A10V(S)O Axial Piston Pumps
A10V(S)O is swashplate type variable displacement axial piston pump, widely used for open-circuit hydraulic system. It converts mechanical energy into hydraulic energy, acting as the power core of your Machine. The pump delivers stable high-pressure oil flow and supports stepless flow regulation by adjusting swashplate angle, offering excellent versatility for mobile and industrial hydraulic applications.

Working Principle
When the drive shaft rotates, the cylinder block spins together with 9 pistons. Pistons slide against the swashplate via sliding shoes and perform reciprocating axial movement. Piston retraction = oil suction; piston compression = oil discharge. Changing swashplate inclination angle adjusts piston stroke, so displacement and output flow can be continuously modified to match load demand of the hydraulic system.
Key Features
1. Stepless variable flow, fast control response, high volumetric efficiency
2. Compact layout, favorable power-to-weight ratio
3. Drive shaft bears axial and radial loads, robust for heavy-duty working conditions
4. Multiple control modes: constant pressure, constant power, constant flow, proportional control
5. Universal through-drive design, easy multi-pump combination, simplifies system arrangement
6. Low noise, reliable sealing, optional version for water-containing hydraulic fluids
