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 .
