  • Patent number: 10514047
    Abstract: A pump (100) has an inlet (28), a first outlet (30) and a second outlet arrangement. The pump (100) is arranged so that when operated in a body of water (104), water from that body of water (104) is pumped thought the first outlet to a remote location. Additionally liquid is delivered to the second outlet system (102) which subsequently flows out from the second outlet system (102) back into the body of water (104) to create a flow of the liquid back into the body of water 104 and away from the pump (100). The liquid can be water from the body of water (104). In this instance a portion of the water at the first outlet can be diverted to the second outlet arrangement. But alternately liquid can be sourced externally from the body of water (104).

  • Publication number: 20150023822
    Abstract: Systems and methods for providing seals around the motor leads and other conductors in ESP's. In one embodiment, elastomeric boot seals are positioned within annular spaces around motor leads in an ESP motor. When the motor is filled with dielectric oil, the elastomeric material of the boot seals absorbs some of the oil and swells. High temperatures may also cause the material of the seals to expand. Retainers which are not subject to swelling are positioned around the boot seals, thereby preventing the boot seals from expanding away from the leads. The retainers thereby maintain the seal of the boot seals against the motor leads.

  • Publication number: 20150004031
    Abstract: An electrical submersible pump assembly has a rotary pump, an electrical motor, and a seal section. A drive shaft extends from the motor into the pump. A radial bearing for the shaft includes a bearing sleeve secured to the shaft for rotation. A bushing rotatably receives the bearing sleeve in sliding contact. A support member has a receptacle into which the bushing locates. The receptacle has a greater inner diameter than an outer diameter of the bushing, defining an annular gap. A bearing carrier has a bore into which the support member is secured against rotation and radial movement relative to the bearing carrier. A compliant member in the gap in engagement with the bushing and the support member prevents rotation of the bushing relative to the support member and allows limited radial movement of the bushing relative to the bearing carrier.

  • Patent number: 8911219
    Abstract: A submersible, water circulation system for enclosed tanks such as used by municipalities, fire districts, and industries. The system includes a driving unit having a shell extending along an axis with a pump supported within the shell. The shell has at least one inlet and at least one outlet and is positionable on the floor of the tank with the outlet facing upwardly. In operation, the pump continuously draws an incoming flow of water from outside of the driving unit adjacent the tank floor through the inlet of the driving unit and preferably drives all of the continuously incoming flow out through the upwardly facing outlet. The upwardly facing outlet is preferably a thin, elongated slot that creates a thin, substantially planar discharge of water therethrough that presents a very large surface area for its volume and induces water adjacent the shell to move upwardly with it.

  • Patent number: 8899941
    Abstract: A technique is provided for pumping fluid in subsea applications. A self-contained pumping module is created by mounting a pumping unit on a skid that can be lowered to a sea floor. The skid comprises a support structure designed to hold the pumping unit in a desired orientation, such as an inclined orientation with respect to a base of the skid. The self-contained nature of the pumping module facilitates deployment to a sea floor/retrieval from the sea floor to enable use of the pumping module in a variety of subsea applications with reduced complexity and cost.

  • Patent number: 8893775
    Abstract: An electric submersible pump (“ESP”) module is disclosed for producing fluids from subsea wells. The ESP module includes at least two ESPs positioned side by side and connected in parallel to discharge into a common manifold. The ESPs and manifold can be enclosed in a housing and deployed to a subsea location. At the subsea location, the ESP module can be operationally connected to an electric source, the production fluid, and to an export conduit. The production fluid from the well(s) is drawn from within the housing into one or more of the at least two ESPs which energize and discharge the production fluid into the manifold and through the export conduit to a collection point. Each of the ESPs may be selectively operated to provide the desired flow rate and/or lifting head.

  • Patent number: 8851864
    Abstract: Vibration of a rotor positioned within a stator of an electric motor of an electric submersible pump assembly is attenuated in a first embodiment by adjusting the length of the rotor to position rotor bearings supporting the rotor within the stator at locations of low amplitude vibration. In a second embodiment, hydraulic pressure is applied to a fluid chamber supporting a thrust bearing that supports the rotor. When hydraulic fluid pressure is applied, the thrust bearing and the rotor move axially. Thus, moving the rotor bearings away from areas of high amplitude vibration of the rotor. In a third embodiment, a sliding mass affixed to the motor is moved in response to vibration of the motor. Movement of the sliding mass changes the vibration profile of the motor.
