Pump High Efficiency 1"

Main Features

  1. High Energy Efficiency

    Powered by a permanent magnet ECM motor that can reduce electricity use by up to 85 percent while maintaining an EEI of 0.20 or lower.

  2. Intelligent Operating Modes

    Supports Auto, Proportional Pressure, Constant Pressure, Constant Speed, and Night Setback modes for adaptable hydronic performance.

  3. Real-Time LED Display

    The built-in LED display shows live operating data including watts, flow rate, and motor speed for fast system checks.

  4. Robust Construction

    Built with a compact pump body and 1 inch NPT stainless steel flange unions for long-term durability in demanding HVAC systems.

  5. External PWM Control

    Accepts an external PWM control signal for tighter integration with advanced boiler, heat pump, and hydronic control strategies.

  6. Compact & Easy Installation

    Its small footprint and plug-and-play form factor simplify installation in tight spaces across boilers and HVAC mechanical rooms.
