To ensure consistency and quality throughout the entire assembly process, every manufacturing unit is equipped with machines that operate on vacuum systems. A vacuum system necessarily comprises of vacuum pumps. Vacuum pumps are devices that work on the principle of removal of gaseous molecules from a fixed volume and thus creating a vacuum. Vacuum pumps come in several diverse types of models and varieties with different mechanisms and applications but their fundamental principle remains constant.

The segment of rotary vane pumps are included in these vacuum pumps. A rotary vane pump is a positive-displacement pump consisting of vanes attached to a rotor that rotates inside the cavity. This causes a vacuum in the center of the pump creating a suction and a void. To fill this void water or other fluid enters into the pump via an inlet valve. Once the fluid is inside the pump, the intake valve shuts and subsequently the outlet valve opens up. These series of events allow the fluid to flow back outside through another path.

Rotary vane vacuum pumps are of two different types. The non-lubricated pump, also referred ...
... to as an “oil-free” pump while other type is lubricated pump. Both the types of rotary vane vacuum pumps operate on the same theory but used for different applications.

Rotary vane pumps are one of the most widely used vacuum pumps in manufacturing industry. Their most common use in daily life is removal of water from the basement of buildings. The rationale for using a vacuum pump is, water needs to be moved upwards and this is possible only by creating enough vacuum that will eventually draw the water inside the pump and then push it uphill into the outer area.

Since countless years now, these pumps have been providing revolutionary changes across industries and enriching millions of lives.
