Product Overview
Underfloor heating circuits and multi-zone hot water systems place more resistance on a pump than a simple recirculation loop, requiring additional head to maintain flow across extended pipe runs and manifold assemblies. The Grundfos UPS 25-80N is designed to meet that requirement, with an 8 m maximum head rating that keeps flow consistent across larger circuits.
On its highest speed setting the pump moves 82.5 L/Min against a maximum head of 8 m, with power scaling from 114 W up to 160 W across its three settings and current reaching 0.7 A at 1 x 240 V. That range allows the same unit to serve a smaller zone at reduced speed or a full underfloor loop at full output.
Construction follows the canned rotor principle used across the UPS N range, with the rotor and bearings lubricated directly by the system water rather than a separate mechanical seal. The stainless steel housing and composite impeller extend the pump's liquid temperature tolerance down to -25°C, useful in plant rooms exposed to cold conditions before start-up.
Internal thermal protection is built into the motor itself, and the enclosure carries an IPX2D rating for contact protection. At 180 mm port-to-port with 1 1/2 inch connections, it shares mounting dimensions with the smaller UPS 25-60N, simplifying upgrades where more head is later needed.
FEATURES
- Three-speed selector provides field adjustment to match pump output to the hydraulic resistance of underfloor manifolds and multi-zone configurations
- Canned rotor design integrates the pump and motor without a mechanical shaft seal
- Internal thermal motor protection safeguards the winding against overload in continuous heating service
- Stainless steel housing with potable water approval and wide temperature tolerance from -25°C to 110°C
- Composite impeller construction offers consistent hydraulic performance in heating and hot water applications
- IPX2D enclosure rating provides protection against dripping water and contact in service environments
- Canned rotor design with self-lubricating bearings supports continuous operation without routine intervention
- 180 mm port-to-port body dimension matches the mounting footprint of the smaller UPS 25-60N
