The A7V080 and A7V080LRHT belong to the A7V Series of axial piston variable displacement pumps, manufactured by Rexroth, a leading provider of hydraulic solutions.
These pumps are widely used in mobile and industrial hydraulic systems, including construction machinery, mining equipment, marine applications, and more.
One of the notable features of the A7V080 and A7V080LRHT pumps is their variable displacement capability. This means that the pumps can adjust their output flow rate based on the system requirements, providing the precise amount of hydraulic fluid needed. This feature enhances energy efficiency and allows for better control over the hydraulic system.
The A7V080 and A7V080LRHT pumps have a maximum operating pressure of up to 450 bar (6,527 psi), which makes them suitable for high-pressure applications. These pumps are designed to handle demanding operating conditions and deliver consistent performance even under heavy loads. The rugged construction and high-quality materials ensure durability and long service life.
The displacement of the A7V080 pump ranges from 71 cc/rev (4.34 cu in/rev) to 140 cc/rev (8.54 cu in/rev), while the A7V080LRHT pump offers a displacement range from 71 cc/rev (4.34 cu in/rev) to 107 cc/rev (6.53 cu in/rev). The choice of displacement allows for flexibility in meeting different flow rate requirements of hydraulic systems.
These pumps feature a swashplate design that enables precise control of the output flow.
The swashplate angle can be adjusted to regulate the pump displacement and, consequently, the flow rate. This design allows for smooth operation, low noise levels, and efficient power transmission.
The A7V080 and A7V080LRHT pumps are equipped with a load-sensing control system. This system adjusts the pump output to match the demand of the hydraulic system, reducing energy consumption and minimizing heat generation. The load-sensing feature also ensures quick response times and improved system efficiency.
To enhance reliability and minimize maintenance requirements, these pumps incorporate various protective measures. They are equipped with integrated pressure relief valves that safeguard the hydraulic system from overpressure situations. Additionally, the pumps have a built-in charge pump for self-lubrication and cooling, ensuring continuous operation and preventing damage caused by insufficient lubrication.
The A7V080 and A7V080LRHT pumps are compatible with a wide range of hydraulic fluids, including mineral oils, synthetic fluids, and environmentally friendly biodegradable fluids. This compatibility allows for flexibility in choosing the appropriate fluid for specific applications, considering factors such as temperature, viscosity, and environmental regulations.
