In a hydraulic system, an important constituent is the hydraulic pump. It has the very first purpose of creating fluid flow which in return gives power to various devices embedded within hydraulics. After drawing hydraulic fluid from a reservoir, it is pumped through different hydraulic lines, hoses and valves so as to provide the required force or motion. In case there is no hydraulic pump, no hydraulic system can work.
The working mechanism of a hydraulic pump is based on conversion of mechanical energy to hydraulic energy. The typical sources of power for this machine are electric motors, gasoline engines and diesel engines. There exist various types of hydraulic pumps like gear pumps, vane pumps and piston pumps amongst others. Some of these have their own advantages and disadvantages such as dissimilarities in efficiencies, fluid compatibilities and pressure capacities.
The main function of the hydraulic pump includes supply of necessary hydraulic pressure for actuating other components like cylinders and motors etc., these components are usually designed for doing some form of mechanical work such as lifting heavy loads or driving machinery. This ensures that reliable consistent fluid flow generated in hydraulic system can adequately accomplish these tasks.
