Circulators or pumps are an integral part of any hydronic heating system. We also carry the flanges that are needed to install them.
A circulator (pump) is the center of the hydronic system. Pumps are used to move water through the system. They can also be used for zoning purposes. There are many important factors to consider when purchasing a pump such as application, GPM, head range, material, voltage, and horsepower. Proper sizing of the pump is very important for any hydronic project. If you need help choosing the right pump for your application, contact us and we will be glad to help.
By far the most popular pumps are 3 speed pumps. 3 speed pumps can be used in a variety of applications and speeds, reducing the amount of pumps you need to carry.
Variable speed pumps vary their speed as the heating load of a hydronic system changes throughout the day. The heating load of a system is dependent on factors such as outdoor temperature, solar gains and demand. 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.
We offer a wide selection of Grundfos and Taco pumps and flanges. If you don’t see something you are looking for contact us and we will find it for you.
