Vacuum pumps can be classified in four types according to mechanism on base pump works. The list of vacuum pumps types includes Positive displacement pump, Entrapment pump, Regenerative pump and Momentum transfer pump. All these industrial pumps are employing a different working principal and each has some unique advantages. In market variety of these pumps are available according to various capacities and features.
Vacuum pump is equipment that draws air or gas from a sealed chamber so that partial vacuum generates in it. Pumping process of gas is done in three ways such as positive displacement, momentum transfer and regenerative. In all three processes the gas is moving out from the inlet to the outlet of the pump.
Industrial vacuum pump is ideal solution to the challenges faced regarding wet processes like filtration, drying, condenser exhausting and vacuum distillation in many industries. These pumps are designed to handle gas, water and vapor. Industrial vacuum pump find an application in pulp & paper, sugar, petrochemicals, oil re-refining, food processing industries.
Vacuum pump was invented in 1650 by Guericke. He was a German politician and scientist. The first invented vacuum pump was a simple pump introduced from suction pump which already designed before. The industrial vacuum pump which is the most used today was originally developed by Robert Boyle and Robert Hooke.
