At Lee Supply we offer a full line of circulator pumps for hydronic heating, potable water recirculation (plumbing), and solar thermal applications from the top brands in the industry. We have product experts that will help you find the right circulator pump for your application and answer any questions you might have.
Pumps for Heating Systems (Closed Systems)
Cast-iron pumps are designed for closed systems. Closed systems are usually associated with hydronic heating and cooling applications like radiant floors and baseboard systems. These are systems into which fresh water is not introduced, and excess oxygen has been removed with some type of air vent, air eliminator or air purger.
Potable Water Circulation (Open Systems)
An open system is connected to your main water supply by way of the water heater. Fresh water is regularly introduced as water is used at fixtures. Pumps used in these systems are made of either bronze or stainless steel - materials that will not rust. A dedicated return line to the water heater, or the home's existing cold water line, can be used to return cooled water for reheating.
Parts & Accessories
In addition to offering circulator pumps for open and closed heating systems, we also provide all of the parts and accessories that are needed including: pressure reducing valves, pump motors, air vents, flanges, couplers, gasket sets, and many others.
