My March pump puts out 951 GPH @50 hz. True, this is less than Calpeda. I loosely used Bill Rouse's formula of 1 GPM for every 4,000 BTU which says I need min 405 GPH. I have more than double using that metric. In any event all works well for over a year. The pump I replaced was a March LC-5C-MD (original Calpeda failed ten years ago) which had a slightly lower capacity than current unit: 54.8 LPM vs. 60 LPM. It lasted nearly nine years. Two of three AC's are original and run well. Aft unit was replaced with Marine Air 10K unit as previous owner wanted to be frozen.
