How can I make my vacuum pump run longer?
If your toilet doesn’t have enough suction, then adjust this thumb screw to make the vacuum pump stay on longer. But in your case, if your pump is staying on too long and you don’t need that much suction, then adjust it the other way. Flush your toilet, time the pump, then fine tune adjust as necessary.
What happens if you leave the vacuum pump ballast open?
In normal operation of a vacuum pump the gas ballast remains closed. In cases where it needs to be opened the operator should be careful about closing the ballast as soon as possible. Leaving a gas ballast open will cause a vacuum pump to run hotter than normal and causes the vacuum pump oil to break down or “burn”.
What happens when you run a vacuum pump on a leak?
You should contact an expert to inspect the pump thoroughly because if this problem persists, it can damage the unit altogether. Running a vacuum pump on a leak for an extended period of time will make the pump run hotter, and the increase in oil mist production will cause a dip in the oil level of the pump.
How long does a vacuum pump head run?
Both heads flow to a common tank, so logically the forward head will run longer due to the longer run. 25 seconds seems long, but if the system is working correctly I would not fix it. If the time increases then I would start checking further.

How often should I change my vacuum pump oil?
Maintaining your vacuum pump may be as simple as frequent oil changes. The frequency of oil changes is dependent on your application and freeze dryer performance. Interestingly we have customers that change their vacuum pump oil once a year and others who have to change their vacuum pump oil after every run.
What do you need to know about a vacuum pump?
Most vacuum pumps are equipped with a site glass. You should verify in the pump instruction manual that the site glass is connected to the main oil charge and that it is a true indication of the quality of oil in the pump. As a rule of thumb the more highly refined the oil the more contaminants it can tolerate before having to be replaced.
