Grundfos ALPHA2 pumps with a venting chamber make it easier to vent the heating system directly at the pump, which is especially useful in installations where air repeatedly builds up in the system.
Like the other ALPHA2 models, they feature electronic output control, which reduces electricity consumption compared with classic pumps.
Frequently asked questions
- When is a pump with a venting chamber worth it? In systems where air repeatedly appears in the pipework and standard venting is not enough.
- How is the pump vented? The chamber has its own vent valve, through which air is simply released without having to vent the whole system.
- What is the installation length of these pumps? Models with a length of 180 mm are available – before ordering, we recommend checking the length of the original pump.
