Features
High efficiency • Low noise level
Under the conditions of pressure 16 MPa (2320 PSI) and In the "A16" pump, the noise level is as low as 57.3 dB(A) speed 1800 r/min, the volumetric efficiency is over 98% [at the full cut-off pressure 21 MPa (3050 PSI) with speed and the overall efficiency is over 90%. 1500 r/min one metre (3.3 ft.) horizontally away from pump
head cover.]

Accomplishment of energy-saving
Because the overall efficiency is high and the cut-off characteristics is sharp, thus the input power may be saved.
Low heat generation
Because of small power loss, it is possible to reduce the rise in oil temperature. Accordingly, capacity of a reservoir can be reduced.
