MAGNA 32-100The MAGNA 32-100 variable-speed wet rotor circulator from Grundfos has a permanent magnet motor, reducing power consumption. The motor design delivers a starting torque four times higher than the standard induction motor while avoiding slippage and allowing flows from 0 to 52 gpm and a noise level less than 35 db. The AUTOADAPT feature controls this pump performance within a defined performance range, ensuring the lowest possible energy consumption without sacrificing comfort. Current conditions can be analyzed and adjusted with an integrated frequency converter. A 10-ft cord connects the circulator to a wall outlet with no need to open a terminal box.
