Will this key work with a 45VQ series pump?

Question by: Brent B on Dec 17, 2025, 8:32 AM

This square key is listed as a compatible part for the 45VQ series.

Is this the same key that goes on the 45VQ series shaft, or is that a different part number altogether?

Question by: Marvin H on Aug 24, 2025, 12:43 PM

this is the right one. The catalog number C1LB23 corresponds directly to the 45VQ Series shaft key, sold under the Eaton Vickers line. It's a square key, so it fits the square keyway on that shaft. If your machine runs a 45VQ pump and you're replacing a worn or missing shaft key, this is the correct part.
