Grundfos’ new MLE motor for the Hydro MPC BoosterpaQ systems include ECM technology and covers 1 through 15 hp in three-phase 460 to 480 volts and up to 2 hp in one-phase 200 to 240 volts. The motors exceed IE5 motor efficiency standards, currently the highest level for electrical motors. BoosterpaQ systems use controls to stop pumps during low flow, run in a more economical mode, stage pumps on when it is more efficient, and lower setpoint pressure at lower flows when pipe friction loss is less. 800/921-7867;
