Before technological advancements in manufacturing industrial vacuum pumps, it can be related as high oil carryover, consuming unreasonable energy costs and excessive noise. But with the developments made in air movement technologies, vacuum pumps became more reliable, operate quietly, and perform much better. If you are searching for this kind of equipment for your specific application, here is a short overview of the working principles and recent developments in the two major types of the industrial vacuum pump.
Rotary Vane Vacuum Pump
This type of vacuum pump is perfect to use in printing and paper industries. Rotary vane pumps operate using centrifugal force created by eccentrically attached rotor with moving blades. Some of the great developments made with this equipment are focused on improved performance and lower operating costs. The power demand of the latest units is about 15% lower than their predecessors and are more compact. The reliability of this industrial vacuum pump is because of its sturdy construction and better oil retention.
In addition, the incorporation of internal injection channels in the latest models helps reduce the amount of external piping needed and the number of gaskets required. In some units, the risk of leakage and failures are further minimised due to the reduction in components by about 20%. Rotary vane vacuum pumps are capable to operate at pressure range of 0.1 - 0.5 mbar. They are widely used in packaging, material handling, woodworking and plastics industries.
Liquid ring vacuum pump
If your application requires high volume of vacuum, a liquid ring pump perfectly suits you. This type of industrial vacuum pump is known to be great in handling extreme vapour loads and high tolerances for liquid carryover. Processes such as drying and distillation highly benefit in using liquid ring vacuum pumps. They work using a fixed blade impeller within a cylindrical casing. When in use, the impeller rotates to form the liquid ring around the casing.
Water is usually used to create the ring and seal the impeller, while creating enclosed gas chambers between the blades. The single stage pump models of liquid ring offer high efficiency of more than 200 mbar. These vacuum pumps are very useful in filtration and dewatering as well as evacuation duties.
