A Hydraulic Pumps is a mechanical pump. It uses the kinetic energy of flowing water to push a small part of water to a higher level. It is a mechanical device that moves liquid in a hydraulic system.

It can be mainly divided into hydrostatic and hydrodynamic. The former is a positive displacement pump. Unlike static pressure pumps, the latter pumps can be of fixed displacement, in which case the displacement cannot be adjusted. At the same time, the structure of the hydraulic pump is more complicated, and the displacement can be adjusted according to the special needs of the user.

How does a hydraulic pump work? It works according to Pascal's law, which states that "pressure in a static hydraulic fluid in a closed system is everywhere". Generally, in a hydraulic pump, water or another fluid is highly pressurized and moved by various motors and cylinders. In order to control the fluid, various valves, hoses and tubes can block or disperse the fluid, so that pressure and force can be generated without external power supply. By using the kinetic energy (molecular energy) of water / fluid to power the pump, no electricity is needed. According to the law, if you increase the pressure in a certain area of ​​the system, the pressure on the entire system will increase.

Of course, like many other types of pumps, hydraulic pumps also have a wide range of applications. Its application can be summarized as the transfer and circulation of liquids in light industry and agricultural irrigation and pressurization. It can also be applied to tin cooling systems and air conditioning systems.

In daily applications, especially in hydraulic installations, one pump can power more cylinders and electric motors. However, the ensuing problem is that in this case, a constant voltage system is required, and the system always requires full power. A more economical way to solve this problem is to assign its own pump to each cylinder and motor.

Hydraulic pumps include gear pumps, screw pumps, curved shaft pumps, peristaltic pumps, etc. All these different types of pumps have many common features. Most of them are designed to be ideal for water supply, irrigation, commercial and industrial use. In addition, they are mostly made of cast iron and brass. Taking a gear pump as an example, in the simplest system, the pressure is usually kept low, which is the most common situation. They are simple, reliable, and less sensitive to dirt.
