Multiphase twin screw pumps are investigated experimentally and theoretically. A test facility with two screw pumps that can be continuously operated with water, oil and air mixtures is used to measure the delivering characteristics and the influence of recirculation on pump performance. Unsteady flow regimes like slug flow often occur in natural oil and gas processing. Therefore the operational behavior of the multiphase pumps is investigated for this case. In the development of new oil fields multiphase pumps are installed not only individually but also in pipeline networks. Serial operation of two srew pumps is investigated for steady and unsteady flow conditions. In addition to experiments a model to calculate the volumetric efficiency of the pumps is presented. The calculated results are compared to measured ones.
