    Abstract: In a pump system, a process fluid is directed into inlet chambers of a pump casing at an inlet pressure, and a plurality of rotors disposed inside the pump casing are rotated to pump the process fluid from the inlet chambers to an outlet chamber located between the inlet chambers, wherein the process fluid in the outlet chambers is at an outlet pressure. The process fluid is directed from the outlet chamber to a separator configured to separate particulate matter from the process fluid, and a portion of separated process fluid is directed from the separator to a gear chamber of the pump. Pump bearings are lubricated with the portion of separated process fluid from the gear chamber. Some of the portion of the separated process fluid from the pump bearing is leaked to the inlet chambers via rotor shrouds to reduce accumulation of particulate matter in the inlet chambers. A pump system and a method for operating a pump system are disclosed.

    Abstract translation: 在泵系统中，处理流体以入口压力被引导到泵壳体的入口室中，并且设置在泵壳体内部的多个转子被旋转以将过程流体从入口室泵送到位于 入口室，其中出口室中的过程流体处于出口压力。 过程流体从出口室引导到分离器，该分离器构造成将颗粒物质与过程流体分离，并且一部分分离的过程流体从分离器引导到泵的齿轮室。 泵轴承通过与齿轮室分离的工艺流体的部分进行润滑。 来自泵轴承的分离的工艺流体的一部分部分经由转子罩泄漏到入口室，以减少颗粒物质在入口室中的积聚。 公开了一种用于操作泵系统的泵系统和方法。

    Abstract: A pump system includes inlet chambers, an outlet chamber, and rotors disposed inside the inlet chambers and the outlet chamber to pump a process fluid from the inlet chambers to the outlet chamber and to direct the process fluid to a separator. A gear chamber is configured to receive a portion of the process fluid from the separator. First and second sets of pump bearings are coupled to the rotors and lubricated by the portion of the process fluid flowing from the gear chamber. A conduit is configured to direct the portion of the process fluid from the pump bearings back to the gear chamber. Some of the portion of the process fluid lubricating the pump bearings is permitted to leak to the inlet chambers. Additional process fluid is continually added to the portion of the process fluid to compensate for fluid leaking to the inlet chambers.
