The importance of gas ballast for vacuum pumps

Sep 27, 2019 · Originally developed in 1935, gas ballast is nevertheless still considered a significant addition to a mechanical oil sealed vacuum pump. When used in this way, the gas ballast helps reduce the amount of vapour condensation (and thus contamination) of the pump's sealing-oil.

Water vapor tolerance / water vapor capacity

Without gas ballast, a vacuum pump having an outlet temperature of less than 100°C would not be capable of displacing even small amounts of pure water vapor. If water vapor is nevertheless pumped without gas ballast, the condensate will dissolve in the pump oil. As a result, the base pressure will rise and the condensate could cause corrosion .

Oil Sealed Rotary Pumps Understanding Gas Ballast

Gas Ballast • By opening the Gas ballast valve on the rotary pump: 1. A small amount of air flows into the compression portion of the pump cycle. 2. This additional air mixes with the gas/vapor being compressed. 3. The gas/vapor mixture is now greatly diluted. There is more % of dry gas than % of vapors. 4. There is now less tendency of .

Gas ballast

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.

The Gas Ballast on a Oil Sealed Rotary Vane Pump .

What is a gas ballast? Vacuum pumps designed for pumping vapours are generally equipped with a 'gas ballast' control. The gas ballast allows a controlled amount of gas, generally air from outside the pump, to be introduced into the pumping mechanism. Typical applications would include rotary evaporation, distillation and gel drying.

Rotary Vane Vacuum Pumps, The Definitive Guide

Opening the gas ballast valve will protect the vacuum pump but it will decrease the performance of the vacuum pump; therefore, there is a trade off. Additionally, a gas ballast valve can be used as a diagnostics tool to help determine contaminated fluid from a leak.

Common mistakes when using a laboratory freeze dryer .

The majority of vacuum pumps have a gas ballast that can be used to purge containments from pump oil. After the freeze dry run, a pump should be allowed to operate with the gas ballast open for 20-30 minutes. This gives any vapors that condensed in the pump an opening in which to leave the pump. Running the pump .
