Pump High Efficiency 1 1/4"

  • High Efficiency

    Utilizes an advanced ECM motor to consume up to 85% less electricity than standard pumps.

  • Multiple Modes

    Features Auto, Proportional Pressure, Constant Pressure, Constant Speed, and Night Setback settings.

  • Integrated LED

    Provides real-time digital feedback on wattage, flow rates, and current RPM.

  • Robust Construction

    Includes a 1 1/4" NPT stainless steel flange union for long-lasting, low-noise operation.

  • External Control

    Supports PWM input signals for seamless integration and safety within boiler and heating systems.

  • Plug-and-Play

    Designed for easy handling and quick installation with direct connection to boilers or heat pumps.

Adaptive Performance

The pump features intelligent self-adjusting modes that automatically balance flow and pressure according to the specific demands of the heating system.

Thermal Resilience

Engineered to operate reliably across a wide liquid temperature range from -10ºC to 110ºC (10ºF to 230ºF) for diverse applications.

Scalable Flow

This model allows for doubling pumps in series to effectively double the system flow rate, providing flexibility for larger installation requirements.

Operational Safety

Built-in safety features include hysteresis protection and a failsafe that runs the pump at maximum speed if control cables are damaged.

Seadona 1-1/4 circulator pump

Installed this pump with DUO Pellet boiler, it has different curves you can select for how you want it to operate. It was easy to wire into the controller. Runs on 220V 50Hz which is the same as what powers the boiler controller. I've only been running the pump for about a week now, so can't comment on longevity.

Great pump, made it easy to setup with existing Pellet 50 boiler.
