The next level of the Design Envelope technology, the range from 1hp to 10hp, and the new line of Tango pumps is a completely integrated offering designed to further reduce the first installed costs as well as ongoing lifetime costs by more than 30% over traditional approaches.
New features include a new hydraulic design optimized for intelligent variable speed operation, the new Armstrong iECMpermanent magnet motors with integrated drive and controls that deliver IE4 levels of energy efficiency, extended by the on-board intelligence.
In addition, the new range has improved efficiency of between 3 - 6% on hydraulics and between 2 - 7% on motor efficiency for reduced energy usage and carbon footprint. There is also built-in parallel sensorless pump control capabilities that provide best-efficiency staging and built-in redundancy to deliver up to 30% savings over traditional duty-standby approaches.
The company says that the new Tango line represents the embodiment of the complete Design Envelope technology capabilities, delivering the pinnacle of operational performance.
