Large heating networks combine both high resistance and high volume, requiring a pump that can deliver both. The Grundfos UPS 32-100 meets that demand by pairing the widest bore in the cast iron UPS range with its tallest head rating, suited to commercial risers, district-style heating loops, and extensive multi-zone residential systems.
At full speed the pump delivers 113.8 L/Min against a maximum head of 10 m, with three speed settings stepping power from 280 W to 345 W and current reaching 1.52 A on a 1 x 240 V supply. The 2 inch connection reduces flow velocity and associated resistance compared with the narrower-bore UPS 25-100 at equivalent volumes.
Canned rotor construction runs through the model, with bearings lubricated by the circulating heating water rather than a mechanical seal. Liquid temperature tolerance extends from -25°C to 110°C, and the cast iron housing is intended for closed-loop heating rather than potable circuits.
Class H insulation and an IPX4D enclosure reflect the higher thermal and ingress protection demands of running at 345 W continuously. At 180 mm port-to-port, the pump matches the physical footprint of the 1 1/2 inch UPS 25-100, allowing bore size to be increased during a system upgrade without altering pump spacing.
FEATURES
