A.) High volumetric efficiency is
more than 95%.
B.) Power consumption is 30% less than machines haying fixed
displacement pump.
C.) Cooling water requirement of hydraulic oil is between 1/3 and 1/2
of fixed pump requirement due to without extra hydraulic oil overflow.
Therefore there is longer life for the seal of pump than fixed pump.
D.) On the basis of proportional technology, the combination of
electrical and sensor technology reaches the success of dosed loop
variable pump. Through the control of pressure and flow by proportional
valve, and continual monitoring on pressure and flow by pressure sensor
and plate angle sensor, it leads precise pressure and flow to save
energy.
E.) There is great characteristic curve on input voltage & pressure
and almost direct proportion on the characteristic curve on input
voltage & flow. Closed loop control is adopted so pressure and flow
can be adjusted well by voltage. Energy saving become great due to high
precision control and high respond.
