The Grundfos ALPHA will change the way you view circulators. With its permanent magnet motor design, this energy efficient circulator reduces power consumption by 50% or more. The unique patented AUTOADAPT™ feature controls pump performance automatically within defined performance range, ensuring lowest possible energy consumption without sacrificing comfort.
Flow Range: 0 to 21 GPM
Head Range: 0 to 19 Feet
Min. Fluid Temperature: 36°F (2°C)
Max. Fluid Temperature: 230°F (110°C)
Max. Working Pressure: 150 PSI
The super-effective AUTOADAPT function
automatically adapts the pump to changes in demand and figures out the
optimal performance. This means end users can have the best possible
comfort combined with minimum energy consumption. AUTOADAPT works in
virtually all systems.
AUTOADAPT software recognizes changes in system
demands, i.e…valves opening and closing. By monitoring the motor
current vs. pump hydraulic relationships, motor speeds are adjusted
automatically to reflect changing head-flow requirements. Ensuring
maximum energy savings and comfort level.
