Armstrong has extended its IVS range of sensorless control pumps to include models with variable speed drives up to 55 kW. Previously, the drives were only available up to 7.5 kW.
Armstrong is also launching a range of standalone inverters, the IVS102, to offer specifiers variable speed pumping up to 450 kW maximum power. These inverters which automatically calculate the building demand and adjust the speed of the drives accordingly.
The IVS pump range from Armstrong has a reduced complexity of system design without the need for remote VFDs and sensors, faster maintenance and a 50% reduction in seal costs. Energy consumption can be reduced by over 20% compared to maintaining a constant pressure across the pump.
