1 Swash plate design axial variable piston pump used in open circuit. 
2 Continuous work pressures can reach 280bar;
the highest instantaneous work pressure can reach 350bar.
3 The flow is directly proportional to the drive rotate speed and the displacement, 
and can make step less variable come true by adjusting the obliquity of the swash plate.
