Armstrong variable-speed pumps go to 250 kW
Armstrong has extended its IVS and IVS Sensorless ranges of integrated variable-speed pumps from 55 kW up to 250 kW. These pumps have integrated variable-speed drives and can be controlled by transducers, BMSs or without a sensor for the Sensorless models. The installed cost for an IVS Sensorless pump is said to be typically 25% lower than a conventional vertical inline pump with separate variable-speed drive and remote sensor.
IVS Sensorless models in the 4300 and 4302 Series have integrated inverters that automatically control pump speed according to demand. This built-in control has valuable benefits for retrofits, simplifying the migration from fixed to variable speed.Energy savings of over 50% can be expected.
