Claim:
1. A helical rotor of a progressing cavity pump, said progressing cavity pump pumping a multiphase fluid in a fluid reserve, said helical rotor comprising at least one mixer for homogenizing said multiphase fluid located in said fluid reserve, said helical rotor further comprising: a first outer end face coupled to a drive shaft, a second free outer end face opposite to said first outer end face, and a helical outer face connecting said first outer end face to said second outer end face, and in which said mixer comprises an inner channel having at least one fluid ejection outlet located on the second outer end face, said inner channel adapted to eject a portion of said pumped multiphase fluid into said fluid reserve to homogenize the multiphase fluid located in said fluid reserve, wherein said inner channel has at least one fluid inlet located on said helical outer face, and wherein said fluid ejection outlet is fitted with a restrictor that accelerates the ejection speed of said ejected portion of said fluid.
