ALPHA1 L is a high-efficiency circulator pump designed for heating systems. The pump can be used as stand-alone or integrated in existing systems as replacement or in new heating systems.
The universal upgrade and replacement pump
The 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.
Fits all applications
The ALPHA1 L is flexible enough for you to use in almost any heating application and is perfect for boilers.
PWM signals and profiles available with return signal showing power consumption, alarm and operation status.
