AT Pump Tag Question
I got a used AT SD-309 pump. On the tag it says:
IMPELLER TRIM: 9.5
What does that mean? Does it have a 9.5 inch impeller? What would that correspond to on the Berkeley impeller chart?
Yes, it would have a 9.5 impeller if it hasn't been changed or cut down. Only way to know for sure is to measure it.
Berkeley does NOT have an impeller that would compare to that, so it would not be on the chart. Rough compairison would be a AAAA or bigger impeller.
