The ecocirc 19-16 variable speed ECM circulator has onboard intelligence that will automatically adjusts pump performance to ensure the highest efficiency.

The product’s built-in intelligence supplies the motor with the frequency and voltage for optimum performance.

The permanent magnet in the motor ensures no power is wasted to magnetize the rotor.

The product has three modes of operation: proportional pressure is the factory default mode and recommended for systems with high-pressure variations; constant pressure maintains the selected differential pressure at any flow rate and is recommended for systems with relatively small variations in pressure;  and constant speed maintains a fixed speed regardless of demand.
