"A" SERIES PISTON PUMPS

Variable Displacement-Sindle Pump

Pressure Compensator



The A series piston pumps are widely used in various machinery with hydraulic systems like plastic machine, shoe machine, CNC machine, etc. It is energy-efficient and low-noise.

1.Whenener setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent pressure.

2.Care should be taken in cases of used any a higher pressure than the rated pressure, because operating terms may be restricted. For example, if used as per maximum illustrated operating conditions, intermittent time at maximum flow is restricted to under 1/5 of one cycle time and under 6 seconds simultaneously. Conditions may vary according to the actual working pressure and delivery.



The specification of our Hydraulic Pumps and Valves is the same with Yuken's, but the price is more attractive. We have our own factory in Taiwan. Our product quality is better than those made in China.
