The gas ballast facility (see Fig. 2.13) prevents condensation of vapors in the pump chaer of the pump. When pumping vapors, these may only be compressed up to their saturation vapor pressure at the temperature of the pump. If pumping water vapor, for example, at a pump temperature of 158°F (70°C), the vapor may only be compressed to 312 ar (saturation …
4.1.6 Gas ballast. 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 …

Jul 07, 2020· The pump has a ballast valve. I have read that on the premier pump the ballast helps keep water out of the oil, I assume that the function of the standard pump is the same, hence the ballast will do the same thing. However I have found videos online that says to always leave the ballast closed on the standard pump. What is HR’s take on this?
Nov 26, 2016· 11159. Dislikes (Given) 22. Dislikes (Received) 60. Regarding your question about harming your vacuum pump with the gas ballast open, the answer is no. It is designed to do that. It does create a ''false'' load on the pump which keeps the vacuum pump oil hotter to better drive out any moisture from collecting there.

In this article we will only discuss one and two-stage “medium vacuum” oil sealed rotary vane vacuum pumps that can produce a alog ultimate vacuum of about 1 x 10-2 Torr (0.01 Torr or 10 microns) for a one stage model and about 1 x 10-3 Torr (0.001 Torr or 1 micron) for a two-stage model. We will
Use gas ballast when working with condensable vapors. A vacuum pump’s gas ballast pushes condensates through the pump and out the outlet, purging some of them from the oil. A hybrid pump (rotary vane/diaphragm pump) will keep the oil reservoir under a vacuum for appliions with heavy vapor loads and corrosive gases.
