Usage

The Grundfos UPS 43-44FC is designed to circulate water in closed-loop hydronic heating and cooling systems. Typical applications include commercial boilers, radiant floor heating, fan coil units, geothermal systems, solar heating systems, and chilled water loops. The integrated 3-speed selector allows installers to optimize flow and head to meet system requirements, while the built-in integral check valve helps prevent reverse flow. Because it features a cast iron housing, this pump is intended for closed-loop HVAC applications and should not be used in potable domestic hot water systems.
