Armstrong Fluid Technology introduced two new series of Horizontal End Suction Design Envelope (DE) Pumps featuring Sensorless integrated controls. Both the DE 4200H and DE 4280 Series include Armstrong Design Envelope technology Sensorless control and enhanced connectivity to BAS to achieve efficiency improvements. The DE 4200H pumps are supplied with split-couplings and outside balanced seals while the DE 4280 pumps use a close-coupled design. Pumps include integrated controls eliminating the need for VFD wall space or mounting with extra cable runs. They also feature built-in harmonic mitigation, soft start, and motor adaptation. They are available to 125hp/90kW (DE 4200H) and 7.5hp/5.5kW (DE 4280). No field alignment necessary following installation or field service (DE 4200H)
