The A10VO and A10VSO pumps are engineered for precision and reliability, built around a robust internal structure comprising key components such as the plunger cylinder, swash plate, variable piston, and integrated control mechanisms. The swash plate design enables infinitely adjustable displacement by varying the tilt angle, allowing precise control over flow and pressure output. This adaptability is supported by a responsive variable mechanism—including reset piston, spring, and control valve group—ensuring optimal alignment with dynamic system demands.
In terms of operation, the A10VO pump starts at maximum displacement under spring force, then adjusts automatically when the flow control (FR) or pressure control (DR) valve activates, enabling efficient energy use in open circuits. In contrast, the A10VSO pump delivers proportional control of flow, speed, and displacement, making it ideal for applications requiring smooth, stable performance in medium-pressure industrial environments.
These performance characteristics make the A10VO particularly suitable for open-loop systems in construction machinery and hydraulic presses, while the A10VSO excels in industrial settings such as machine tools and lathes, where compact design, low noise, and high reliability are essential. Both models operate at a rated pressure of 280 bar, with peak pressures up to 350 bar, and support multiple control modes—including constant power, constant pressure, and constant flow—to meet diverse application needs.
