Lowara has announced that the pump range equipped with two poles motors from 3 to 22 kW (three phase) and 2.2 kW (single phase), or four poles motors from 1.1 to 15 kW, will be available with its new PLM high efficiency electric motors. The move will improve both, the cost-effectiveness, environmental credentials and operating performance of the Lowara pump range for residential and commercial applications. The electric PLM motors have efficiency values that fall within the range normally referred to as efficiency 1 and comply with the targets set by a voluntary stand-ard. The motor quality and reliability is actually higher than in previous equivalent motors, with less heating within the motor. In combination with the Hydrovar variable speed controller, the efficiency of Lowara’s pumps can be even more dramatically improved. Hydrovar can control up to eight pumps with intelligent drive, all from a single pump-mounted unit.
