Great skimmer. I know Roger mentioned dc pump but for skimmers like pm I would opt for a pump based on head pressure and not just gph. Personally and from experience I would use pan world 55hd or a reef flow sword tail. Not sure if any of the dc pumps other than abyzz or royal exclusive that can handle pressure required for that skimmer to perform at its best.
A ecotech l1 might work as well
