I’ve been tempted to throw in a pump regimen into my newbie routine but with the intent to keep it light. I have used pumps before and I figure as long as I keep it on a safe low pressure and not go crazy I should be fine. The only reason I haven’t is that I don’t have the doh to dish out on a quality one (because from what I read, its pointless to get the adult toystore quality).
I don’t think it hurts to throw it in your routine, but remember to never get carried away in both your frequency and your pressures (its easy to get excited when your penis gets larger than normal). I would venture to guess twice a week at light-to-moderate use is sufficient. This will allow you to know whether you like pumping, and to let you get into more advanced pump work when you start to modify your newbie routine in a few months.
I will mention that you want to read up on the pros and cons of pumping, because like with any other device-required PE, it has its risks.
