As we all know, piston pump has radial piston pump and axial pistonr pump two kinds. The following axial embolism pump manufacturer ZF hydraulic pressure is greatly different from radial piston pump, for your reference:

 

The plunger along the circumference of the radial distribution (plunger and drive shaft vertical) is the radial plunger pump. Plunger along the direction of the transmission shaft distribution (parallel to the transmission shaft) is the axial axial piston pump.

 

Axial piston pump and radial piston pump, high discharge pressure, it can generally work in the range of 20 ~ 50MPa, high efficiency, radial size, compact structure, small volume, light weight. But the structure is more complex than the radial piston pump, processing and manufacturing requirements are high, the price is more expensive.
