ALPHA1 L Circulator Pump
Brand: Grundfos Holding A/SThe ALPHA1 L is a universal replacement and upgrade circulator pump.
It can replace most old Grundfos circulators in appliances – such as boilers – and is a convenient and reliable option for replacing thousands of old inefficient pumps currently in operation.
With its compact design, simple connection to boiler signal cables (PWM) and tolerance for higher ambient temperatures, the ALPHA1 L fits seamlessly in the majority of boilers equipped with Grundfos pumps, regardless of the boiler brand.
This makes it easy to replace broken or inefficient pumps, without the need for excess spares.
Features- Clever solution: PWM signals and profiles available with return signal showing power consumption, alarm and operation status.
- Robust start-up: If the rotor is blocked, the pump automatically attempts a restart, swiftly breaking up any deposits of dirt or lime. You can also access a manual deblocking screw from the front.
- Easy use: Simple user interface and one-touch operation enables simple set-up.
