A8V inclined axis axial piston variable displacement dual pump—a high-performance hydraulic solution with growing demand across the global construction machinery sector.
The A8V pump stands out due to its advanced engineering and adaptability in demanding applications. At its core, it features a slant axis plunger assembly, where the cylinder body is angled relative to the transmission spindle. This design enables efficient reciprocating motion of the plungers within the cylinder bores, facilitating reliable oil suction and pressurization through precise volume changes. The fixed, non-rotating oil distribution plate ensures smooth directional control of hydraulic fluid by managing connections between suction and pressure chambers via dedicated flow windows.
A key advantage lies in the integrated variable displacement control system. By adjusting the tilt angle of the swashplate or shaft, the pump delivers stepless displacement regulation, supporting sophisticated control strategies such as load sensing and power-sharing—critical for optimizing energy efficiency and machine responsiveness. Additionally, certain models incorporate auxiliary pumps and relief valves, enhancing system reliability through continuous oil replenishment and stable pressure management.
From a structural standpoint, the oblique shaft configuration eliminates the need for the drive shaft to pass through the cylinder body. This allows for a more compact cylinder design, contributing to higher rotational speeds and improved volumetric efficiency—consistently exceeding 95% under standard operating conditions. Precision machining ensures tight tolerances between plungers and cylinder bores, minimizing internal leakage and maximizing performance longevity.
Designed with modularity in mind, the A8V supports parallel dual-pump configurations and can be combined with axial piston or gear pumps, offering exceptional power density and flexibility. Its installation versatility further enhances integration potential, enabling direct mounting onto internal combustion engine flywheel housings while allowing shared suction ports—ideal for space-constrained or multi-function hydraulic systems.
These attributes make the A8V pump particularly well-suited for heavy-duty equipment, including rotary drilling rigs, dynamic compaction machines, and excavators. Capable of withstanding pressures up to 350 bar and delivering large flow rates, it serves as a cornerstone in static hydrostatic transmission systems where reliability, efficiency, and controllability are paramount.
