Looking for experiences with garden water well pumps

the pump you found is also good in terms of performance data. However, it has almost double the power consumption (2.2kw). If you want to irrigate automatically, this will be noticeable since the pump runs for several hours per week.

Mercedes is more like Wilo ;)

No, the pump is 0.75kw, the 2.2 refers to the control box, which can handle pumps up to 2.2KW.

I did not mean to say that a 400-volt pump should be used, but only that something like this was installed here. I do not know if something like this was also available in 220 volts back then. And furthermore, I also wanted to say that a pump can last a very long time without needing constant maintenance.
