075 psi)

4. What is the displacement volume?

The nominal displacement is 28 cm³/rev (1.71 in³/rev).

5. What type of hydraulic oil should be used?

Recommended fluids:

• Mineral-based hydraulic oils (ISO VG 15–68)

• Synthetic or biodegradable fluids (check compatibility)

• Maintain cleanliness (ISO 4406 18/16/13 or better)

6. What are common applications for the A10VSO28?

• Construction machinery (excavators, loaders)

• Industrial presses & injection molding

• Material handling equipment

• Agricultural machinery

7. How do I adjust the pressure setting?

The pressure compensator can be adjusted via the control screw (refer to the manual for calibration). Always adjust under controlled conditions.

8. What maintenance is required?

• Regularly check oil cleanliness and levels.

• Inspect seals and replace if leaking.

• Monitor for unusual noise or vibration.

• Follow Bosch Rexroth’s service intervals.

9. What are common troubleshooting issues?

Issue Possible Cause Solution
Low flow Worn pistons/valve plate Inspect & replace parts
Overheating High viscosity oil, clogged cooler Check oil grade, clean cooler
Noise Cavitation, air ingress Check suction line, bleed air

10. Where can I find technical documentation?

Download manuals, datasheets, and CAD files from the official Bosch Rexroth website or authorized distributors.
