You can use a rotovap without a vacuum pump but for this to work you need to leave it open, otherwise possible overpressure from your DCM vapors will do this for you by shooting the stop cock out of the joint. Having little bit of underpressure even for solvents like diethyl ether and DCM is the way to do it, so you definitely want to have a pump.
