Chemical Pumps

Operation Principles of Chemical Pumps

Chemical pumps are a crucial element in modern technologies, playing a key role in substance transfer across various industries.

The primary task of chemical pumps is the precise and efficient transfer of substances. These pumps operate based on various principles such as displacement, centrifugal force, and others. Their role in chemical processes cannot be overstated, as they ensure reliable transportation of chemical substances.

Application of Chemical Pumps

Chemical pumps find wide applications in industries. In the chemical sector, they facilitate the transfer of chemical reagents, in the oil and gas industry, they transport petroleum products, and in electronics manufacturing, they convey liquids for semiconductor production.

They are also utilized in the medical field, playing a crucial role in the operation of medical devices and ensuring the transportation of medical fluids.

Chemical pumps remain an essential component of modern technologies. Their role in industry and medicine, coupled with ongoing research and innovations, makes them a key element for future advancements in scientific and technical progress.

Types of Chemical Pumps

One type of chemical pump is the magnetic drive pump, utilizing magnetic field forces to transfer energy to the rotating pump rotor. This eliminates the need for pumping through the pump shaft seal, preventing fluid leakage. A notable advantage of this pump type is the absence of liquid leakage, particularly crucial when transferring aggressive and hazardous substances.

Another type is the air-operated diaphragm pump, driven by compressed air. Equipped with a flexible diaphragm, it compresses and expands under the pressure of compressed air, displacing the liquid through the pump. These pumps are also used for transferring aggressive and hazardous substances due to their complete seal.

There are also chemical pumps with electric motor drive, usually equipped with sealed seals to prevent leaks. These pumps can be designed to operate in aggressive environments.

Chemical pumps may vary in drive type, sealing, and the ability to work with aggressive substances. The choice of the right type depends on specific conditions.
