Vanes

Vanes are rotary discs that allow the creation of suction for the removal of air molecules from a vessel or a specific area. A rotary disc vacuum pump operates on a positive displacement pumping principle. It consists of a rotor mounted in a cylindrical housing. 

What are vanes?

A vane is part of a rotary vane vacuum pump. The rotary vane vacuum pump is characterized by oil-free operation and high operating reliability. Because they are oil-free, they are ideal for industrial applications requiring fast and reliable vacuum.

Operation dry-running rotary vane vacuum pump:

A rotary vane vacuum pump operates on a positive displacement pumping principle. It consists of a rotor mounted in a cylindrical housing. A vane is also called a vacuum vane.

  1. The dry-running rotary vane vacuum pump consists of a cylindrical pump housing assembled with an electric motor.
  2. Inside the pump housing is an eccentrically arranged rotor with vacuum vanes.
  3. As the rotor rotates in the pump housing, the vacuum vanes move toward the pump housing wall (centrifugal force), creating chambers in the 360-degree circle.
  4. Air is drawn in, compressed and pushed out again.
  5. The pump sucks in this way allowing a vacuum to build up.

Types of vanes

A vane is a turntable that allows the creation of suction for the removal of air molecules from a vessel, machine or specific area. These vacuum pumps are widely used for the food, pharmaceutical and medical industries.

There are different types of vanes:

  • Carbon vanes
  • Steel vanes
  • Plastic vanes

Carbon vanes can only be used for dry-running vacuum pumps. Steel and plastic vanes are also suitable for oil-lubricated vacuum pumps. The service life of a vane depends, among other things, on the environment in which the dry-running vacuum pump is located. A wet, dirty, very hot or just cold environment can indeed shorten the life of the vane.
