Wet Rotor Advantage
The wet rotor design eliminates the need for external shaft seals and separate lubrication, as the circulated fluid itself lubricates and cools the motor. This results in whisper-quiet operation, reduced maintenance requirements, and extended service life — ideal for closed-loop hydronic heating systems, radiant floor heating, and chilled water distribution.
Three-Speed Flexibility
With three selectable speed settings, the UPS 32-80 F allows installers and technicians to fine-tune system flow rates to match specific load requirements, improving energy efficiency and system comfort across varying demand conditions.
