vacuum pump as the root cause of the problem. However, the vacuum pump usually isn't culprit. In almost all cases, either: 1) the pump is being operated in a condition for which it never was intended, 2) one or more of the user's interface points with the pump (suction/discharge lines, water supply, process contaminant, etc.) are be-

Oil Mist Vacuum Pump Discharge Eliminators Maintenance .

Rule of Thumb #2: Determine the type of oil being used in the vacuum pump. Trade names, viscosity/grade of oil, and the lubricant base (mineral, synthetic, etc.) are all useful in determining the discharge aerosol characteristics. Rule of Thumb #3: Determine how much oil the pump consumes under normal operating conditions.

On oil in the GD4 pump: The GD4 pump has a special valve to prevent any backflow of oil into the instrument, so that is not an issue. Some people still want "no oil in the room", which is a bit OCD, considering how well ventilated modern preparation rooms are, but would perhaps be a concern if the pump did generate a significant amount of oil.

Fundamentals of Vacuum | Hydraulics & Pneumatics

During pump-down, the higher a vacuum becomes, the fewer air molecules remain in the closed volume. Therefore, fewer molecules can be removed by each pump stroke. As a result, there is a logarithmic relationship when approaching a perfect vacuum. The time required to pump a system down to a certain vacuum level can be approximated using this .
