Electric Hydraulic Pump
Technical Specifications of A8VO80L
The Rexroth A8VO80L hydraulic pump is an axial piston variable double pump featuring a stable swash plate structure, engineered specifically for medium and small construction machinery. It boasts a single pump displacement of 80 mL/r, with a combined total displacement of 160 mL/r for the dual-pump design, ensuring sufficient flow and power for standard construction actions. The pump holds a rated pressure of 350 bar (35 MPa) and a peak pressure of 400 bar (40 MPa), capable of withstanding heavy load impacts without performance loss. At a rotational speed of 2240 r/min, it reaches a maximum flow rate of 2×179 L/min, with a driving power of 2×95 kW that perfectly matches 200-250 horsepower engines. Adopting an efficient power distribution control mode, it optimizes hydraulic system response and energy utilization, while the standard SAE J617 flange installation interface ensures universal fitment and easy installation. This model is primarily designed for 10-20 ton excavators and supporting loaders, making it a versatile and high-performance hydraulic component for the construction machinery industry.
This is a premium, fully assembled Rexroth A8VO80L hydraulic pump, equipped with a complete set of high-precision hydraulic parts to meet the maintenance and replacement needs of various mainstream construction machinery. The full assembly includes core components such as a durable pump body, high-strength pistons, precision-machined swash plate, wear-resistant valve plate, high-rigidity cylinder block, and heavy-duty drive shaft, all manufactured with strict adherence to original Rexroth technical standards to ensure stable performance and long service life. This hydraulic pump assembly serves as a reliable OEM replacement part, widely compatible with a full range of construction equipment, including John Deere 160C LC, Case CX130B, Sany SY135C-10, Zoomlion ZR220C, Sunward SWDM22, Komatsu PC130-8, Caterpillar 320D2, Hitachi EX160-6 excavators, as well as XCMG LW500KV and Liugong CLG856H loaders. It is specially designed to adapt to heavy-duty working conditions, delivering consistent hydraulic power output and efficient system operation for daily construction work, equipment overhaul, and performance upgrades.

8 Key Advantages & Product Highlights
1. Authentic Rexroth Structural Design & Standardized Parameters
Built strictly in accordance with the original Rexroth A8VO80L design drawings and technical parameters, retaining the classic axial piston variable double pump and swash plate structure. This ensures full interchangeability with original factory pumps, no parameter deviation, and seamless matching with the original hydraulic system of construction machinery, avoiding compatibility issues and ensuring stable, consistent operation after installation.
2. Complete Core Hydraulic Parts Included
This is a fully assembled pump unit, not a single separate part, and comes complete with all critical internal components: pump body, piston, swash plate, valve plate, cylinder block, and drive shaft. Customers do not need to purchase additional matching parts separately, providing a one-stop replacement solution that saves time on parts selection and reduces installation complexity for maintenance teams.
3. Exceptional Pressure Resistance for Heavy-Duty Work
With a rated working pressure of 350 bar (35 MPa) and a peak pressure resistance of 400 bar (40 MPa), this hydraulic pump can stably maintain pressure output under long-term heavy-load working conditions, such as continuous excavation, material lifting, and ground leveling. It resists pressure fluctuations and component damage, adapting to harsh construction environments like mines, construction sites, and roadworks.
4. High Displacement & Efficient Flow Output
Featuring a single pump displacement of 80 mL/r and a total dual-pump displacement of 160 mL/r, paired with a maximum flow rate of 2×179 L/min at 2240 r/min, it delivers strong and stable power to the excavator’s working device. This improves the speed and efficiency of excavation, rotation, and lifting actions, boosting overall construction productivity without compromising power performance.
5. Wide Engine Power Compatibility
Designed to support a driving power of 2×95 kW, this pump is perfectly matched with 200-250 horsepower engines commonly used in 10-20 ton construction machinery. It is compatible with different engine configurations across mainstream brands, eliminating the need for system modification or parameter adjustment, making it suitable for a wide range of equipment models and reducing application limitations.
6. Advanced Power Distribution Control System
Equipped with a professional power distribution control mode, this pump optimizes the distribution of hydraulic power according to actual working conditions, reducing unnecessary energy loss and lowering overall equipment fuel consumption. The system response speed is fast, with sensitive action control and no lag, enhancing the flexibility and operability of the equipment during use.
7. Standard SAE J617 Flange for Easy Installation
Adopts the international universal SAE J617 flange installation interface, with mounting dimensions fully consistent with original factory standards. It supports direct replacement installation without secondary modification, cutting down installation and commissioning time, reducing labor costs, and minimizing equipment downtime during maintenance and replacement.
8. Extensive Equipment Model Compatibility
Widely applicable to nearly all mainstream 10-20 ton construction machinery brands at home and abroad, covering excavators from John Deere, Case, Sany, Zoomlion, Sunward, Komatsu, Caterpillar, Hitachi, and loaders from XCMG and Liugong.
