Cold trap - Wikipedia

In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases into a liquid or solid. The most common objective is to prevent vapors being evacuated from an experiment from entering a vacuum pump where they would condense and contaminate it. Particularly large cold traps are necessary when removing large amounts of liquid as in freeze drying.

Need a cold trap? - Chemistry Stack Exchange

Ideally you should have pump attached to dry ice/acetone trap followed by a cold water condenser (from the rotovap). There are several reasons to have a cold trap. Protection of the pump is one of them. The other reason is that a pump can maintain deep vacuum OR pump large volume of material, but not both.
