What do you mean by(unfortunetly right now we cannot find any solution for this because of some administation problems)
Is this a draw tray for the LVGO or HVGO? Are you running your draw tray dry when you say "operator can not see the level in the column"?
It's going to help a lot if you can provide a sketch and some details of the system and the problem.

I suggest that you break your response into sentences.
Who originally specified these pumps ? Are datasheets available ?
Are there pump NPSHa calculations or even pump curves available to you ?
Or did an MBA tell you that the unit purchased from another company and all records, operating manuals, pump curves etc were discarded by the previous owner ?

Is it because the wrong selection of the pump?
If so is there any solution to find the right pump?
Sorry for the late replay.

Vacuum columns can be difficult, you are often trying to move boiling point liquid. As RaRo points out, increasing your liquid head above the pump is an excellent way to overcome some of the problems.
