Single and two-stage rotary vane pumps - rugged and long-life

The use of gas ballast has different impacts on the performance data of pumps. The pumping speed reached by single-stage rotary vane pumps, for example, is reduced by the proportion of gas ballast present. The final pressure is increased as a result. Owing to the design, gas ballast does not have any influence on the pumping speed of two-stage .

Lubricated rotary vane vacuum pumps - DVP

The lubrification allows this pumps to intake water vapour. To avoid a condensation of the water vapour, the lubricated rotary vane vacuum pumps are equipped with the gas ballast, a system that introduces air in the compression stage and changes the vapour saturation pressure thus avoiding the condensation.
