A8V axial piston variable displacement dual pump—a high-performance hydraulic solution engineered specifically for advanced construction machinery, including excavators. With its innovative inclined-axis design and dual-pump integration, the A8V offers exceptional efficiency, reliability, and control flexibility in demanding applications.
At the heart of the A8V’s operation is its oblique shaft structure, where a precise inclination angle exists between the main shaft and the plunger group (cylinder body). As the main shaft rotates, the cylinder body is driven via a connecting rod, inducing reciprocating motion of the plungers within their bores. This action creates cyclic changes in sealed volume, enabling efficient oil suction and pressurization—critical for stable performance under high-pressure conditions.
A key advantage lies in the pump’s variable displacement capability. By adjusting the swashplate angle (or inclined shaft angle), the pump can infinitely vary its output flow to match system demands. It supports multiple control modes—including constant power, constant pressure, and electronic proportional control—offering superior adaptability across diverse working conditions.
The A8V features a “one housing, two movement sets, one variable mechanism” dual-pump configuration, maximizing compactness and operational synergy. In this setup, full power control ensures optimal engine load management: both pumps share a common power regulator, with half the sum of their outlet pressures fed back through a pressure balancer. This enables coordinated variable displacement while maintaining constant total power absorption—an ideal solution for energy-sensitive machinery.
Additionally, the system supports synchronous control through hydraulic or mechanical linkages that equalize the swashplate angles of both pumps. This ensures identical flow outputs, which is essential for synchronized functions such as travel drive and swing operations in excavators, enhancing machine stability and responsiveness.
Designed for heavy-duty use, the A8V pump delivers a rated pressure of up to 35 MPa. Its modular architecture allows flexible integration into complex hydraulic systems, making it particularly suitable for applications requiring high flow rates, robust pressure performance, and sophisticated control logic. These attributes make the A8V an excellent choice for modern construction equipment manufacturers aiming to improve productivity, fuel efficiency, and system reliability.
