Question by: Gary R on Jul 5, 2025, 4:28 PM

Got a piece of equipment that calls out a C1DK48 and trying to figure out if this Permco unit is the same thing. Am I looking at the right pump here?

C1DK48 is listed as an alternate part number for this pump, so yes, you're looking at the right unit. That cross-reference is specifically noted to help with sourcing compatible replacements, and the RZ-0577-22 is the SKU tied to it on this end.

What size is this Permco pump? I'm needing one that's about the same size as what I already got.
