Wunf 400 Upd

2. Dual-Circulation Industrial Pumps (Grundfos UPD 400V Series)

Operating at a native 400V architecture significantly improves electrical efficiency compared to standard single-phase 230V options. The 3-phase configuration delivers higher starting torque, lower running currents, and reduced heat buildup inside the stator coils. Multi-speed manual switches or external frequency converters (VFDs) let building managers precisely scale power usage to meet real-time thermal demand.
