[Features]
High efficiency
Under the conditions of pressure 16MPa(2230PSI) and
speed 1800r/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 57.3dB(A)
[at the full cut-off pressure 21MPa(3050PSI) with speed 1500r/min one metre(3.3ft)
horizontally away from pump head cover.
Accomplishment of energy-saving
Because the overall efficiency is high and the cut characteristics is sharp,
thus the input power may 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.
