Otto von Guericke invented vacuum pump in the year 1650. His study involved making a vacuum to remove gas from an enclosed chamber. Today, with the ever-growing stature of technology, several models of vacuum pumps have evolved that serve varying purposes. However, for optimal operational efficiency, it is imperative to choose the right kind of vacuum pump. Just like every requirement is unique, the vacuum pumps also have unique features and functionalities. As a buyer, you need to know the exact type of vacuum system that would fit your bills offer and offer you the best benefit. Some of the popular types and functionalities of vacuum pumps are mentioned below-
Positive Displacement Pump: Positive displacement pumps are the models which are used to expand the volume. The high power density of these vacuum systems is their strongest advantages. These pumps are considered as the most economic and efficient fluid handling system.
Momentum transfer pump: these vacuum pumps are designed to achieve high vacuums. Momentum transfer pumps utilize metallic fins or vapor stream to strike the incoming molecules of gases and impart a momentum which transfer the molecules to the pump’s outlet. Momentum transfer pumps include diffusion pumps and turbomolecular pumps.
Entrapment pump: These pumps seize gases in an adsorbed or solid state. These include cryopumps, ion pumps and getters. Cryopumps use cold temperature to abbreviate gases to a solid or adsorbed state. Chemical pumps blend with gases to bring out solid residue and ion pumps use strong electric fields to ionize gases and disperse those ions into a solid substrate.
For optimal result, it is smart to recognize your unique needs and consult with the manufacturer and select the machine that will suit your needs to the best.
