Alpha3 circulating pump

High efficiency circulator with encapsulated rotor, designed for liquid circulation in heating systems. With an excellent energy efficiency index (EEI), well below the reference point of the ERP, guarantees important energy savings.

The ALPHA3 pump carries radio by Bluetooth and can be completely controlled by an intelligent device through the GRUNDFOS GO remote application. It offers step -by -step assistance for the configuration, maintenance and implementation of the pump.

The Alpha3 is communicated directly with the Grundfos Go Balance application, which allows installers to carry out a rapid and simple balanced hydraulic.

The autoadapt function integrated in radiator mode and radiant soil continuously adapts the pump yield to real heat demand, that is, to the size of the system and to the changing demand for heat. The Autoadapt function will find the appropriate adjustment to offer optimal comfort with minimal energy consumption. This also guarantees a quick, safe and simple implementation.

Functions

• Radiator mode with Autoadapt: ​​The easiest option for two chain radiator heating systems
• Radiant soil mode with Autoadapt: ​​the simplest option for radiant soil heating systems
• Combined radiator and radiant soil for systems with a combination of heating systems
• For programming and summer mode, a clock allows you to select in real time when the pump should work and when to save energy
• Simple user interface: The pump is completely handled from the GRUNDFOS GO remote application
• Alarm and registration of notices with assistance through Grundfos Go Remote
• No need for engine external protection, thus reducing installation time
• Start with a high motor torque improves ignition in hard conditions
• Dry operation protection during ignition and normal operation
• No maintenance need thanks to the design of encapsulated rotor and use of solid components
• The alpha connector allows a quick and simple electrical installation
• Insulation housings are supplied with pumps to minimize heat loss in heating systems.

In addition, the pump also has three control modes with progressive adjustment adjustment, which allows you to adjust the pump configuration at a certain work point

• Proportional pressure control
• Constant pressure control
• Constant curve mode

The screen shows the real power consumption in watts or the real flow in m3/h. LEDs indicate the current state of operation.

The pump design and the selected materials contribute to a longer life. The pump is a highway through the system, which contributes to a simple implementation. Its compact design, which has a pump head that carries an integrated control box, adapts to the most common facilities. The pump and engine form an integral unit without closure. The bearings are lubricated with the pumped liquid. These constructive characteristics guarantee a operation that does not require maintenance.

The pump housing is made of cast iron. The pump housing and the pump head are galvanized to improve corrosion resistance.

The engine is permanent magnets, characterized by its high efficiency. The pump speed is controlled by an integrated frequency converter, which is incorporated into the control box.

The reference point for the most efficient circulars is IEE ≤ 0.20.
