Review on Lifting pump Eheim Compact ON 3000 (3000 l/h) by Aneta Postek ᠌

In the old "Aqua medic eco runner 2700" it was necessary to replace the impeller, but unfortunately this part was not available in 2022, and buying from abroad will cost 45€ + shipping. I decided to buy a pump here, the choice fell on the Eheim CompactON 3000. The pump is used in a submerged state, it makes mechanical noise during operation, lubricating the pin does not help at all. Sounds like the impeller is hitting the hull somewhere. I rebuilt the pump several times but there is no change. It is very likely that the pin seats are not symmetrical and this causes the magnet to beat and hence the low-frequency hum. Absolutely unacceptable quality for this price!
