When looking for a pump, select a mechanically-sealed end-suction unit with 3 phase motor. A pump-motor unit makes it possible to avoid a belt drive, reduces energy losses, is easier to install, costs less, and lasts longer than a system with a belt drive. Most pumps, even for powers of less than 1 kW, are supplied with three-phase induction ...

All ACQ580 drives are current rated devices. The HP ratings provided are for reference only and are based on typical 4-pole motors at nominal voltages (NEC Table 430.250). If full motor torque is required, ensure the drive has a continuous current rating equal to, or greater than the full load amp rating of the motor.

The listed motor power values (3…630kW) are for standard IEC motor sizes. The Efficiency Tool selects automatically ABB M3000 motor (if available) according to given output power and pole number. The latter is determined by the rotating speed of the existing motor and it is assumed that it remains the same also in the new motor.
