You can pump first without the Vacu-vin if you want to to. Then you can add the ring (or the corktop) and use the Vacu-vin to create more suction.
Both ways work. Nowadays I usually might start creating the suction with the Vacu-vin from the start, but surely I could do the initial suction with just the BM or Penomet.
Matter of a preference, I would say.
