In commercial settings, hydraulic pumps are sometimes employed in the supply of hydraulic fluid to elevators. Hydraulic pumps can also be used in several different consumer products contexts. In rural residences, hydraulic water pumps are often used to transmit water from wells to consumer utilities such as faucets and washing machines.
Some of these hydraulic pumps are examples of gear pumps. Gear pumps can be operated in a number of ways. Electric hydraulic pumps are often equipped with gears as a method of transmitting liquid from one area to another. Many other gear pump varieties are powered by gas motors. Hydraulic gear pumps are used in the automotive, agricultural, construction, defense contracting and manufacturing industries.
There are two main hydraulic gear pump varieties: external gear pumps and internal gear pumps. External gear pumps feature two spur gears, both of which gears’ spurs are externally oriented. Internal gear pumps also have two spur gears, each gears’ spurs are internally oriented, with one gear rotating around inside of the other gear.
Both kinds of gear pumps supply a regular amount of liquid for every rotation of the gears. Hydraulic gear pumps are favored because of their relatively simple design, their versatility and their effectiveness. Also, because they are available in multiple configurations, they can be applied in a wide variety of contexts in industry as well as in commercial and consumer products contexts.
Because of the wide variety of contexts in which hydraulic pumps are used, and because of the varying kinds of tasks that require the use of pumps within each of those contexts, the demand for hydraulic gear pumps, as well as many other hydraulic pump varieties, is likely to remain for the foreseeable future.
