Hydraulic Piston Pumps Axial Plunger Pump CY Series 25SCY14-1B
The CY series are axial piston pumps, distributing oil via a valve plate with a rotating cylinder block.
Featuring hydrostatic balance structures, they're simple, compact, efficient, long-lasting, lightweight, and have strong self-priming.
Suitable for machine tools, forging, metallurgy, engineering, mining, and other hydraulic systems.
Can be used as hydraulic motors by changing the motor oil distribution plate.
