Hydraulic
pumps deliver high-pressure fluid flow to the pump outlet. Powered by
mechanical energy sources, the hydraulic pumps make use of gears, vanes,
pistons and various other devices to pressurize fluid. When they are
powered by pressurized fluid, the pumps rotate in a reverse direction
and act as a motor. Hydraulic pumps have applications in all types of low and high-pressure testing and oilfield uses such as removing cores from core barrels and testing valves, fittings. They are simple to construct and operate and are quite flexible with excellent performance.
