Grundfos Cast Iron Flange Set

The Grundfos Cast Iron Flange Set gives you a threaded, serviceable connection between a Grundfos circulator pump and the system piping. Use it to install a new circulator or replace worn pump flanges. Each set has cast iron pump flanges with matching gaskets and mounting hardware.

Key Features:

• Cast iron flanges for durable, long-lasting service in hydronic heating and circulation systems
• Threaded NPT pipe connections for a secure fit to the system piping
• Gaskets help create a leak-resistant seal at the pump connection
• Bolts and nuts included for mounting the flanges to the pump
• Removable connection that makes pump service and replacement easier

Made by Grundfos, a well-known name in circulator pumps, these flange sets are an OEM-style accessory for compatible Grundfos circulators. They come in several connection sizes, so choose the one that matches your pump and piping.
