The physical properties of the sealing oils mean that they do not degrade even at high operating temperatures This considerablly increases the performances of a liquid ring pump compared to a pump operating with water.
The vapor pressure which is considerably lower than that of water at 15°C and the perfect sealing of the liquid ring allow a high and constant vacuum, even at high gas temperatures.
Thanks to the recirculation of oil in the pump and the use of a very low power air/oil exchanger the consumption of water can be totally eliminated. This means great savings in operating costs.
The circulation oil continually lubricates the internal parts of the pump without leaving deposits of any kind. This protects the pump components from wear and prolongs their operating life. The service and maintenance intervals are long, keeping life cycle costs low.
The exclusive built-in systems for separating the extracted condensate from the service oil enables the removal of high percentage of vapor-saturated gas. The clean condensate is then discharged.
Noise levels are much lower than demanded by law.
