A7VO series inclined-axis axial piston pump—a reliable and high-performance solution widely used in engineering machinery, concrete pump trucks, and other industrial applications. Engineered for durability and precision, the A7VO pump meets the demands of high-pressure, high-efficiency hydraulic systems.
Key technical specifications:
Displacement Range: 55 mL/r to 160 mL/r, with common models including A7VO55, A7VO80, A7VO107, and A7VO160. For example, A7VO55 offers 55 mL/r, while A7VO160 reaches up to 160 mL/r.
Operating Pressure: Rated at 35 MPa (e.g., A7VO55, A7VO107), with peak pressure reaching 40 MPa (400 bar) on models like A7VO160.
Flow Characteristics: Maximum flow reaches 170 m³/h under low pressure and approximately 120 m³/h under high pressure (based on A7V series reference). Features constant power variable control for automatic flow adjustment in response to load changes.
Speed & Power: Rated speed ranges from 2300–2500 r/min (e.g., A7VO55 at 2300 r/min). Power output ranges from 75 kW (reference A6VM series) to higher-capacity configurations.
Control Method: Utilizes electro-hydraulic proportional technology to adjust displacement, enabling precise response to varying load conditions.
Typical Applications:
Concrete Pump Trucks: Models such as A7VO55 and A7VO80 are widely used in boom systems of Zoomlion, Sany, and similar brands, supporting 46–56 meter booms.
Construction Machinery: Ideal for high-pressure systems in excavators, cranes, and roadheaders.
Additional Features:
Housing material: Cast iron, ensuring high resistance to pressure impact.
Hydraulic medium: Compatible with 46 or 68 hydraulic oil, operating temperature range from -20 °C to 90 °C.
Installation: Supports side-mounted or horizontal installation, adaptable to diverse equipment layouts.
