Rotary Vane Vacuum Pump - Principles of Operation | Dekker .

Features of the DEKKER Vacuum rotary vane pumps include: an automotive spin-on oil filter (on larger sizes) a built-in inlet anti-suckback valve that prevents the pump from rotating backwards when shut down with vacuum remaining in the process and prevents the rotor housing from flooding with oil; a built-in gas ballast valve

Duravane Rotary Vane Vacuum Pump Systems - Principles of .

The main function of the gas ballast valve is to prevent water vapor from condensing in the pump which can cause emulsification of the lubricating oil, resulting in possible pump seizure. If the vacuum pump does not reach the rated ultimate vacuum, it may be because the oil is contaminated with process vapors or water. To clean out the pump .

8 Rules for Diaphragm Vacuum Pump Success - VACUUBRAND

Rule 8. Clean the pump before storage. Run the pump for a few minutes with the gas ballast valve open after your operation to blow any residual vapors through the pump before storage. This purges vapors that, if left untouched, could condense in the pump when it cools after shutdown and cause corrosion during storage.

DO NOT START PUMP BEFORE ADDING OIL OPERATION The following procedures will prevent oil from being drawn into the pump cartridge and creating hard start-up. START-UP: Open one intake port and isolation valve, close gas ballast valve and start pump. Make vacuum connections. Crack gas ballast valve for the first part of the evacuation procedure.

Oil Sealed Rotary Vane Pumps - Vacuum Furnace Engineering .

Mar 05, 2019 · The ballast gas is injected through a one-way (aka "gas ballast") valve, located at the top of the pump (Fig. 10). One way to think of the use of a gas ballast is that opening the gas ballast valve deliberately destroys the efficiency of the pump, which in turn causes the pump oil to heat up and drive moisture and other volatile vapors out .

VACUUM PUMP OPERATING INSTRUCTIONS

3. GAS BALLAST VALVE (2 STAGE MODELS) The gas ballast valve must be partially opened for the first part of the evacuation procedure. After about two minutes close the valve and continue the evacuation procedure to reach ultimate vacuum. Failure to close the valve during high vacuum operation will result in poor vacuum performance.
