If you go high volume you must have a 9 quart pan or you will suck it dry. Mellon high volume pump M83HV has a max flowrate of 8 Gallong Per Minute at 6K rpm and 4 gallons per minute at 2000 rpm's. The mellon tech actually indicated it flowrate peaks at about 4K rpms and stays flat until 6k rpm. I assume because the net positive suction heads availabe limits flowrate.
