Dry vacuum pumps do not use any type of fluid to create a vacuum or contact the process gas. Their design is characterized by timing gears with oil reservoirs and close clearances between the rotors and housing. All types of dry vacuum pumps run hot, as there is no liquid to remove the heat created by compression of the gas. Engagement of a cooling jacket to normalize the dry vacuum pump’s internal temperature is done to prevent excessive heating of the pump, which could cause pump failure. Cast iron or ductile iron are low-cost materials of construction, which provide an economical advantage to the manufacture of dry vacuum pumps. This has also been leading to affordable costs and thereby increased popularity of dry vacuum pumps, along with the added benefit of limited rise of heat inside them.
Dry running vacuum pumps find applications where there is, a growing demand for uncontaminated vacuum i.e. free from oil or service liquid, a requirement for low operating pressures, a flexibility required from batch processes, concern about storage and disposal costs of service liquids and the pressure to minimize life-cycle costs.
As dry vacuum pumps run hot, they possess the ability to handle corrosive vapours even with usage of standard iron as their material of construction. This is so because, corrosion normally occurs in moist condition, which is absent in the case of functioning of dry vacuum pumps.
Considering the numerous advantages of dry vacuum pumps and their multiple applications across industries, the study of global dry vacuum pumps market becomes an important read.
