A7VO series axial piston hydraulic pumps—high-performance solutions engineered for demanding applications across construction, chemical processing, marine systems, and heavy machinery.   With their inclined-axis plunger design, these pumps deliver exceptional efficiency, reliability, and precise control under high-pressure conditions.


The A7VO series supports constant power variable control, allowing real-time adjustment of displacement via pilot pressure.   This ensures optimal matching of flow and power output, enhancing both energy efficiency and system responsiveness.   Operating pressures typically reach 35–40 MPa, with select models such as the A7VO160 capable of withstanding up to 400 bar, making them ideal for high-intensity industrial environments.


Key application areas include concrete pump truck boom systems, roadheaders, mixers, and other engineering machinery, as well as critical hydraulic systems in chemical plants and maritime vessels.   The versatility and robustness of the A7VO series make it a preferred choice for clients seeking durable and scalable hydraulic solutions.


A7VO55 series: e.g., A7VO55LRH1/63R-NZB01, A7VO55LRD/63R-NZB01, A7VO55DR/63R-NZB01, A7VO55EP/63R-NZB01

A7VO80 series: e.g., A7VO80LRH1/63R-NZB01, A7VO80LRD/63R-NZB01, A7VO80DR/63R-NZB01, A7VO80EP/63R-NZB01

A7VO107 series: e.g., A7VO107LRH1/63R-NZB01, A7VO107LRD/63R-NZB01, A7VO107DR/63R-NZB01, A7VO107EP/63R-NZB01

A7VO160 series: e.g., A7VO160EP/63R-NPB01, A7VO160LRD/63R-NZB01

Model designations reflect displacement (55, 80, 107, 160) and functional features (e.g., EP, LRD, DR), enabling tailored selection based on specific operational requirements and configurations.
