Hydraulic (liquid pressure) is generated by the pump. There are a variety of pumps: vane pumps, gear pumps, screw pumps, piston pumps, ....... There are a number of different structures in each type. You ask piston pump, there are multiple styles, structures. The radial, axial, single plunger multi plunger, ....... They have one thing in common: The plunger plug in the hole, the plunger reciprocates in the hole hydraulic motor (like bellows as) a hydraulic motor repair, oil, drain. Put the pressure of pressurized oil into the oil. Mainly used in hydraulic systems, construction machinery vehicles aspect maintenance of hydraulic motors, hydraulic motor parts, such as excavator, truck, loader, garbage vehicles, and so on. Also used in a variety of pumps, such as: high-pressure plunger pump, reverse osmosis pumps, injection pumps, large-scale high-pressure pump, injection pump, high pressure slurry pump, pump gas drilling atomization, pressure injection pump, high-pressure water gun, oil drilling pumps, diesel driven pump, the three high-pressure plunger pumps, mills and phosphorus removal pump, high pressure fire pumps, desulfurization and denitrification pumps, high pressure cleaning pumps, chemical pumps, and so on.
