  • Multiphase fluid pumping or compression device with blades of tandem design
    Patent number: 5885058
    Abstract: The invention is a device for providing one of compressing and pumping of a multiphase fluid including at least one liquid phase and at least one gaseous phase. The device includes at least one hollow casing having at least one inlet port and at least one outlet port for the fluid. At least one rotor is rotated and mounted inside the casing having an axis OX in a hub. The at least one rotor comprises at least one impeller or at least one diffuser having at least two vanes G.sub.j having a first blade A.sub.1j and a second blade A.sub.2j wherein geometric characteristics and position of at least one of the first blade A.sub.1j and at least one second blade A.sub.2j in relation to each other is determined according to at least one parameter.
