Vacuum pump high vacuum system

Many users often question whether their high vacuum system needs a bypass line. To understand whether the system requires a bypass line, we must first understand the role of the bypass line.

Whether the bypass line is used depends on the pumping time of the vacuum system. If the pump cavity is smaller, the overall extraction time is shorter, generally do not recommend to add bypass piping, pipe valves not only after all the extra increase procurement costs and increase the leakage rate and the maintenance of the system components.

If the cavity is large, the front stage vacuum pump is large or large, and it needs to be pumped for a long time. It is recommended to equip the front suction system with bypass line. Due to the high pumping efficiency, some leakage does not have a big effect on the final vacuum. And long running, can help the user to save power.
