The problem was that this pump does not have a brand name, and also can not be bought commercially.
As indication one had only the model number AA 190 A, the output of 200 l / h consumption of 2 watts, and all GS certified - quite difficult because CONSULT AN APPROPRIATE replacement to create.
On top of that the pump has guide rails which should fit.
Had this been lucky - it is exactly the identical pump been my - luck.
Have a hexagon Nano basin with 20L, as they exist for 60 on eBay, as I said markless - probably from China.
Bin otherwise with filter performance, and was thus particularly easy maintenance due to very satisfied.
So as I said, the pump fits in mir.Auch the guide rails, and runs perfectly quiet.
