Abstract
A multiphase pump for pumping a multiphase mixture containing hydrocarbon includes a separation system and a supply system. The separation system has a first separation stage configured to at least partly separate at least one portion of the multiphase mixture into a plurality of phase-enriched components, the first separating stage including an impeller attached to a pump shaft of the multiphase pump and being having an inlet side formed by a seal. The supply system is configured to supply a liquid-enriched liquid component as a lubricant to a pump element to be lubricated.
