In a hydraulic system, fluid is conveyed through the various components by the activity of a pump. Pumps work by converting mechanical energy—e.g., the turning of a gear—into hydraulic (i.e., fluid) energy. Hydraulic pumps may be either fixed displacement (conveys a precise, unchangeable amount of fluid during each rotation) or variable displacement (can be altered to change the amount of fluid conveyed). Of these two types, variable displacement pumps are more complicated in design and, therefore, tend to be more expensive.
Hydraulic pumps are used in a wide range of industrial equipment and, for this reason, they exist in a broad assortment of designs, including the following:
Vane pumps – Vane pumps feature a rotating shaft with a number of thin vanes protruding from it. The vanes effectively separate the housing into distinct compartments, each of which conveys fluid from the input to the output as the central rotor turns. Because the rotor is positioned eccentrically, its motion first steadily increase the volume of space in each compartment as the compartments fill and then decreases them as they empty when the fluid is forcefully expelled through the output.
Gear pumps – The typical gear pump has two interlocking gears, one of which is connected to a drive shaft. As the shaft turns, the two gears are put into motion, conveying the hydraulic fluid around the outer perimeter of the housing and finally through the outlet.
Piston pumps – A piston pump is characterised by the presence of one or more pistons, consisting of a cylinder inside a cylinder. The up-and-down motion of the piston conveys hydraulic fluid to the output. These pumps are available in axial and radial designs.
