The HA10VS0/31 series axial piston pump adopts a swash plate structure that enables stepless volume adjustment by changing the swash plate inclination angle. This innovative design allows for:
- Precise flow control by adjusting piston stroke in the cylinder
- Increased displacement when swash plate inclination increases
- Reduced displacement when swash plate angle decreases
- Flexible flow adjustment to match system requirements
- Improved overall system operating efficiency
Available in sizes from 18 to 140, with weights ranging from 12.9 kg (without thru-drive shaft) to 74.4 kg (with thru-drive shaft), depending on model configuration.
