Abstract
A multiphase pump for conveying a multiphase process fluid includes a pump housing, a stationary diffuser, a rotor and swirl brake. The rotor is arranged in the pump housing and is rotatable about an axial direction, the rotor including a pump shaft and an impeller fixedly mounted on the pump shaft. The stationary diffuser is arranged adjacent to and downstream of the impeller. The impeller includes a blade with the blade having a radially outer tip, and a ring surrounding the impeller and arranged at the radially outer tip of the blade. A passage is between the ring and a stationary part configured to be stationary with respect to the pump housing, the passage extending in the axial direction from an entrance to a discharge. The swirl brake is disposed at the passage, and configured and arranged to brake swirling of the process fluid passing through the passage.
