The use of hydraulic systems is common in Indonesia, both for industry, machinery, vehicles, automotives and so on. Hydraulics certainly have great power and power so they can lift very heavy loads.
This hydraulic system relies on various supporting components, one of which is a piston pump. The piston pump has two types, namely the Axial piston pump and the Radial piston pump. Both of these pumps are positive displacement pumps, and have high efficiency. The output of these two pumps can be fixed (fixed) and can also be variable (changeable). In the fixed displacement Axial Piston Pump, the piston moves straight forward and backward parallel to the shaft.
