Description

Grundfos variable speed circulator ALPHA2 32-80 180 code 99411263

ALPHA2 32-80 180

Product code 99411263

High efficiency fixed rotor circulator, designed for the circulation of liquids in heating systems. With a world-class energy efficiency index (EEI) well below the ErP benchmark, it guarantees significant energy savings.

Features

  • AUTOADAPT which provides the highest levels of comfort with the lowest possible energy consumption and makes commissioning easy and safe
  • Night function that saves energy
  • The manual summer mode saves energy during the summer and ensures a safe start into the heating season
  • Intuitive one-button operation makes it easy to select any control mode
  • No external motor protection needed to reduce installation time
  • High torque starting improves starting in difficult conditions
  • Maintenance-free thanks to the encapsulated rotor design and the use of robust components
  • The ALPHA plug makes electrical installation quick and easy
  • Insulating shells are supplied with the pumps to minimize heat loss in heating systems
  • Hydronic balancing through temporary use of ALPHA Reader and the Grundfos GO Balance app allows the installer to perform a quick and easy hydronic balancing

When using ALPHA2 with two other components, ALPHA Reader and the Grundfos GO Balance app, it allows installers to perform quick and easy hydronic balancing, without compromising reliability, efficiency and ease of installation.

The AUTOADAPT function continuously adapts the pump performance to the actual heat demand, i.e. the size of the system and the change in heat demand over the year. The function will find the setting that provides optimal comfort with minimum energy consumption. It contributes to quick, safe and easy commissioning.

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 actual energy consumption in Watts or actual flow in m3 / h, as well as alarms and warnings. The LEDs indicate the actual operating status.

The night setback function, when enabled, automatically reduces the motor speed to save energy. The changeover depends on a change in the flow pipe temperature.

Manual summer mode; once enabled, the pump will automatically start frequently at low speed to avoid blocking of the rotor. At the same time, it saves energy.

The pump is of the encapsulated rotor type, which means that the pump and motor form an integral unit. The bearings are lubricated by the pumped liquid ensuring maintenance-free operation. The pump is equipped with dry-running protection.

The pump has a ceramic shaft and radial bearings, carbon thrust bearing, stainless steel rotor, bearing plate and rotor liner, composite impeller, which contribute to a long service life.

The pump will automatically vent through the system, which contributes to easy commissioning. The compact design featuring the pump head with integrated control box and control panel fits the most common installations.

The pump housing is made of cast iron and electro coated to improve corrosion resistance.

The motor is a compact permanent magnet / stator synchronous motor featuring high efficiency. The pump speed is controlled by an integrated frequency converter built into the control box.

GRUNDFOS ALPHA2 overview

The Grundfos ALPHA2 represents a milestone in the panorama of solutions for the circulation of domestic and commercial heating. This heat pump is synonymous with energy efficiency and optimized performance, thanks to its ability to automatically adapt to the various needs of the heating system in which it is installed. The integrated AUTOADAPT technology automatically selects the necessary flow rate, reducing energy consumption by up to 70% compared to traditional models. Furthermore, the intuitive display makes configuring and monitoring operations a simple procedure for end users. Durability and reliability are further guaranteed by the Grundfos brand, world leader in pumping solutions, which with the ALPHA2 series manages to combine technological innovation and environmental sustainability.

Technical Characteristics and Advantages of the ALPHA2

The Grundfos ALPHA2 pump represents a cutting-edge solution for water circulation in domestic heating systems, standing out for its innovative technical characteristics and the numerous advantages it offers. This model is equipped with AUTOADAPT technology, which allows the pump to automatically adjust performance based on the actual needs of the system, thus optimizing energy consumption and ensuring constant comfort. Furthermore, the grundfos alpha 2 is designed to be extremely quiet during operation, contributing to a more pleasant home environment. Thanks to its ability to interface with domestic energy management systems, ALPHA2 is also a precious ally for those seeking intelligent management of their home.

The advantages of using the Grundfos ALPHA2 pump do not stop at energy savings and comfort. Installation is made simple thanks to an intuitive control panel and a compact construction that facilitates integration into the existing system without the need for invasive modifications. It can operate effectively in different types of systems thanks to its versatility of application which includes underfloor heating systems, radiators and air conditioning. Durability is ensured by the build quality typical of Grundfos products, while compatibility with the Grundfos GO app makes it possible to remotely monitor and adjust pump settings, thus offering complete and efficient control to the system owner.

ALPHA2 Pump Installation and Configuration Guide

The installation and configuration of the Grundfos ALPHA2 pump are key processes to ensure optimal operation of your home heating system. First of all, it is essential to choose the correct size of the pump based on the specific needs of the system. The pump must be installed on the return of the heating circuit, before the boiler, to avoid damage due to high temperatures. During installation, make sure the arrow on the pump body is oriented in the direction of water flow.

Once positioned correctly, connect the pump to the electrical system respecting current regulations. Installation requires particular attention to the sealing and insulation of the hydraulic and electrical connections to prevent leaks and ensure safety. With Grundfos ALPHA 2 AUTOADAPT technology, the pump is able to automatically adapt to changes in system demand, thus ensuring reduced energy consumption and optimal performance.

The configuration can be further customized through the integrated control panel, which allows you to select between different operating modes based on specific needs: fixed speed mode, pressure proportional mode or AUTOADAPT mode. The use of the AUTOADAPT mode is recommended to maximize energy efficiency since the pump autonomously regulates its operation based on the real needs of the system.

Finally, it is important to periodically check the operation of the Grundfos ALPHA2 to ensure that it is working in optimal conditions. Carefully following the instructions provided in the user manual will be essential to prolong the useful life of the pump and maintain a high level of efficiency over time.
