Grundfos Alpha2 Go 25-60 180

The referent in hydraulic circulation and balanced. Regulated circulator pump for heating and high efficiency residential air conditioning.

Technical Study: AutoAdapt regulation and seasonal energy efficiency

In fluid engineering applied to building, precise flow control and static pressure is essential to avoid cavitation noises on thermostatic valves and energy overstops. The circulating pump Grundfos Alpha2 Go 25-60 180 incorporates the patented AutoAdapt technology, which continuously monitors the dynamics of the hydraulic network. When detecting the opening or closures of the heating branches, internal electronics adjusts the proportional or constant pressure curve instantaneously. Its synchronous motor controlled by frequency converter drastically reduces consumption compared to old fixed speed pumps. Thanks to this, the device decreases the effort of the distribution system and provides a direct benefit in reducing the thermal load losses of the installation.

📈 Maximum adaptability: designed to integrate seamlessly in boilers, radiant soil systems and air stopermia circuits.

Intelligent automatic adjustment, mechanical robustness and residential adaptability

The circulating pump Grundfos Alpha2 Go 25-60 180 Redefines the standards of the hydraulic distribution by presenting a gray casting body with electrophoresis treatment that guarantees total immunity against oxidation and internal wear by sediments. Its length between 180 mm mouths is the market standard, facilitating a direct replacement of old circulators without the need to modify the installation collector or perform complex reforms in the technical room pipes.

The differential element of the ALPHA2 series lies in its intuitive control panel and its technical communication capacity. Since its front screen, the instant energy consumption expressed in watts and the approximate flow of the system are displayed. Installers can be manually selected between three proportional pressure curves (for traditional radiators), three constant pressure curves (optimal for radiant soil circuits) or three fixed speeds, in addition to the autoadpt intelligent logic that is self-regulating Continuous way according to the habits of use of housing.

Thanks to its design with wet rotor, the installation fluid itself lubricates the high-strength ceramic bearings, achieving a completely silent operation that cancels any vibration transmission through the dwelling marks. The circulator includes a fast connection alpha plug that substantially simplifies the initial electrical wiring and serial thermal insulation housings to drastically minimize residual heat losses towards the environment.

Hydraulic assembly criteria and integration in heating networks

To ensure the ideal hydraulic flow and prevent premature wear on the engine of the Grundfos Alpha2 Go 25-60 180, the pump must be installed with the axis of the motor strictly located horizontally. The arrows recorded in the smelting body indicate the mandatory direction of the water flow. It is recommended to place cutting valves on both sides of the thread G 1 1/2 to facilitate circuit cleaning tasks or future technical inspections without the need to empty the entire network of pipe pipes.

Before carrying out the first start-up, it is essential to perform a complete purge of the accumulated air in the system through the automatic deaeration function integrated into the pump interface itself. Since the model handles advanced electronic logics, it is highly recommended to verify that the filling water is free of metal sediments by installing a magnetic gauge in the return of heating, preventing the particles attracted by The magnet rotor affects the free rotation of the impeller.
