Radiantec uses circulators (pumps) manufactured by Grundfos. They are quiet, reliable, and backed by a good warranty. Grundfos pumps are specifically designed for heating and cooling systems. The wet rotor design ensures quiet maintenance free operation. Our 3-Speed models allow you the ability to adjust the pump speed to fit your specific application. Radiantec has tried other circulators in the past. Because our customers appreciate their reliability and quietness, we always come back to Grundfos.

Be sure to order the Isolation Flange Kit when ordering. This kit allows for easy pump removal. The flange kits are pre-built into our Zone Distribution Manifold.

Closed systems will use cast iron pumps. Potable water systems or systems without oxygen barrier tubing use stainless steel pumps. Call us if you’re unsure about which pump to order.
