Usage

The UPS 26-150 F is designed to circulate water in closed-loop hydronic heating and cooling systems. It is commonly installed in commercial boilers, radiant heating systems, chilled water loops, geothermal systems, district heating networks, fan coil systems, and primary/secondary pumping applications. The integrated 3-speed selector allows installers to match pump performance to the system's required flow and head, improving efficiency while maintaining reliable circulation. Because this model has a cast iron housing, it is intended for closed-loop HVAC applications and should not be used for potable domestic hot water systems.
