Before proceeding to know the meaning of the term hydraulic pump, it is necessary to discover the etymological origin of the two words that give it its shape. Specifically, it is the following:
-Bomba is a word that comes from the French “bombe” and the Italian “bomb”. However, these are derived from a Latin, from “bombus”, which can be translated as “strong and intense sound”.
-Hydraulics, on the other hand, is a term derived from the Greek “hydraulikos” which meant “musical organ”. That word that is the result of the sum of the noun “hydor”, which is synonymous with “water”, and of the noun “aulos”, which is equivalent to “flute”.
According to DigoPaul, the term pump can be used in a number of ways. In this opportunity we will stay with its meaning as the device that allows a liquid to be pushed in a certain direction. Hydraulic, on the other hand, is that which moves by the action of a fluid or the energy that is generated from the movement of water.
Therefore, it is called a hydraulic pump to the machine that is responsible for transforming the mechanical energy that allows its operation into the energy of an incompressible fluid that it itself displaces. As the energy of this fluid increases, it also increases its height, its velocity or its pressure. This is why hydraulic pumps are used to move the fluid from a place of lower altitude or pressure to another with higher altitude or pressure.
It is possible to refer to different types of hydraulic pumps according to their drive or operation. There are manual pumps, such as the rocker pump, in which one person must exert force. Also hydraulically driven pumps (such as a Ferris wheel), pneumatic pumps (energy is provided by compressed air) and electric pumps (an electric motor is responsible for driving them).
In addition, volumetric pumps (which are based on hydrostatics) and rotodynamic pumps (focused on hydrodynamics) can be named.
Of course, it is important to know, for example, that volumetric pumps, for their part, are in turn divided into two different types:
-Rotary volumetric pumps. They are also known as rotostatic and are defined by being those in which a fluid mass is found within one or more compartments that are the ones that move from the entrance to the exit. These include, for example, screw pumps.
-The reciprocating plunger pumps. This is the name given to hydraulic pumps in which there are several fixed compartments that have a variable volume. In these, what is the plunger as well as the valves that open and close alternately play a fundamental role.
With a hydraulic pump, you can draw water from a well or make running water reach the highest floors of a building, to name a few of the possibilities these machines provide.
