  1. Grundfos Alpha3 15-50/60 Domestic Circulator - 130mm - 240v

    GR-99371966

    Grundfos - ALPHA3 15-50/60 Domestic Circulator - 130mm - 240V - Cast Iron

    ALPHA3 15-50/60 130

    Grundfos ALPHA3 high-efficiency circulator pumps are designed for circulating liquids in heating systems. With an energy efficiency index (EEI) well below the ErP benchmark, they ensure substantial energy savings.

    ALPHA3 is completely controlled with Grundfos GO Remote via Bluetooth, which gives you step-by-step assistance to pump configuration, maintenance and commissioning, including:

    • Warning and alarm status
    • Pump venting process
    • Scheduling for when the pump should operate incl. summer mode
    • Operating and control modes

    The pump features radiator and underfloor-heating control modes with AUTOADAPT, which continuously adjusts the pump performance to the actual heat demand, i.e. the size of the system and changing heat demand during the year. The AUTOADAPT feature finds the setting that provides optimal comfort with minimal energy consumption and makes the commissioning fast, safe, and straightforward. ALPHA3 also offers proportional-pressure, constant-pressure and constant-curve control modes with setpoint adjustment anywhere between the maximum and minimum curve of the chosen setting.

    Furthermore, ALPHA3 can communicate directly with the Grundfos GO Balance app, enabling installers to easily perform hydronic balancing of radiator and underfloor-heating systems. ALPHA3 is furthermore compatible with ALPHA Reader and the Grundfos GO Balance app, enabling the installers to easily perform hydronic balancing of radiator and underfloor-heating systems.

    With the self-operating night setback function, the pump automatically changes between normal duty and night setback. The changeover depends on the flow-pipe temperature controlled by the heating appliance.

    The design and the chosen materials of the pump contribute to long life. The pump is self-venting through the system, which contributes to straightforward commissioning. The space-efficient design, featuring a pump head with an integrated control box, fits into most common installations. Pump and motor form an integral unit without a shaft seal. The bearings are lubricated by the pumped liquid. These constructional features ensure maintenance-free operation.

    The active dry-running protection feature protects the pump against dry running during startup and normal operation. In case of a blocked rotor, the pump will continuously attempt to restart with highest possible torque.

    Pump housings made of Cast Iron are electrocoated to improve corrosion resistance. The motor is a synchronous permanent-magnet/space-efficient-stator motor characterised by high efficiency. The pump speed is controlled by an integrated frequency converter incorporated in the control box.

    Insulating shells are supplied with pumps to minimise heat loss in heating systems.

    Suitable for: Commercial air conditioning, District heating
