Common Questions

What flange sizes can I use with the E24.2?
This pump is compatible with 1", 1-1/4", and 1-1/2" 2-bolt flanges, though flanges must be purchased separately.

Is this pump suitable for potable water systems?
No, this specific cast iron model is designed for closed-loop hydronic heating and cooling. For potable water, a bronze-body version is typically required.

Can I install this pump in a vertical or horizontal orientation?
The Model E24.2 is an in-line circulator; however, it should be installed with the motor shaft in a horizontal position to ensure proper bearing longevity.
