Hydraulic pumps are sources of power for many dynamic machines. Hydraulic pumps are capable of pushing large amounts of oil through hydraulic cylinders or hydraulic motors. In this fashion, the pump converts the mechanical energy of the drive (i.e. torque, speed) into hydrostatic energy (i.e. flow, pressure). You can use hydraulic machines - equipped with a pump - to do different types of work such as lift, lower, open, close or rotate components.
Hydraulic pumps operate according to the displacement principle. This involves the existence of mechanically sealed chambers in the pump. Through these chambers, fluid is transported from the inlet (suction port) of the pump to the outlet (pressure port). The sealed chambers ensure that there is no direct connection between the two ports of the pump. As a result, these pumps are very suitable to operate at high system pressures and are ideal for hydraulics.
Hydraulic pumps are manufactured depending on different functional and hydraulic system requirements, such as operating medium, required range of pressure, type of drive, etc. A large range of design principles and configurations exists behind hydraulic pumps. Consequently, not every pump can fully meet all sets of requirements to an optimum degree. Three different types of hydraulic pumps exist: gear pumps, piston pumps and vane pumps.
Gear pumps have very few moving parts, work smoothly, and operate very well at pressures around 210 bar. It is the pump with higher speeds up to 3000-6000 rpm.
Hydraulic piston pumps handle very large flows at high hydraulic system pressures. Applications are mobile and construction equipment, marine, offshore and industrial.
Hydraulic vane pumps operate with much lower flow pulsation, i.e. constant flow. As such, vane pumps produce less noise while maintaining a high speed.
