Grundfos Magna Variable-Speed Wet Rotor Circulators Are Used For Multi-Family Housing, Schools, Hospitals Or Other Commercial or Industrial Applications.
Grundfos Magna Variable-Speed Wet Rotor Circulators are made of solid Cast Iron construction for long lasting durability and dependability. Used for systems with constant or varying flows where it is desirable to optimize the pump duty point, for systems with varying flow-pipe temperatures or for systems where night setback is required. AUTOADAPT™ controls pump performance automatically within defined performance range. Integrated differential pressure control (proportional and constant pressure control). Low noise. High starting torque. Motor based on permanent-magnet/compact-stator technology. Integrated differential pressure control and frequency convertor. Self-venting pump housing. 230V and 208/230115V units are available with 145 and 175 PSI maximum system pressure, 85, 180, 450 and 900 RPMs and 1-1/4, 1-1/2 and 2-1/2 inch flange connections.
