Grundfos ALPHA SOLAR circulator for a high efficiency solar water system.
ALPHA SOLAR is a circulator 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 simple installation and a 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 high efficiency
The PWM signal generates an analog signal using a digital source to control pump speed, performance and to optimize solar collection and ensure minimum energy consumption .
Easy Access
A manual release screw is accessible from the front of the pump.
Remote Troubleshooting
A dry run warning is available as a PWM feedback signal.
Easy handling
Very simple installation, low noise level and maintenance-free.
