back plate for a danfoss piston pump - this the right part for that?

Answer by: Customer Support on May 31, 2025, 8:40 AM

the 70553-303 is a back plate assembly made specifically for Danfoss / Eaton piston pumps. It falls under the piston pump accessories category, so if you're working on one of those units and need a back plate, this is the correct part. Eaton Char-Lynn manufactured it, and it's now carried under the Danfoss Power Solutions brand, so you may see either name depending on where you're sourcing from.
