Circulation pump ALPHA SOLAR series

centrifugalwatermagnetic-drive

ALPHA SOLAR is a circulator pump designed for thermal solar systems. It features three constant-curves modes, and the speed can also be controlled by a low-voltage PWM signal from a solar controller. ALPHA SOLAR for a high-efficiency solar water system The high-efficiency ALPHA SOLAR circulator pump from Grundfos comes with a permanent magnet motor and is designed to be integrated in thermal solar pump systems. Four constant-curve settings are available and the speed can be controlled by a low-voltage PWM signal to optimise solar harvesting and reduce power consumption. Grundfos ALPHA SOLAR offers very simple installation and a low noise level. This high-efficiency and reliable pump is built 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 optimise solar harvesting and ensure minimal power consumption. Easy Access A manual deblocking screw is accessible from the front of the pump. Remote troubleshooting A dry-running warning is available as a PWM feedback signal. Easy operation Very simple installation, low noise level and no maintenance required.
