Hydraulic Pump A4VG180EP3

The A4VG180EP3 is a high-performance axial piston variable pump designed for open hydraulic systems in mobile equipment, widely used in mining, railway engineering vehicles, and other heavy machinery. Featuring a swashplate design, it offers a displacement range of 40 to 260ml/rev and a nominal pressure of 350bar. The externally adjustable power control allows real-time adjustments even during operation. Its through-drive design supports integration with gear pumps and axial piston pumps, enabling 100% through-shaft power transmission. Multiple control combinations are available to meet diverse equipment action requirements. Weighing 101kg with a flow rate of up to 450L/min, the pump is compact and optimized for efficiency, significantly reducing equipment energy consumption.

The A4VG180EP3 product operates on the principle of an axial piston variable pump. This type of pump is designed to provide a variable flow rate, which can be adjusted according to the system's requirements. The pump consists of a cylinder block with multiple pistons arranged in a circular pattern, a swash plate that controls the angle of the pistons, and a control valve that regulates the flow of oil into and out of the pump.

During operation, the pistons move back and forth within the cylinder block, creating pressure differences between the inlet and outlet ports. The swash plate adjusts the angle of the pistons, which in turn changes the volume of the chambers formed between the pistons and the cylinder block. By controlling the flow of oil through the control valve, the pump can maintain a constant pressure while varying the flow rate.

This variable displacement design allows the A4VG180EP3 to optimize efficiency and reduce energy consumption by adjusting the flow rate according to the system's needs. It is well-suited for heavy-duty applications where precise control and high performance are essential.
