First, product performance and use: axial piston pump is the direction of the reciprocating motion of the piston or plunger and the cylinder parallel to the central axis of the piston pump. The axial piston pump is working volume variation generated by the reciprocating motion of the plunger bore parallel with the drive shaft of the plunger. As the plunger and plunger holes are circular parts, processing can achieve high accuracy with high volumetric efficiency, smooth operation, flow uniformity, low noise, and high working pressure, but the hydraulic oil pollution more sensitive, more complex structure, a higher cost.
