Grundfos UPS 25-120 Cast Iron Three Speed Circulator Pump for Space Heating with Composite Impeller

Peace of Mind
Product Overview
Multi-storey risers and systems with unusually long branch runs require more head than any other pump in the UPS cast iron range can generate. The Grundfos UPS 25-120 sits at the top of that lineup, purpose-built for closed-loop circuits where vertical lift or extended pipe resistance would otherwise limit circulation to the highest points of the system.
At full speed the pump delivers 34 L/Min against a maximum head of 12 m, the tallest rating among the UPS 25 models, powered by up to 230 W and 0.99 A on a 1 x 240 V supply. Three selectable speeds step power from 125 W upward, allowing the pump to be run below maximum on shorter branches while retaining full head capacity where the riser demands it.
The canned rotor motor lubricates its own bearings using the circulating heating water, a design carried through the entire UPS range that removes the mechanical shaft seal. Liquid temperature tolerance runs from -25°C up to 95°C, slightly lower than the 110°C rating of other UPS 25 variants, reflecting its focus on standard heating rather than higher-temperature boiler applications.
An IPX2D enclosure provides contact protection, and internal thermal protection is built into the motor winding. At 180 mm port-to-port with 1 1/2 inch connections, it retains the same physical footprint as the other 180 mm UPS 25 models, making it a direct upgrade path where an existing installation needs more head without a larger bore.
FEATURES
- Tallest head rating in the UPS 25 range at 12 m for multi-storey risers and systems with unusually long branch runs

What peak liquid flow rate in liters per minute does this high head circulator output through its plumbing threads?
Discharging heating liquid through 180 mm port-to-port 1 1/2 inch connections, the UPS 25-120 sustains a maximum circulating flow rate of approximately 34 L/Min.
What rugged cast iron metallurgy and composite impeller construction are utilized in this circulator?
High-head circulating duty on the Grundfos UPS 25-120 relies on dense Cast Iron casing construction to manage line stresses.
What electrical supply voltage and motor power in kilowatt rating operate this high head circulator?
Operating on facility electrical networks, the UPS-25-120 incorporates a high-head drive rated at 0.23 kW (230 W) across 240 V drawing a rated current of 0.99 Amps.
What operating pressure in bar and liquid temperature threshold apply to this high head heating pump?
High-head closed system limits establish that the Grundfos UPS 25 120 sustains working pressures up to 1.2 bar across temperatures from '-25°C to 95°C.
How much dynamic head elevation can this extended head heating circulator achieve?
Elevating heating fluid across extended pipe networks, the UPS_25_120 reaches a maximum dynamic head of approximately 12 m.
