Under the conditions of pressure 16 MPa (2320 PSI) and speed 1500 r/min, the volumetric efficiency is over 98% and the overall efficiency is over 90%.
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.
