FAQ:

 What is the A10VSO series piston pump?

The A10VSO is a swash-plate axial piston variable pump designed for open-circuit hydraulic systems. It is widely used in industrial and mobile applications due to its high efficiency, low noise, and long service life. Key features include:

• Flow rate adjustment via swash plate angle control.

• ISO/SAE standard mounting flanges and SAE metric flange connections.

• Continuous operating pressure up to 280 bar (peak: 350 bar).

• Multiple control options (pressure, flow, power, etc.).

• Through-drive capability for multi-pump systems.

2. What are the available displacement sizes?

The A10VSO series offers displacements from 10 to 140 cc/rev, categorized into:

• 31/32 series: 18–140 cc/rev (common sizes: 28, 45, 71, 100, 140).

• 52 series: 10 cc/rev (limited models).

• Reason:
Excessive resistance in the oil suction pipeline (such as clogged oil filter, low oil tank level, or air leakage in the inlet pipe).
Internal leakage of the pump (scratches on the oil distribution plate, poor sealing, sand holes, etc.).
The inclination angle of the inclined plate is too small and the displacement is insufficient.
Motor reversal (requires adjustment of phase sequence).
• Solution:
Clean the oil filter, add oil to the normal liquid level, and check the sealing of the pipeline.
Replace worn parts (such as plungers, oil distribution plates) or grind mating surfaces.
Adjust the variable piston to increase the inclination angle of the inclined plate.
