The A11VO190 and A11VO145 are axial piston pumps, which means they use a rotating cylinder block with pistons arranged in a circular pattern to generate hydraulic pressure.
This design offers excellent efficiency and high power density, making them suitable for demanding applications like excavators.
Starting with the A11VO190, it is a robust pump with a displacement of 190 cc per revolution. The displacement refers to the volume of fluid the pump can deliver in one revolution. A higher displacement indicates a higher flow rate and more powerful performance. The A11VO190 is capable of delivering high-pressure hydraulic fluid up to 450 bar, allowing it to handle heavy-duty excavator operations.
The A11VO145, on the other hand, has a slightly smaller displacement of 145 cc per revolution. While it provides a slightly lower flow rate compared to the A11VO190, it still offers considerable power and efficiency. The maximum pressure rating for the A11VO145 is also 450 bar, ensuring reliable operation under demanding conditions.
Both pumps feature variable displacement control, which means the flow rate can be adjusted to match the specific requirements of the excavator.
This feature enables precise control over various functions, such as the movement of the boom, arm, and bucket. It also helps optimize energy consumption, reducing fuel consumption and operating costs.
To ensure durability and longevity, the A11VO190 and A11VO145 are constructed using high-quality materials and undergo rigorous testing. They are designed to withstand harsh environments and demanding work cycles commonly encountered in excavator applications. The pumps have robust bearings, pistons, and seals that can handle high pressures and provide reliable performance over an extended period.
Both pumps are also equipped with integrated pressure relief valves, which protect the hydraulic system from overpressure situations. This feature enhances the safety and reliability of the excavator by preventing damage to the pump and other hydraulic components.
Additionally, the A11VO190 and A11VO145 are designed for easy installation and maintenance. They have a compact and lightweight design, making them suitable for various excavator models and configurations. The pumps are also compatible with different types of hydraulic fluids, ensuring versatility and compatibility with existing systems.
