    • A centrifugal pump for abrasive fluid. The pump may include a bearing housing mounted to a tank containing an abrasive fluid. The bearing housing may house wear-susceptible components in a manner distancing and isolating the components from the fluid. A shaft may be coupled to the bearing housing and disposed through the tank to an impeller for dispensing the abrasive fluid beyond the centrifugal pump. Additionally the impeller itself may be housed within an impeller housing that is mechanically coupled to the bearing housing in order to enhance dimensional stability therebetween. Such a centrifugal pump may be coupled to other pumps such as higher pressure positive displacement pumps. In these circumstances the centrifugal pump may be used to facilitate the mixing of the abrasive fluid and provide a degree of pressurization thereto in advance of the fluid's use at an operation site. For example, where the fluid is a cement slurry, a triplex pump may be coupled to such a centrifugal pump for use in a cementing application at an oilfield.
    • 磨料液离心泵。 泵可以包括安装到包含磨料流体的罐的轴承壳体。 轴承座可以以远离流体的方式将部件与流体隔离的方式容纳耐磨损部件。 轴可以联接到轴承壳体并且通过罐布置到叶轮以将磨料流体分配到离心泵之外。 此外,叶轮本身可以容纳在机械地联接到轴承壳体的叶轮壳体内,以便增强它们之间的尺寸稳定性。 这种离心泵可以联接到其它泵,例如较高压力的容积式泵。 在这些情况下,可以使用离心泵来促进磨料流体的混合,并在流体在操作部位的使用之前提供一定程度的加压。 例如,在流体是水泥浆的情况下,三重泵可以联接到这种离心泵,用于在油田的固井应用中。
