Ejectors for OMEL Vacuum Pump

For high vacuum pumps, OMEL has developed a gas ejector, which has, among other operating advantages, the non-use of external energy, as it uses the pressure difference between the atmosphere and the pump’s suction pipe.

The maximum vacuum achieved by a liquid ring vacuum pump depends, among other factors, on the vapor pressure of the auxiliary liquid at the pumping temperature.

However, the maximum vacuum corresponding to this vapor pressure cannot be reached without the liquid boiling.

Project Features

Body/housing in cast iron or stainless steel. The ejector can be manufactured in other alloys;
Designed and manufactured according to each vacuum pump model to deliver maximum performance;
There is no need for heat exchangers (intercoolers). The resulting gas mixture leaving the ejector is cooler than the inlet temperature, so a heat exchanger is not needed after a Roots-type vacuum pump if one is being used;
The discharge gas of the liquid ring vacuum pump can be used as the driving gas for the ejector;
When disassembling the pump, it is not necessary to disassemble the ejector;
If the ejector is properly sized, the vacuum breaker valve can be eliminated.

Advantages

Higher vacuum levels can be easily achieved;
The ejector is a simple part, it practically does not wear out and its erosion is negligible;
It does not take up space and does not require auxiliary pipes;
It does not require external energy as it uses the pressure difference between the atmosphere and the pump’s suction pipe.
