The Hydraulic Piston Pump is one of the most versatile, efficient and stronger pump that it is on the market in these days. Because of the way it is designed, it can be fixed or variable displacement. The variable displacement hydraulic piston pump has in general two major components, the rotating group and the control. |

The rotating group consists of: Pressure plate, Piston Barrel, Pistons, Piston Shoes, Swash plate and Drive Shaft. The pistons travel inside the barrel bores sucking and pumping oil while the rotating group rotates.
The Control, also called compensator is generally an external element attached to the case. There are many variations of a compensator, some of them very complex, but we can say that in general it controls the maximum pressure, the flow that the pump delivers and in other cases the maximum power.
The compensator is capable of those features because it controls the position of the swash plate, or in other words it controls the angle of tilting according to the demands of the hydraulic system. |
