The Grundfos ALPHA2 circulator pump series can withstand the tough conditions in a heating system, and with four newly added features, it just got even tougher.  First it has a robust start-up, which shakes free any impurities before the pump starts at the beginning of the heating season.  Next is summer mode, and this is an adjustment of the pump’s performance in the summer to the warmer temperature outside – giving customers extra energy efficiency.  It also includes a magnetite resistance, which ensures that no small pieces of metal get stuck in the pump’s vital parts when they are magnetise.  Lastly is dry-running protection, which makes sure the pump never runs without liquid in the system.  This pumps new features are added to the already unrivalled energy efficiency, easy installation and the fact that ALPHA2 covers both your heating demands and up to 90 % of your air-conditioning and cooling demands. Features: Simple push button Control enables the ALPHA2 to be programmed in one of 3-constant speed, 3-constant pressure, or AUTOADAPT control modes AUTOADAPT selects best performance curve for efficiency and comfort Flow meter for trouble-shooting and balancing Large LED display shows the current energy consumption in Watts and estimated flow in gallons per minute ALPHA2 is complete with an integrated check-valve, foam insulation jacket, and nut captures for flanges Robust startup enables the ALPHA2 to continuously attempt to restart – indefinitely – in blocked rotor conditions Innovative plug simplifies pump connection Insulation shells included ALPHA2 can be used as a replacement for more than 30 competitor pump models Applications: Systems with constant or varying flow One pipe systems Two pipe systems Underfloor-heating Domestic hot-water recirculation Systems where night setback is required GRUNDFOS ALPHA2 SERIES CIRCULATOR PUMPS Model Comparison Chart Model Flange HP Voltage Materials of Construction GPM Max.

The Grundfos MAGNA3 series circulator pump is designed for circulating liquids in systems with variable flows where it is desirable to optimize the setting of the pump duty point, thus reducing energy costs. This pump is especially suitable for installation in existing systems where the differential pressure across the pump is too high in periods with reduced flow demand.  It is also suitable for new systems where automatic adjustment of pump head to actual flow demand is desired, without using expensive bypass valves or similar components. Furthermore, the pump is suitable for systems with hot water priority as an external signal can immediately force the pump to operate according to the maximum curve, for example in solar heating systems.  Simply install the pump and leave it on the factory setting, AUTOADAPT.  The pump will automatically analyze the heating system, find the optimum setting and then continuously adjust its operation to changes in demand saving time and effort. The MAGNA3 is the most efficient circulator available on the market today. With the lowest Energy Efficiency Index (EEI) in the world, below 0.20, you can achieve energy savings of up to 75% compared to a typical installed circulator. With the unique Autoadapt control these savings can be as much as 85% and thereby a remarkably fast return on investment.
