Excavator Hydraulic Pump

The DPA pump series are developed for construction equipments, especially with high quality by functional design.
And they enjoy user’s confidence thanks to high output density and efficiency through optimization of structure provided by various bench tests and computer simulation 
Axially Compact The total length of DPA series is 30% shorter than theconventional tandem pump of same class of displacement. Wide Range of Control DPA series can be controlled by hydraulic input either negative pilot pressure or positive one.
Beside,it is capable of responding to electrical input signal.
