A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit.

Frequently Asked Questions

A circulator pump is responsible for circulating water or other fluids through the pipes in hydronic heating and cooling systems. It ensures continuous flow to maintain temperature and efficiency in the system.

We offer a variety of circulator pumps, including in-line pumps, wet-rotor pumps, and standard circulators, designed for both residential and commercial HVAC systems.

The right circulator pump depends on your system’s size, flow rate, and head pressure requirements. It’s important to check the product specifications or consult with our team for assistance in selecting the right model.

Yes, you can replace an old circulator pump, but ensure compatibility with your system’s specifications. Be sure to check the capacity, voltage, and pump type before replacing.

Installation involves connecting the pump to the system’s piping and ensuring proper alignment for smooth water flow. For best results, follow the manufacturer's instructions or consult a professional HVAC technician.
