A10VNO series axial piston variable displacement pump, a high-performance solution designed for open-loop hydraulic systems. As a swash plate-type pump, it operates on the principle of stepless displacement control by adjusting the swash plate angle in response to system demands, ensuring precise and efficient flow regulation.
The pump’s robust design includes a plunger cylinder, swash plate, variable piston, and integrated control valve assembly. In its default state, a spring mechanism sets the swash plate to maximum displacement. When system pressure or flow requirements change, control valves—such as FR or DR types—actuate the variable piston to adjust the swash plate angle accordingly. For example, as outlet pressure reaches the preset threshold, the FR spool shifts left, driving the swash plate toward zero angle and minimizing displacement. Conversely, an increased throttle opening shifts the spool right, enlarging the swash plate angle and increasing output flow.
Rated at 280 bar with a peak pressure capacity of 350 bar, the A10VNO series delivers reliable performance under demanding conditions. Its energy-saving features stem from advanced constant pressure and constant flow controls, while its low-noise operation, high power-to-weight ratio, and coaxial drive configuration make it ideal for construction machinery, industrial hydraulics, and other heavy-duty applications.
Common models include A10VNO28, A10VNO45, A10VNO63, and A10VNO85, offering flexibility across various power and flow requirements. Please note that while some references indicate a nominal pressure of 210 bar and maximum of 250 bar, the standard specifications support higher ratings, ensuring superior durability and efficiency.
