ALPHA SOLAR 15-75 130
The new ALPHA SOLAR is designed to be integrated into all types of solar thermal systems with variable (corresponding flow) or constant flow.
High efficiency ECM pumps (electronically commutated motor), such as ALPHA SOLAR, do not have to be regulated in speed by a special external regulator that varies or pulses the supply voltage.
The speed can be controlled by a low voltage PWM (Pulse Width Modulation) signal from a solar controller to optimize the solar energy supply and system temperature.
As a result, the energy consumption of the pump will be reduced considerably.
If no PWM signal is available, ALPHA SOLAR can be set to a constant speed, and only be turned on and off by the controller.
Characteristics:
- Constant speed.
- PWM profile.
- PWM signal is a method of generating an analog signal using a digital source.
- Low EEI (energy efficiency index).
- Without maintenance.
- Low noise level.
- Very simple installation.

Overview Grundfos Alpha1
The Grundfos ALPHA1 represents the frontier of innovation in the field of circulation pumps for domestic and commercial heating systems. This series, renowned for its reliability and energy efficiency, stands out for its ability to automatically adapt to changes in the system, ensuring optimal living comfort and significant energy savings. ALPHA1 L technology uses a permanent magnet motor combined with speed control via inverter, which allows the flow rate to be adjusted based on the real needs of the system. Furthermore, thanks to its compact design and easy user interface, installation and maintenance become simple and quick operations, reducing intervention times and management costs. The use of "alpha 1 grundfos" pumps is a sustainable choice that actively contributes to the reduction of CO2 emissions, thus positioning the user at the forefront of the transition towards greener technologies. With Grundfos ALPHA1, it is possible to achieve that perfect balance between living comfort, energy efficiency and respect for the environment.
Features and Benefits of the Grundfos ALPHA1 L Series
The Grundfos ALPHA1 L series represents the pinnacle of innovation in terms of circulation pumps for domestic heating systems and air conditioning applications. These pumps are designed to offer unparalleled energy efficiency, thanks to AUTOADAPT technology which allows automatic regulation of performance based on the real needs of the system, thus guaranteeing significant savings on energy costs. The ALPHA1 L model integrates advanced features such as speed control with three fixed settings and proportional differential pressure mode, which adapt perfectly to load variations in complex systems.
Furthermore, the advantages are not limited only to aspects related to energy consumption: the extreme ease of installation and almost non-existent maintenance make Grundfos ALPHA1 L pumps a practical and reliable solution. The compact and ergonomic design facilitates integration into various environments of use, while the robustness of the materials ensures long life. Built-in wireless communication allows for constant monitoring and easy configuration through mobile devices, further simplifying interaction with the pump.
The use of the ALPHA1 L series therefore has a positive impact not only on living comfort but also on the environment, helping to reduce CO2 emissions. In summary, choosing a Grundfos ALPHA1 L pump means opting for cutting-edge technology that offers high performance, energy efficiency, simple installation and low maintenance: characteristics that make it ideal for any modern heating or air conditioning system.
Installation and Maintenance: Practical User Guide
Installation and maintenance of the Grundfos ALPHA1 series are simplified processes, designed for efficiency and reliability. When installing the ALPHA1 circulation pump, it is important to carefully follow the instructions provided by Grundfos, starting from the vertical position of the motor, which is essential to avoid damage to the bearings and prolong the useful life of the device. It is advisable to use isolation fittings to facilitate any maintenance operations without having to empty the entire system. Once installed, the ALPHA1 pump stands out for its intuitive operation; by selecting the desired control mode - constant, proportional or AUTOADAPT - energy consumption is optimized based on the actual needs of the system.
Routine maintenance of the Grundfos ALPHA1 is minimal thanks to its robust design and build quality. However, it is advisable to periodically check the operation of the pump and clean the integrated filter to prevent blockages that could compromise performance. Furthermore, the ALPHA1 L series pumps are equipped with a rotor unlocking function that can be activated manually in the event of prolonged system downtime, thus ensuring long life and reducing the risk of failure.
Finally, we would like to remind you that correct installation and regular maintenance not only ensure optimal operation but also contribute to maintaining high energy efficiency of the heating system over time. For any doubt or specific need, Grundfos offers qualified technical support and detailed documentation to assist the user in every phase of using the ALPHA1 pump.
