    • A pump for pumping a multiphase fluid includes a housing (28) and a rotor (38) with an outer surface. A plurality of inducer vanes (42) are attached to the rotor hub, each having a leading edge (48) and a trailing edge (52) where the leading edge of one inducer vane overlaps the trailing edge of an adjacent inducer vane by a first overlap angle. A plurality of impeller vanes(44) are also attached to the hub. The impeller vanes each have a leading edge (54) and a trailing edge (58) where the leading edge of one impeller vane overlaps the trailing edge of an adjacent impeller vane by a second overlap angle larger than the first overlap angle. The pump includes a rotor flow channel extending between the hub outer surface and the housing inner surface. The rotor flow channel has an inlet area and an outlet area, whereby the outlet area is smaller than the inlet area.
    • 用于泵送多相流体的泵包括壳体(28)和具有外表面的转子(38)。 多个导流叶片(42)附接到转子轮毂上,每个导轮叶片具有前缘(48)和后缘(52),其中一个导流叶片的前缘与相邻导流叶片的后缘重叠, 重叠角度 多个叶轮叶片(44)也附接到轮毂。 叶轮叶片各自具有前缘(54)和后缘(58),其中一个叶轮叶片的前缘与相邻叶轮叶片的后缘重叠大于第一重叠角的第二重叠角。 泵包括在轮毂外表面和壳体内表面之间延伸的转子流动通道。 转子流动通道具有入口区域和出口区域,由此出口面积小于入口区域。
