Flanges will attach to your pipe through the threads by simply screwing them into place. Flanges have female thread, so you will need a pipe with male thread or a male connector on the end of your pipe. Any brand flanges will fit any brand pump, so you can use Grundfos flanges on a Grundfos pump such as the UPS15-58FC, or on a Taco pump. Flanges come in pairs, so when you purchase one set, you get flanges for both sides of your pump.
The Grundfos UPS15-58FC pump (part number 59896341) and other Grundfos pumps and Taco pumps can be found at www.supplyhouse.com
