Air Ejectors

The operating principle of jet vacuum pumps consists of the ejection of a liquid or gaseous jet at high speed from a nozzle in which the liquid, gas or solid is extracted from its surroundings, accelerated and entrained in the jet. The field of activity of Arpuma is restricted to vacuum pumps whereby exclusively gas jet, steam jet and liquid jet vacuum pumps are employed.

The gas jet vacuum pump is often operated in combination with a liquid ring vacuum pump. In this way the intake pressure of the liquid ring vacuum pump can be further reduced, this often being necessary in connection with drying processes, for example.

A further application is its use together with liquid ring vacuum pumps which are operated with operating liquids at high vapour pressures. In the case of steam jet and liquid jet vacuum pumps, steam, respectively a liquid is as the name already implies used as the propellant. High-quality materials of construction permit pumping of even highly corrosive media.
