ALPHA1 GO circulation pump 25-40 180

This solution is designed for domestic central heating (C.O.) installations and operates autonomously – no manual adjustment required. The EC motor automatically analyses the system’s demand and adjusts the power, reducing energy consumption without loss of performance. No regulation is needed – it works exactly when it should, at that moment.

Quiet operation is not an extra feature but a standard: a noise level below 25 dB ensures the pump does not disturb even in small homes or rooms located close to the boiler. Installation is simple – a mounting length of 180 mm and 25 mm connections match most standard heating layouts. No adaptations or additional components are necessary.

Protections work without user intervention: dry‑run protection prevents motor damage when water is absent, and automatic air venting eliminates the need for manual air removal from the system – shortening service time and reducing failure risk.

The pump operates over a wide temperature range – from –10 °C to +110 °C – making it suitable for both modern low‑temperature installations and older high‑temperature systems. Maximum working pressure is 10 bar and the head is up to 4 m, guaranteeing stability even in larger single‑family houses with several floors.

Protection class IPX4D and class F insulation are not just technical data – they indicate that the pump can withstand moisture in a boiler room and long‑term operation under load. There are no “magical” functions here. It is a simple, robust device that does its job without noise, hassle, or the need for constant monitoring.
