Taco VR1816 ECM High-Efficiency Circulator

The Taco Comfort Solutions® 00e™ Series VR1816 ECM High-Efficiency Circulator (Model VR1816) is an infinitely variable, wet-rotor commercial-grade heating pump engineered to reduce electrical power consumption by up to 85% compared to traditional multi-speed standard circulators. Powered by an advanced permanent magnet motor design, the VR1816 provides six distinct pressure presets alongside infinitely variable fixed-speed throttling to allow field technicians to perfectly dial in system design parameters with the single turn of a selector dial.

Key Performance Features:

• Smart 3-Mode Operating Logic: Configured for high operational adaptation, running in Infinitely Variable Fixed Speed (ideal for zoning with individual circulators), Constant Pressure (best for zone valve applications), or Proportional Pressure (optimized for panel radiators with TRVs).
• Exclusive SureStart® Mechanical Safeguard: Features a built-in "no-callback" automatic unblocking sequence that actively purges trapped system air pockets and breaks free internal mineral locks to guarantee smooth start-up sequences.
• Integrated Safety Diagnostics & Check Valve: Features a 5-color smart external LED panel providing real-time mode confirmation and immediate troubleshooting codes, complete with an internal Integral Flow Check (IFC®) to arrest ghost-venting thermals.

Installation Environment Profile: Constructed with a rugged cast iron wet-rotor volute, this premium high-efficiency pump is strictly rated for closed-loop hydronic space heating or commercial water/glycol solutions up to 50% capacity. (Not designed for open-loop domestic potable water or raw chilled infrastructure loops).
