I've been playing with the RPM of my Intelliflo with the spreadsheet that Mark's produced and cross referenced with Pentair's chart. I found some anomalies; would they make sense? Note that I'm putting ranges, as I see the watts very over time.
RPM Watt GPM (Mark's chart) TDH (Penair's chart)
1100 145-155 19-25 10/9
1400 185 11
1500 228 17 19
1600 286 26
1800 409 37
2350 845 52 40
2400 891 53
Questions:
- Does it make sense that 1100 RPM has 2x the flow than that at 1400?
- There are huge jumps in power between 1600 & 1800 RPM (1.5x) and 1800 and 2350 (2x). Is that due to the head increase with flow increase?
