The Rexroth A4VG28DA is a compact and lightweight pump that belongs to the A4VG series.
It features a variable displacement axial piston design and is capable of delivering a maximum flow rate of 28 liters per minute. The pump has a maximum operating pressure of 350 bar and is designed for continuous duty applications. Its compact size and low weight make it suitable for mobile applications such as small construction machinery and material handling equipment.
On the other hand, the Rexroth A4VG250 is a larger and more powerful pump within the A4VG series. It offers a variable displacement design and has a maximum flow rate of 250 liters per minute. The pump can operate at a maximum pressure of 450 bar, making it suitable for heavy-duty industrial applications. The A4VG250 is commonly used in various industries, including mining, marine, and oil and gas.
Both pumps feature a swashplate design, which allows for a wide range of displacement adjustment. The displacement can be easily changed by adjusting the swashplate angle, providing flexibility in meeting different flow requirements. This feature makes the pumps suitable for applications with varying load demands.
The A4VG28DA and A4VG250 pumps are designed for high efficiency and energy savings.
They incorporate advanced hydraulic technologies, such as pressure compensation and load sensing, to optimize performance and reduce energy consumption. These pumps also have low noise levels, ensuring a quieter working environment.
The piston design of these pumps ensures excellent durability and longevity. The pistons are made from high-quality materials and are precision-engineered to withstand high pressure and heavy loads. This ensures reliable operation even in demanding conditions, minimizing downtime and maintenance costs.
Both pumps can be configured with various control options to suit specific application requirements. They can be equipped with electronic control units that provide precise control and monitoring capabilities. This allows for integration with modern control systems and enables advanced features such as speed control, pressure regulation, and system diagnostics.
