ALPHA SOLAR circulation pump for solar heating systems 15-75 130 G1 98989298

Circulation pump for solar systems – efficient heating and energy saving

The Grundfos ALPHA SOLAR 15-75 130 circulation pump is an efficient solution designed for use with solar heating systems. Designed to optimize energy consumption and ensure reliable operation, it works well in both domestic and commercial installations. Its construction allows for efficient circulation of the heating medium, which translates into higher efficiency of the entire system.

Construction and application

The ALPHA SOLAR pump is characterized by its compact dimensions and ease of installation. A mounting length of 130 mm makes it easy to integrate with existing installations. It is intended for circulating water in solar systems, where precise flow control and minimizing energy losses are crucial. The ability to adjust the rotational speed using a PWM signal from a solar controller allows you to adapt the pump's operation to current weather conditions and heat demand. This ensures that the system operates efficiently regardless of the intensity of sunlight.

Advantages of the Grundfos ALPHA Solar pump

• High energy efficiency: An EEI index of 0.20 guarantees minimal power consumption and reduced operating costs.
• Versatility: Suitable for heating commercial buildings, single-family homes and industrial installations.
• Quiet operation: Provides comfortable use thanks to the low noise level during operation.
• Durability and reliability: Made of high-quality materials, such as gray cast iron (pump body) and composite (impeller), which ensures a long service life of the device.
• Simple installation: Compact dimensions and a standard G 1 inch connection make installation easy even in tight spaces.
• Wide temperature range: Operates in a liquid temperature range from 2°C to 110°C and an ambient temperature range from 2°C to 70°C, which ensures its versatility.
• Maintenance-free: The pump design minimizes the need for maintenance, which translates into saving time and costs.
• Protections: It has a protection class of IP65, which guarantees resistance to moisture and dust.

In addition, the pump has CE, VDE and EAC approvals, confirming its compliance with European safety and quality standards. Adapted to operate at 230V (1 phase). However, remember that electrical installation work should be performed by a qualified electrician in accordance with applicable regulations (VDE 0100).
