I believe the Pump from my "AMS 420 mm,Copper Radiator, D5 Pumpe mit USB/aquabus (Article Number 33064)" is somehow broken as it makes a very loud vibrating noise.
I'm going to take the Radiator out and take a better look at it, the question is, can this be replaced with a new pump (Article 41093) ? Or is the pump somehow soldered to the Radiator ?
