You can leave your pump running as long as you think is needed, check now and then if the pump is not getting to hot and check oil level...
normally if you have a good sealed bag you can shut down the pump once the resin has fully saturated the CF or FG or whatever laminate you've put 
in the mould.

Before you shut down the pump clamp down both lines (infusion side and vacuum side)
Now you could just leave it like that and let it cure overnight...but you bug has to be fully closed without leaks.
If you have some leaks you could continue using the bag and mould but with risk or pinholes, airbubbles, places without resin.
Just put the pump on now and then



Hope this answers your questions?

Hi

Many thanks for the reply, is it worth placing a T piece in the vac side and fitting a gauge to monitor the vacuum ?

Hi Chris
It is my understanding that a oil bath vacuum pump must not be left on for long periods of time because they get way to hot. What those that want a pump to run 24 7 get, is a air vane pump. These air vane pumps only get to about 24 HG of vacuum where as the oil bath vane pump like yours will go to full 29.9 Hg vacuum. I hardly ever use my air vane pump anymore now that I get fully sealed bags every time now. I do the half hr drop test, infuse , seal off the lines, shut off the pump, and then cut the tubes off. I then go on to the next part and do the same. Some times I do 5 parts and put them in my oven. I have to admit it was scarey to shut the pump off and cut the lines at first, but now its routine.
Hope this helps.
