CY Series Axial Piston Pumps 25YCY14 40YCY14 63YCY14 80YCY14
Features
Structure
The CY series are axial piston pumps, distributing oil via a valve plate with a rotating cylinder block.
Advantages
Featuring hydrostatic balance structures, they're simple, compact, efficient, long-lasting, lightweight, and have strong self-priming.
Applications
Suitable for machine tools, forging, metallurgy, engineering, mining, and other hydraulic systems.
Versatility
Can be used as hydraulic motors by changing the motor oil distribution plate.
