The 1915e™ ECM High-Efficiency Circulators   

Self-Sensing, Close Coupled, Mechanically Sealed In-Line Pump
The ECM 1915e is a self-sensing, close coupled, mechanically sealed in-line pump that exceeds industry and efficiency standards with an advanced hydraulic design. It features 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. The 1915e is available in Cast Iron for closed loop hydronic heating and cooling systems or Stainless Steel, NSF Commercial Hot Certified for DHW applications.
