Alpha2 recirculator pump
High efficiency circulator with encapsulated rotor, designed for the circulation of fluids in domestic heating systems. With an excellent energy efficiency index (EEI), well below the reference point of the ERP, guarantees important energy savings.
Characteristics
- Includes Autoadapt, which provides unprecedented comfort levels with the lowest possible energy consumption, which makes the implementation safe and simple.
- Nightlife function that saves energy
- The manual summer mode saves energy during the summer and guarantees a safe start in the heating season.
- The intuitive operation with a single button simplifies the selection of any control mode.
- No need for external engine protection, reducing installation time
- Starting with a high motor torque improves ignition in hard conditions.
- 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 with pumps are supplied to minimize heat loss in heating systems.
- The balanced hydraulic through the temporal use of Alpha Reader and the GRUNDFOS GO BALANCE application allows installers a rapid and simple hydraulic balance.
The Alpha2 combination with the other two components, Alpha Reader and the GRUNDFOS GO BALANCE application, allows the installers to carry out a rapid and simple balanced hydraulic balance without compromising the reliability, efficiency and ease of installation.
Autoadapt function continuously adapts the pump yield to real heat demand, that is, to the size of the system and to the changing heat demand. The function will find the appropriate adjustment to offer optimal comfort with minimal energy consumption. It contributes to a quick, safe and simple implementation.
In addition, the pump also has three control modes, each with three configurations:
- Proportional pressure control
- Constant pressure control
- Constant curve mode
The screen shows the real energy consumption in watts or the real flow in m3/h, as well as alarms and notices. LEDs indicate the current state of operation.
Automatically activate the nocturnal function reduces engine speed to save energy. Automatic change depends on a change in the temperature of the feed pipe.
Manual summer mode; Once enabled, the pump starts automatically low speed to avoid rotor lock. In addition, save energy at the same time.
It is a pump with an encapsulated rotor, which means that the pump and the engine form an integral unit. The bearings are lubricated with the pumped liquid, guaranteeing operation that does not require maintenance. The pump includes dry operation protection.
The pump has a ceramic axis and radial bearings, carbon thrust, rotor shirt, support plate and lining of the stainless steel rotor and driver of compound material, and all of them contribute to a long shelf 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 a control box and an integrated control panel, adapts to the most common facilities.
The pump housing is made of cast iron and galvanized to improve corrosion resistance.
The engine is permanent magnets/compact stator, characterized by its high efficiency. The pump speed is controlled by an integrated frequency converter, which is incorporated into the control box.
