Abstract (en)
[origin: WO2014095291A1] The invention relates to product-lubricated multiphase pump (2, 110, 116) for pumping a hydrocarbon-containing multiphase mixture. In order to achieve good cooling and lubrication of pump elements without a lot of operating fluid and operating fluid circuits, the multiphase pump (2, 110, 116) has a separation system (40) having a first separating stage (42) for at least partial separation of at least a part of the multiphase mixture into a plurality of phase-enriched components, and a feed system (66) for feeding a fluid-enriched fluid component as a lubricant to a pump element to be lubricated.
