Seal wall penetration

I have received a pipe from the basement to the pool technology room to get a water connection outside. This way I now have a connection from the basement to the outside. The required lines are already laid, but how can I seal the whole thing now?? I have attached a picture. Can anyone give me a good tip? Thanks in advance

Are both rooms part of the building, or is the room by the pool located elsewhere on the property?

That is just a small technical shaft by the pool where the pump and the filter are. So not inside the house but outside.

With a ring groove seal. Since the cables are already in place, it must be a split ring groove seal.
