What is YCY Axial Piston Pump

YCY piston pump is a type of variable displacement axial piston hydraulic pump commonly used in industrial and heavy machinery applications. It features pressure compensation, high efficiency, and a compact design, making it suitable for systems requiring precise flow control and high pressure.

The "Y" in the designation typically indicates that the pump features a constant pressure compensation control mechanism.

How it Works

The pump operates on the axial piston principle. As the cylinder block rotates, the pistons move back and forth within the cylinder bores. The "Y" (constant pressure) control works by automatically adjusting the angle of the swash plate:

  • When system pressure is low: The swash plate remains at its maximum angle, providing maximum flow.

  • When system pressure reaches a set point: The pump automatically reduces the swash plate angle (decreasing flow) to maintain that specific pressure level.

  • At the pressure limit: If the system doesn't require flow, the pump moves to "zero-stroke," maintaining pressure while consuming minimal power.



YCY Axial Piston Pump Application

The YCY pressure compensated variable axial piston hydraulic pump distributes hydraulic oil through a swash plate and cylinder. Compared with other types of pumps, its unique hydrostatic balance structure between the swash plate and the pump cylinder has the advantages of simple structure, compact size, high efficiency, long life, lightweight design, and strong self-priming ability.


YCY hydraulic piston pump is mainly used in hydraulic transmission systems such as hydraulic machinery, forging, metallurgy, engineering, and mining. It is easy to maintain and generally only needs to replace the piston or swash plate and other pump components.
