Noises in the pump, it can be cavitation, I suggest de-firing in operation in order to eliminate all air bubbles. It can also be suction cavitation, it is advisable to put a vacuum gauge in the suction

1, 3, 5, what part of the type number is this referring to?

[@grundfos]

Hi NES088, These numbers refer to the product categories of the CR pumps. You can read more on the website: grundfos.to/34x6P7z. I hope this answers your question. Kind regard, the Grundfos team
