IDP-7 dry scroll pump startup procedure

Hello, I'm working with a new IDP-7 dry scroll pump and need to start it up tomorrow morning. The IDP-7 instruction manual states that to place the pump into use and ensure it achieves maximum vacuum that I should seal the inlet port and operate the pump for 24 h in this manner. We have the appropriate NW caps but the practice in our lab is not to run equipment overnight. Can anyone elaborate on a suitable alternative for breaking in this IDP-7 to ensure good results? Strictly speaking I also need to place this pump into operation tomorrow because my current scroll pump overheated on Saturday and I need to place the chamber this pump is connected to under vacuum tomorrow.7

  • Hi Rick,

    The manual states to run the pump 24 hours with the inlet blanked off in order to ensure the pump can reach the maximum rated pressure that it's designed for; <20 mTorr. This is to help pump away condensed water vapor from within the pump.

    An alternative: you can open gas ballast 1 for a few hours, remove the plug and insert the sintered plug, or remove the removable insert from the plug. By letting a little gas in through the gas ballast you help to sweep out or purge the pump from condensed water. For further details on gas ballast, please refer to the 2 minute tutorial:

    Before doing this, do you need the pump to be able to reach maximum specified pressure (<20 mTorr) tomorrow? What pressure do you need to operate at tomorrow? You may just be able to hook it up and run it.
