Circulator Pump Alpha3 25-60 180
Description
Circulator Pump Grundfos Alpha3 25-60 180
ALPHA3 is a circulator pump designed for heating systems and is completely controlled with the Grundfos GO Remote app which allows to easily hydronically balance radiator- and underfloor-heating systems.
Suitable for
- Commercial heating
- Basement
- Bathroom
- Domestic heating
- Kitchen
- Living space
- Loft
- Industrial heating
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:
- Operating and control modes.
- Scheduling for when the pump should operate incl. summer mode.
- Pump venting process.
- Warning and alarm status.
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 easy. 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 automatic 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 easy commissioning. The compact 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/compact-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.
