ALPHA
The Grundfos ALPHA is the next generation of energy
efficient wet-rotor circulator pumps. By incorporating a
permanent magnet motor design, power consumption
is now reduced by a minimum of 50 %.
With the AUTO
ADAPT
feature, Grundfos ALPHA will
automatically analyze the system demands and adjust
head and or flow requirements to meet changing
heating demands.
Standard features

easy push-button hydraulic selection
seven hydraulic selection options:
– three fixed speeds
– three constant pressures
– AUTO
ADAPT
easy-to-read LED display
– flow indicator (gpm)
– power consumption (Watt)
– hydraulic selection
nut capture flange
metallurgical options
– cast iron (F or FR)
– stainless steel (F)
line cord or conduit connection options.
