Description
ALPHA2 25-40 180 High efficiency circulator with encapsulated rotor, designed for the circulation of liquids in domestic heating systems. With an excellent energy efficiency index (EEI), well below the ErP reference point, it guarantees significant energy savings.
Details
More information
It includes AUTOADAPT, which provides unprecedented levels of comfort with the lowest possible energy consumption, making commissioning safe and easy. Energy saving night mode function Manual summer mode saves energy during summer and ensures a safe start in the heating season. Intuitive one-button operation simplifies selection of any control mode. No need for external engine protection, reducing installation time High torque starting improves ignition in harsh conditions. Maintenance-free due to encapsulated rotor design and use of solid components The ALPHA connector allows quick and easy electrical installation. Insulation housings are supplied with the pumps to minimize heat loss in heating systems. Hydraulic balancing through the temporary use of ALPHA Reader and the Grundfos GO Balance app allows installers quick and easy hydraulic balancing. The combination of ALPHA2 with the other two components, ALPHA Reader and the Grundfos Go Balance app, allows installers to perform quick and easy hydraulic balancing without compromising reliability, efficiency and ease of installation.
The AUTOADAPT function continuously adapts the performance of the pump to the actual heat demand, that is, to the size of the system and to the changing heat demand. The function will find the appropriate setting to offer optimum comfort with minimal energy consumption. It contributes to a quick, safe and easy start-up.
In addition, the pump also has three control modes, each with three settings: proportional pressure control constant pressure control constant curve mode The display shows the actual energy consumption in watts or the actual flow rate in m3 / h, as well as alarms and warnings. LEDs indicate current operating status.
Automatically activating the night mode function reduces motor speed to save energy. The automatic change depends on a change in the temperature of the supply pipe.
Manual summer mode, once enabled, the pump automatically starts frequently at low speed to avoid rotor blockage. Plus, it saves energy at the same time.
It is an encapsulated rotor pump, which means that the pump and motor form an integral unit. The bearings are lubricated with the pumped liquid, guaranteeing maintenance-free operation. The pump includes protection against dry running.
The pump has ceramic shaft and radial bearings, carbon thrust bearing, rotor sleeve, support plate and rotor liner in stainless steel and composite impeller, all of which contribute to long service life.
The pump is self-bleeding through the system, which contributes to easy start-up. Its compact design, which features a pump head with a built-in control box and control panel, adapts to most common installations.
The pump casing is made of cast iron and galvanized to improve corrosion resistance.
The motor is a permanent magnet / compact stator motor, characterized by its high efficiency. The pump speed is controlled by an integrated frequency converter, which is built into the control box.
