ALPHA SOLAR is a circulating pump designed for solar thermal systems. It has three constant curve modes, and it is also possible to control the speed using a low voltage PWM signal from a solar controller.

Grundfos ALPHA SOLAR offers very easy installation and low noise level. This highly efficient and reliable pump is designed to be maintenance-free with durable ceramic bearings and shaft, as well as corrosion-resistant stainless steel components.

Reliable and highly efficient
The PWM signal generates an analog signal using a digital source to control pump speed, performance and to optimize solar gain and ensure minimum energy consumption.

Easy access
A manual release screw is accessible from the front of the pump.

Remote troubleshooting
A dry running warning is available as a PWM feedback signal.

Easy handling
Very easy installation, low noise level and no maintenance.

    Fantastic service. I highly recommend this company. What I appreciated was the quick responses, and the technical capability of Federico. As an engineer I get tired of people only interested I selling. Q-Tec was not like this. They took the time to recommend a solution AND. Support it with good solid science.
    Highly recommend this company.

    This company has really helped me forward with serious technical advice on deciding what replacement pump to order for my pool.

    Actually, they actively prevented me from buying the conservative more noisy solution that would also have cost me more on energy consumption in the next years.

    De warmtepomp die Q-tech ons aanbevolen heeft werkt top ! Zij werken alleen met topkwaliteit . Ons zwembad warmt met 1 graad per uur op - beloofde resulten worden gehaald. En we kunnen altijd op het team rekenen als er problemen opgelost moeten words. Dan zetten ze alles opzij en lossen zij het problem op. Dankjewel voor jullie service !

    Really happy with the technical support provided by Federico which correctly identified the issue I was having with my one year old pump.

    The accurate support (in English) and over WhatsApp really helped me navigate a stressful 2 day period in not having running water. Thank you!
