Rotary vane pumps are subjected to severe stress by certain process gases and operating modes. Optimal protection for the pump can be provided by using auxiliary gases. The combination of gas ballast and flushing gas in this form is available only from Pfeiffer Vacuum.
Gas ballast is used primarily in drying, freeze-drying and distillation applications. Flushing gas is the preferred choice for severe loading cases, corrosive applications and all processes that use aggressive media.
If corrosion is prevented, the pump has a longer service life. Longer intervals between oil changes also result in a reduction in costs.
