what's the shaft size on this permco 257 series pump

Question by: Terry W on Dec 15, 2025, 3:55 PM

The 1 3/4 designation on this unit refers to the shaft size. That measurement is built into the series callout itself, so if your setup is spec'd for a 1 3/4 inch shaft, this is the one you're looking at.
