ALPHA SOLAR Circulator Pump 25-75 130

ALPHA SOLAR 25-75 130 1x230V 9H Pump. The new Grundfos ALPHA SOLAR sets new standards for energy efficiency in solar water circulation for domestic homes. Thanks to its extremely silent permanent magnet motor and the ability to adjust its performance curves, the consumption of this pump is a third of that offered by previous generation circulators. Furthermore, the speed of the new Grundfos ALPHA SOLAR can be controlled with a Pulse Width Modulation (PWM) signal from a solar control unit to optimise energy collection and system temperature. As a result, the pump's electricity consumption is significantly reduced, with a minimum of 2 W. P1 max. of ALPHA SOLAR xx-75 = 45W compared to P1 max. of UPS SOLAR xx-80 = 120W.
