From the pump performance range, the flow rate of the giant pump can reach several hundred thousand cubic meters per hour, while the flow rate of the micro pump is below several tens of milliliters per hour; the pressure of the pump can be from normal pressure to up to 19.61Mpa (200kgf/ Cm2) or more; the temperature of the liquid to be transported is at least -200 degrees Celsius, and the highest is above 800 degrees Celsius. Pumps transport a wide variety of liquids, such as transport water (clean water, sewage, etc.), oil, acid and alkali, suspension, and liquid metal.
In the chemical and petroleum sectors, raw materials, semi-finished products and finished products are mostly liquids, and the preparation of raw materials into semi-finished and finished products requires a complicated process in which the pump acts as a pressure source for transporting liquids and providing chemical reactions. In addition, in many devices, pumps are also used to regulate the temperature.
In agricultural production, pumps are the main irrigation and drainage machinery. China's rural areas are vast, and every year, a large number of pumps are needed in rural areas. Generally, agricultural pumps account for more than half of the total pump output.

Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to use pump drainage. In the process of mineral processing, smelting and rolling, it is necessary to use a pump to supply water first.
In the power sector, nuclear power plants require nuclear main pumps, secondary pumps, tertiary pumps, and thermal power plants that require a large number of boiler feed pumps, condensate pumps, circulating pumps, and ash pumps.



In the construction of national defense, the adjustment of aircraft flaps, tail rudders and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines require pumps. High pressure and radioactive liquids, and some require pumps without any leakage.
In the shipbuilding industry, the pumps used on each ocean-going wheel are generally more than one hundred, and the types are also various. Others such as urban water supply and drainage, water for steam locomotives, lubrication and cooling in machine tools, transporting bleaching and dyeing in the textile industry, conveying pulp in the paper industry, and transporting milk and sugar foods in the food industry require a large amount of pump.

In short, whether it's airplanes, rockets, tanks, submarines, or drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are everywhere. That's it, so the pump is listed as a general-purpose machine, which is a kind of raw product in the mechanical industry.
