Grundfos UPS 25-80 Cast Iron Three Speed Circulator Pump for Hydronic Heating with Composite Impeller

Peace of Mind
Product Overview
Larger homes with extended radiator networks or multiple heating zones place more resistance on the circulating pump than a single small loop, requiring additional head to maintain consistent flow. The Grundfos UPS 25-80 is sized to meet that requirement, with cast iron construction suited to closed-loop heating systems.
The pump delivers approx. 132 L/Min at its highest speed setting with a maximum head up to 8 m of maximum head, with power stepping from 114 W to 160 W across its three selectable speeds and current reaching 0.7 A on a 1 x 240 V supply. That head rating gives it enough reserve to overcome the pressure drop across a larger radiator count or a longer branch circuit.
A canned rotor motor removes the mechanical shaft seal, with the rotor and bearings lubricated by the heating water itself. Liquid temperature tolerance extends from -25°C to 110°C, which allows for plant rooms exposed to cold conditions before the heating season begins.
The enclosure steps up to IPX2D for improved contact protection compared with the smaller UPS 25-60 models, and internal thermal protection is built into the motor winding itself. At 180 mm port-to-port with 1 1/2 inch connections, it fits standard domestic heating pipe centres.
FEATURES
- Higher head rating of up to 8 m provides additional pressure capability for extended radiator networks and multiple heating zones
- Three-speed selector permits field adjustment from 114 W to 160 W
- Canned rotor design removes the mechanical shaft seal as a potential leak path in heating applications
- Internal thermal motor protection safeguards the winding against overload in continuous seasonal operation
- Cast iron housing specified for closed-loop heating applications where potable water approval is not required
- Liquid temperature tolerance from -25°C to 110°C accommodates plant rooms exposed to cold conditions
- IPX2D enclosure rating provides protection against dripping water and contact in service environments
- 180 mm port-to-port body dimension aligns with standard domestic heating pipe centres
