Circulation pump Grundfos ALPHA1 32-60 180, head 3.06 m, flow 2.28 m³/h, power 45kW

Circulation pump Grundfos ALPHA1 32-60 180 is a highly efficient solution for domestic and commercial heating and air conditioning systems. The model features a nominal head of 3.06 m and a maximum head of 60 dm, as well as a nominal flow rate of 2.28 m³/h, making it an ideal choice for standard heating installations with radiators, underfloor heating, and mixed systems.

The pump is designed with an electronically commutated motor (ECM), which ensures low energy consumption and long service life. Its energy efficiency index is EEI 0.20 – an indicator of exceptionally high efficiency and economy.

ALPHA1 32-60 180 is equipped with intelligent control and offers three main operating modes: constant pressure, proportional pressure, and fixed curve, with each mode providing three separate speed settings for precise adjustment according to the type of installation.

Installation is simplified thanks to the tool-free quick connector, which ensures easy electrical connection. Dry-run protection and the automatic air venting function guarantee quiet and reliable operation while protecting the system from damage.

The model features stable start-up, which reduces the risk of blockage caused by contaminants, magnetite, or limescale buildup. In case of difficulty, the motor automatically applies maximum torque to restore operation.

The ceramic shaft and bearings ensure minimal wear and extended service life, while preventing noise and vibrations.

Diagnostic symbols are located on the front panel, allowing for quick and easy identification of errors and malfunctions.
