A hydraulic pump is a device that transforms mechanical energy into hydraulic energy to run various hydraulic systems used in many industrial and commercial applications.
These include gear pumps, vane pumps, and piston pumps; however, all types have some principles of operation in common.
By switching it on, the pump forms a void in the reservoir of the hydraulic fluid with the latter drawn into the inlet port of this pump. As soon as the mechanism for pumping starts rotating, pressure is created against this fluid with it being pushed out through an outlet port until it reaches a certain hydrostatic system.
The pressure produced by a pump depends upon its internal component sizes and shapes like gears or pistons. The speed at which a pump rotates determines how much hydraulic fluid passes through it per minute.
Typical sources powering hydraulic pumps are electric motors, internal combustion engines or other mechanical devices. A drive shaft or coupling links a power source to this pump.
Hydraulic pumps serve various systems including those driven by hydraulics such as cylinders, motors and valves. They are widely deployed in heavy machinery construction machinery and industry where high capacity outputs along with precise control features are demanded from hydraulics.
