Patent ID: 6955637

Claim:
A separation device comprising: a centrifugal rotor suspended from a flexible suspension device and adapted to rotate around a vertical rotational axis, a driving device adapted for rotation of the centrifugal rotor around said rotational axis, a tubular inlet member, which is connected with the centrifugal rotor and adapted to extend downwards from the centrifugal rotor and into a body of liquid, which is to be pumped by means of the inlet member into the centrifugal rotor, a non-rotatable wall which is adapted to surround in said body of liquid at least part of the rotatable inlet member, the non-rotatable wall being suspended from the flexible suspension device for avoiding relative pendulum movements between the rotatable inlet member and the non-rotatable wall during operation of the centrifugal rotor, and a sealing device adapted to seal between the non-rotatable wall and the rotatable inlet member.
