Abstract: A circulation system is provided to move a coolant liquid in a coolant chamber (44) formed between a housing (40) and a motor shroud (42) of a pump (10) for a fluid being worked upon. The circulation system has a coolant impeller (54) in a coolant impeller chamber (56). The coolant impeller is driven by a drive shaft (20) that also drives a primary impeller (24) that moves the fluid being worked on. The coolant impeller is positioned along the drive shaft between the motor and the primary impeller. The coolant impeller has a wide inner portion (74) and a peripheral base disk (76) that define a radially-offset suction eye (72) and support a plurality of impeller blades (70). A seal spring (86) compressively acts on the inner portion, providing a mechanical seal.

Abstract: A compressor rotor for turbomachinery, such as a compressor, is provided. Disclosed embodiments can benefit from seal elements that may be arranged to inhibit passage onto respective hirth couplings of process fluid being processed by the compressor. A seal element may be affixed to adjacent rotor components (e.g., adjacent impeller bodies) by way of a slip or interference fit connection to one of the adjacent components and may be affixed to the other adjacent rotor component by way of a elastically flexible frustoconical inner surface of the seal element that permits the seal element to be placed in a spring-loaded condition, which generates a biasing force to circumferentially clamp onto a frustoconical outer surface of the other adjacent rotor component. This arrangement is conducive to user-friendly assembly/disassembly of the seal elements with respect to the adjacent rotor components.

Abstract: An electric submersible pump includes a pump, an electric motor that is coupled to the pump by a rotatable shaft, a seal section that is positioned between the pump and the electric motor. The seal section contains an additive and a motor oil for the electric motor. The additive includes one or more superabsorbent polymers or imidate salts to contact the motor oil and to react with a wellbore fluid from a wellbore to prevent premature failure of the electric submersible pump from the wellbore fluid contamination of the motor oil.

Abstract: Rotor structure for a turbomachine, such as a centrifugal compressor is provided. Disclosed embodiments make use of venting/sealing arrangements effective for venting a tie bolt rotor so that, for example, an incipient leakage of a process fluid can be monitored. Additionally, in operation disclosed embodiments are effective to, for example, convey to the tie bolt a pressurized sealing fluid effective for reducing the likelihood of process fluid escaping to the atmosphere.
