Designed for circulating liquids in heating systems.\u003c\/p\u003e\u003cp\u003eIt features a constant pressure control mode with three settings. The intuitive one-button operation and LED display makes the selection of the settings easy. The large LED display shows the current energy consumption in Watts and estimated flow in gallons per minute.\u003c\/p\u003e\u003cp\u003eALPHA1 materials and design are resistant to blockage from magnetite found in hydronic systems.\u003c\/p\u003e\u003cp\u003eThe robust startup enables ALPHA1 to continuously attempt to restart – indefinitely – in blocked rotor conditions.\u003c\/p\u003e\u003cp\u003eALPHA1 is complete with an integrated check-valve, and nut captures for flanges.\u003c\/p\u003e\u003cp\u003eFor power connection two options are available with either line cord or terminal box for conduit connections.\u003cbr\u003e\u003cimg
