Most circulator pumps connect to a system’s piping with flanges (union and threaded options exist for some models). Standard pumps use standard-sized flanges. The pipe size of the flanges must be selected based on the piping to which they will be attached.
Generally, flanges run parallel to the pump’s casing. In certain instances, this may create spacing issues in the boiler room. The solution is a vertical flange pump. Also known as rotated or inverted flange, these pumps have flange connections that run perpendicular to the motor casing. The flanges that bolt on vertical flange pumps are the same; they just face in a different direction because of the configuration of the pump. One popular vertical flange pump is the Taco 0015-MSF2-1IFC. SupplyHouse.com stocks a wide range of circulator pumps from Taco, Bell & Gossett, Grundfos, and Wilo.
