Got a Motor620 piston pump that needs a new square key, this the right part for that?

Question by: Howard H on Apr 3, 2026, 7:56 AM

For Motor620 configurations using Danfoss Power Solutions piston pump assemblies, yes, that's exactly what this key is built for. It handles the shaft-to-wheel engagement on those setups, and it comes as a single unit per package, so you're getting one square key per order. Width on it is 0.31 inches, which is sized for proper fitment in the supported assemblies.

This square key is designed to fit all configurations and sizes of the Motor620, so it should work as a replacement part in your piston pump setup.
