Product Overview
The Grundfos UPS 50-120 F 415V circulator pump combines high head generation with substantial flow rates for commercial heating networks and central air conditioning systems. It circulates thermal fluids through high-resistance boiler primary circuits and extensive fan coil distribution headers.
An EN-GJL-250 cast iron casing with a 280 mm face-to-face length houses a pressed AISI 304 stainless steel impeller, stainless rotor can, and bearing plate. The unit handles maximum working pressures of 10 bar (PN 6/10) and liquid operating temperatures from -10°C to 120°C, weighing 23.1 kg.
The 3-phase 400-415 V 50 Hz motor has a maximum power input (P1) of 720 W at 1.3 A at top speed, offering three selectable speed curves for system commissioning. Hydraulic performance produces a maximum head of 12 m and a calculated flow rate of 16.3 m³/h (272 L/Min) via DN 50 DIN flanged pipe connections.
Ceramic radial bearings and a carbon axial bearing operate fully immersed in the circulating fluid, preventing seal wear and shaft leakage. The IPX4D motor casing includes Class H insulation and internal thermal switches for interconnection with motor control centres.
