1900e Series ECM High-Efficiency Circulators

1911ecm™ & 1915ecm™

1911ecm™ & 1915ecm™ High-Efficiency ECM Circulator Pumps

The 1900e® Series are self-sensing, close-coupled, mechanically sealed in-line circulator pumps that exceed industry and efficiency standards with an advanced hydraulic design. They feature a high-efficiency volute, ECM motor, and integrated frequency drive. Simple yet versatile control options include constant pressure, constant speed, proportional pressure, 0-10Vdc, and parallel pump alternation. These standard features combined with the intuitive user interface allow for quick start-ups achieving optimum system efficiency and maximum comfort. These pumps are available in Ductile Iron for closed-loop hydronic heating and cooling systems or Stainless Steel, NSF Commercial Hot Certified for DHW applications.
