Pumps & Flanges
Pumps or circulator pumps are an integral part of any Hydronic system. The pumps are used to send water to an area of the hydronic system when it is called for, or to keep the flow of water in the system. For proper installation the pumps should be purchased with a pair of flanges to connect to the water line. Taco Pumps are the best selling pumps on PexSupply.com. These pumps include the Taco Cast Iron Pumps, the Taco Cast Iron IFC Pumps, and the Taco Bronze Pumps. Taco Pumps are ideal for radiant heat systems. The may be used in the primary loop, or for zoning purposes they may be used along with a switching relay and thermostats. The best selling Taco pump is the Taco 007 Cast Iron Circulator Pump.

More About Pumps & Flanges
A pump (circulator) is the heart of a hydronic system. Pumps move water through the system at a desired rate. They may be utilized in a primary loop or for zoning purposes. Pumps require a flange to connect to a supply line. There are many important factors to consider when purchasing a pump such as application, GPM, head range, material, voltage, and horsepower.
GPM (gallons per minute) is a measure that indicates the maximum flow rate of water a pump can circulate at a given head range. Head range is the number of feet a pump can raise or lower a column of water at atmospheric pressure.
Pumps that are solely used for closed loop hydronic systems can be constructed of cast iron. Closed loop systems contain water that is de-oxygenated which prevents the cast iron pump from rusting. However, in open loop systems a steady flow of oxygenated potable water is present. These systems require either bronze or stainless steel pumps to prevent the pump from corroding over time.
Variable speed pumps vary their speed as the heating load of a building changes throughout the day. The heating load of a building is dependent on factors such as outdoor temperature and thermostat setting. Variable speed pumps are best for zone valve systems with a one system circulator. They are also ideal in radiant heat systems that use manifold actuators with multiple zones on a single manifold.
Pumps can be equipped with an internal flow check valve (IFC). IFC pumps eliminate the need for a separate in-line flow check in the hydronic system.
