Pump Flanges

Isolation flanges for connecting circulator pumps. The collection includes Webstone lead free rotating isolation flanges in 3/4" FIP and 1" sweat, 1" sweat flanges with a hose drain, and a 1" press flange with hose drain for high velocity pumps.

Isolation flanges let a circulator be removed without draining the system, and the rotating design helps line up bolt holes. Match the pipe connection, FIP, sweat or press, and the flange pattern to the pump. A hose drain allows purging and draining at the pump. Check the pump manufacturer for flange size.
