Abstract
A multiphase pump for conveying a multiphase process fluid includes a pump housing, a rotor and a radial bearing. The rotor is arranged in the pump housing and is configured to rotate about an axial direction. The radial bearing has a support carrier and a support structure to support the rotor with respect to a radial direction. The rotor includes a pump shaft and an impeller fixedly mounted on the pump shaft to convey the process fluid from a pump inlet to a pump outlet. A squeeze film damper is provided to reduce vibrations of the rotor, the squeeze film damper arranged around the support structure of the radial bearing, and having an radially outer surface. A damping gap is arranged between the support structure of the radial bearing and the radially outer surface of the squeeze film damper. The damping gap is configured to receive a damping fluid.
