Product Questions & Answers

part number 3922-103, is that the Eaton S2 series or something different? trying to make sure I'm ordering the right pump before I pull the trigger

Question by: Debbie H on Mar 26, 2026, 9:15 PM

Same pump, different label. The 3922-103 is the Char-Lynn branded version of the Eaton S2 39 cubic inch variable pump. Char-Lynn is a brand that falls under the Danfoss/Eaton family, so you'll see it listed both ways depending on the source. If your existing unit or parts list calls out 3922-103, you're in the right place.

Will this pump work on my older Char-Lynn system, or did they change something over the years?
