There is really no limit to how far the equipment can be from the pool but there are consequences. The longer the runs, the more head loss there is in the plumbing and the less efficient the pump will be. You can compensate some by using larger pipes and/or multiple runs. For that length, I would use at least 2.5" pipe and have separate runs for each suction port (e.g. skimmer, main drain pair, cleaner, etc).
