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.

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 Ballasting of Vacuum Pumps (Part 2) | 2017-01-10 .

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.

The use of gas ballast in rotary vane vacuum pumps- Vacuum .

The ballast valve can accelerate the extraction of steam without polluting the oil. If the rotary vacuum pump only pumping permanent gas, the gas does not liquefy due to the increase in pressure, so there is no deterioration of the pump oil. However, if the pump is used to vacuum dry or pumping humid air, the gas will have not only permanent gas but also Water vapor, if this portion of water .

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 .

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 .
