Rotary vane vacuum pump air ballast valve. Means through which air or another non-condensing gas is admitted into a vacuum pump are referred to as gas ballast.If the pump is displacing vapor that would condense in the pump at the corresponding temperatures without gas ballast, the gas ballast enables the outlet valve to open before the vapor condenses, and the vapor is discharged together with the ballast gas. The SOGEVAC SV300 B are single- stage, oil-sealed rotary vane pumps. Means through which air or another non-condensing gas is admitted into a vacuum pump are referred to as gas ballast.If the pump is displacing vapor that would condense in the pump at the corresponding temperatures without gas ballast, the gas ballast enables the outlet valve to open before the vapor condenses, and the vapor is discharged together with the ballast gas.

A0086. In simple terms, a gas ballast valve incorporated into the system will allow a small portion of the compressed gas (containing this detrimental condensate) to be expelled without impacting … Once the air is drawn in and mixes with the pumped gas, the water vapor being carried in the pumped gas makes up a smaller percentage of the gas, which now includes the ballast gas (air) as well. Actually, gas ballasting is a very simple operation and when properly applied can keep vacuum pumps in optimal conditions even when used in wet processes that can potentially contaminate the oil with condensation. Weight. The rotor mounted eccentrically in the pump cylinder has three vanes which Gas ballast should generally be run all the time that vapour is being passed through the vacuum pump. SKU.
