摘要： A multiphase pump for conveying a multiphase process fluid from a low pressure side to a high pressure side includes an outer housing, a casing, the casing having a pump inlet and a pump outlet for the process fluid, and a pump rotor capable of rotating about an axial direction arranged within the casing, and configured to convey the process fluid from the pump inlet to the pump outlet. The casing includes a plurality of stage segments, and the plurality of stage segments include an individual stage-segment, a low pressure segment arranged at the pump inlet and a high pressure segment arranged at the pump outlet, the individual stage-segment arranged between the high pressure segment and the low pressure segment, and the plurality of stage segments being held together by a sealing support structure, the casing being arranged within the outer housing.

摘要： A process fluid lubricated pump includes a pump having a pump shaft extending from a drive end to a non-drive end to rotate about an axial direction, a first pump section having a first set of impellers fixedly mounted on the pump shaft to increase the pressure of the process fluid, a drive to exert a torque on the drive end of the pump shaft to drive the rotation of the pump shaft, a first balance drum fixedly connected to the pump shaft between the pump and the drive end of the pump shaft, the first balance drum defining a first front side facing the pump and a first back side, and a second balance drum fixedly connected to the pump shaft between the pump and the non-drive end of the pump shaft, the second balance drum defining a second front side facing the pump and a second back side.
