The Rexroth A4V series is a variable displacement axial piston pump that offers precise control over fluid flow.
It is available in various frame sizes and displacement options, allowing for flexibility in system design. The A4V pumps are designed to operate at high pressures and are capable of delivering high flow rates, making them suitable for demanding applications. These pumps feature a swashplate design that enables the adjustment of the displacement angle, providing variable flow rates and allowing for energy-efficient operation.
The A4VT series is a variation of the A4V series, designed specifically for mobile applications. These pumps are characterized by their compact size, lightweight construction, and excellent power-to-weight ratio. The A4VT pumps are built to withstand harsh operating conditions commonly encountered in mobile machinery such as excavators, loaders, and cranes. They offer excellent efficiency, low noise levels, and long service life, ensuring optimal performance in demanding mobile hydraulic systems.
The A4VTG series is a further development of the A4VT series, featuring integrated electronics for advanced control and monitoring capabilities.
These pumps incorporate sensors and electronic components that enable precise control of flow and pressure. The integrated electronics also provide diagnostic functions, allowing for real-time monitoring of pump performance and facilitating predictive maintenance. The A4VTG series is ideal for applications that require advanced control features and enhanced system performance.
Now, let's focus on the A4VTG71 hydraulic pump, which is a specific model within the A4VTG series. The A4VTG71 pump offers a displacement range of 71 cc/rev and is designed for medium to high-pressure applications. It can operate at pressures up to 400 bar (5800 psi) and delivers a maximum flow rate of 185 liters per minute (49 gallons per minute). The pump is constructed with high-quality materials and precision manufacturing techniques to ensure durability and reliability.
The A4VTG71 pump features a compact design, allowing for easy integration into hydraulic systems with limited space. It offers excellent volumetric efficiency, minimizing energy losses and reducing operating costs. The pump is equipped with a through-shaft design, enabling multiple pumps to be mounted in tandem for increased flow and redundancy. It also incorporates a load-sensing control mechanism, which adjusts the pump displacement according to the system demand, further enhancing energy efficiency.
