The A4VSO125 is a compact hydraulic axial piston pump that offers a maximum pressure of up to 350 bar.
It has a displacement range of 28 to 125 cm³ per revolution, allowing it to deliver a wide range of flow rates. The pump is designed to work with a variety of hydraulic fluids, including mineral oils, environmentally friendly fluids, and water glycol.
Moving up in size, the A4VSO180 is a larger pump with a displacement range of 71 to 180 cm³ per revolution. It is capable of delivering higher flow rates and pressures, with a maximum pressure rating of 450 bar. Like the A4VSO125, it is compatible with various hydraulic fluids, making it versatile for different applications.
The largest of the three pumps is the A4VSO250, which has a displacement range of 125 to 250 cm³ per revolution.
It can provide even higher flow rates and pressures, with a maximum pressure rating of 500 bar. This makes it suitable for heavy-duty applications that require significant hydraulic power.
All three pumps utilize axial piston design, where the pistons are arranged in a circular pattern around a central drive shaft. This design ensures smooth and efficient operation, minimizing energy losses and maximizing output power. They feature variable displacement, allowing for precise control of the flow rate and pressure output. This makes them suitable for applications where varying hydraulic demands are required.
The pumps are equipped with a built-in pressure compensator, which adjusts the displacement according to the system's pressure requirements. This feature ensures that the pump delivers the required flow and pressure while minimizing energy consumption. Additionally, they have a through-drive capability, allowing them to be used as hydraulic motors in certain applications.
