Danfoss piston pumps, also known as axial piston pumps, work by converting mechanical energy into hydraulic energy. They consist of a cylinder block with several pistons arranged in a circle, and a swash plate that can be tilted to change the angle of the pistons.

When the pump is turned on, the swashplate tilts to a specific angle, causing the piston to reciprocate in its cylinder. As the pistons move forward, they draw hydraulic fluid into the cylinder through the inlets. As the pistons move back, they pressurize the fluid and force it out through the outlet port.

The pressure of the fluid is determined by the angle of the swash plate. Tilting the swashplate to a greater angle will increase the pressure, while tilting it to a smaller angle will decrease the pressure. The flow rate of the pump is determined by the speed at which the piston moves, usually controlled by a hydraulic motor or electric motor.

Danfoss piston pumps are commonly used in a variety of hydraulic systems, including construction machinery, agricultural machinery and industrial equipment. They are distinguished by high efficiency, low noise and long service life.

Danfoss offers a range of piston pumps in different sizes and specifications to suit different applications. Some key features of Danfoss piston pumps include:

1. Variable displacement: Danfoss piston pump can change the displacement by adjusting the angle of the swash plate, so as to realize precise control of hydraulic pressure and flow.

2. High efficiency: Danfoss piston pumps are designed to minimize energy loss and maximize efficiency, thereby reducing operating costs and reducing environmental impact.
