Feb 27, 2019 · The correct use of gas ballast valves on rotary mechanical oil seal vacuum pumps has long been regarded as a "black science" or simply a guess. It is a very simple device that, if used properly .
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 .

A rotary vane vacuum pump can remove the dry gas from the sealed container. It can remove a certain amount of condensable gas if it has gas ballast device. However, it is not appropriate to remove some gases that are highly oxygenated, corrosive to metals, react chemically to pump .
The MS120 Single Stage Rotary Vane Pumps are single-stage, rotary vane pumps oil sealed, driven by an electric motor controlled by an inverter. These high vacuum pumps are suitable for pumping air and small quantity of water vapour only. Pumping of other types of gas or vapours must be declared in advance to Agilent Technologies that will give the conformity to the specific use.
May 01, 2017 · To pump condensable vapors. Use gas-ballast (open the gas-ballast control) when there is a high proportion of condensable vapors: Close the vacuum system isolation-valve. Turn the gas-ballast control counterclockwise to fully open. Run the pump for 30 minutes to warm the oil. Warm oil will help prevent vapor condensation in the pump.
Jan 10, 2017 · In addition to rotary-vane pumps, it is also used in scroll pumps and piston pumps, to name a few. Wolfgang Gaede developed the gas ballast principle in 1935, which was first applied to rotary-vane pumps. The ballast gas is drawn into the pump chamber through a one-way valve (aka gas ballast valve) located on the pump.

Mar 05, 2019 · Oil sealed rotary vane pumps (aka rotary vane pumps) are the primary pumps on most vacuum systems used in the heat treatment industry. They are also referred to as a "backing" pump when used in combination with a booster pump, or with both a booster and secondary ("high vacuum") pump, typically a diffusion style. A rotary vane pump can also be used alone when high vacuum is .
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 together with the ballast gas.
Rotary Vane Pump. Table of contents 2 . Safety instructions The safety instructions in Pfeiffer Vacuum operating instructions are the result of risk evaluations and hazard analyses and are oriented on international certification stan-dards as specified by UL, CSA, ANSI Z .
May 01, 2017 · To pump condensable vapors. Use gas-ballast (open the gas-ballast control) when there is a high proportion of condensable vapors: Close the vacuum system isolation-valve. Turn the gas-ballast control counterclockwise to fully open. Run the pump for 30 minutes to warm the oil. Warm oil will help prevent vapor condensation in the pump.
A gas ballast is a passageway that leads into the compression side of the crescent cavity allowing for small airflow. The amount of airflow allowed is controlled through a cap located on the exterior of the pump. Fig.3: Gas Ballast Diagram Using a Gas Ballast. Some pumps have three positions for the gas ballast: closed, medium flow, and high flow.
