Hydraulic Piston Pump – A Series
- High efficiency
Under the conditions of pressure 16 MPa (2320 PSI) and speed 1800 r/min, the volumetric efficiency is over 98% and the overall efficiency is over 90%. - Low noise level
In the “A16” pump, the noise level is as low as 57.3 dB(A) [at the full cut-off pressure 21 MPa (3050 PSI) with speed 1500 r/min one meter (3.3 ft.) horizontally away from pump head cover.] - Accomplishment of energy-saving
Because the overall efficiency is high and the cut-off characteristics are sharp, thus the input power may be saved. - Low heat generation
Because of the small power loss, it is possible to reduce the rise in oil temperature. Accordingly, capacity of a reservoir can be reduced.


Variable Displacement Axial Piston Hydraulic Pumps – AR Series
AR” series variable displacement pump has been developed which the aim of even further the quietness in operation, smaller in size and lighter in mass and based on Yuken technology and engineering which put on the market the “A” series pump which has a reputation for its quiet operation and high efficiency.
