Grundfos 00519603 Flange Set

Grundfos 00519603 Flange Set

The Grundfos 00519603 Flange Set is a critical hardware component for securing 1.25" NPT connections in high-demand hydronic systems. Engineered specifically for compatibility with Grundfos UP Series, UPS Series, and TP Series circulators, this cast iron flange set provides the structural integrity required for both residential and light commercial heating applications. As a veteran technician knows, the precision of the fit between the pump and the piping is what prevents nuisance leaks and cavitation-inducing air ingress.

This GF 15/26 flange kit includes two heavy-duty flanges, two high-temp gaskets, and four robust nuts and bolts, ensuring you have the complete assembly ready for the truck. The threaded connection design allows for a seamless transition to 1-1/4 inch NPT piping, maintaining hydraulic efficiency across the CI series circulator interface. Built to withstand the thermal stresses of hydronic loops, these replacement pump flanges are the standard choice for contractors prioritizing a reliable, non-corrosive seal in closed-loop systems.

Key Benefits
  • Universal Compatibility: Integrated design works with the Grundfos UP, UPS, and TP series (model GF 15/26) for wide-ranging field utility.
  • Heavy-Duty Construction: Rugged cast iron material provides superior pressure resistance and longevity in hydronic environments.
  • Complete Install Kit: Includes 1.25" NPT flanges, gaskets, and mounting hardware for a standard 2-bolt installation.
  • Precision Seal: Tight tolerances ensure a leak-free pump flange connection, reducing maintenance call-backs.
Common Questions

Does this set include the gaskets and mounting bolts?
Yes, the Grundfos 519603 is a full kit containing two flanges, two gaskets, and the four necessary bolts and nuts for a complete circulator pump installation.

What is the center-to-center bolt hole dimension?
This 1-1/4 inch flange set features standard 3-5/32" center-to-center bolt hole spacing, matching the standard dimensions of the Grundfos UPS/TP housing.

Is this flange set suitable for potable water systems?
This specific cast iron pump flange is intended for closed-loop hydronic heating and cooling. For domestic potable water, a bronze or stainless steel alternative is required to meet code.
