Publication number: 20160195102Abstract: A caisson for submersible pumps and method of operating a pump that is fluidly cooperative with the caisson. The pump discharge and the caisson are fluidly coupled to one another such that upon discharge of a fluid being pumped, the caisson acts as the fluid conduit, thereby removing the need for redundant riser pipes. In one form, the pump is a seawater lift pump for use with floating production storage and offloading (FPSO), offshore platforms or related structures.Type: ApplicationFiled: March 15, 2016Publication date: July 7, 2016Inventors: Mirja Koekenbier, Axel Helmut Tank-Langenau, Thomas Albers

Patent number: 9011115Abstract: A bearing assembly for use in a deepwell submersible pump, the pump and a method of pumping a geothermal fluid. The bearing assembly is constructed to include a lubricant conveying mechanism, a bearing sleeve and a multilayer bushing. The lubricant is forced between the bushing and a bearing sleeve by the lubricant conveying mechanism that cooperates with the rotation of a shaft used to connect a power-providing motor with one or more pump impellers. In this way, there exists a substantially continuous lubricant environment between the sleeve and bushing to act in a hydrodynamic fashion.Type: GrantFiled: October 30, 2013Date of Patent: April 21, 2015Assignee: Flowserve Management CompanyInventors: Behrend Goswin Schlenhoff, Axel Helmut Tank-Langenau, Thomas Albers

Patent number: 8807970Abstract: A multistage electric motor includes a plurality of motor stages connected in series, each motor stage comprising a stator, and a rotor; a plurality of cooling fluid paths, each cooling fluid path forming a recirculating loop independent of the other cooling fluid paths, each cooling fluid path in communication with the stator of one of motor stages; and a cooling fluid flowing through each cooling fluid path, the cooling fluid removing heat from the stator of each motor stage. A submersible pump including the multistage electric motor, and a method of cooling the multistage electric motor are also described.Type: GrantFiled: February 26, 2010Date of Patent: August 19, 2014Assignee: Flowserve Management CompanyInventors: Behrend Goswin Schlenhoff, Axel Helmut Tank-Langenau, Charles James Powers, Thomas Albers

Patent number: 8430649Abstract: A submersible pump system with a pump, motor and compensator assembly. In one embodiment, the compensator assembly is made up of multiple elastomeric compensators and a housing. The elastomeric compensators, which are made up of an engaging end, a floating end and a series of alternating crests and grooves, may contain motor cooling liquid. The crests and grooves extend along the compensator's longitudinal axis. The compensators possess a degree of elasticity sufficient for a width of at least one of the respective grooves to expand and contract along with the motor cooling liquid. The crests slide along an interior wall of the housing, while the floating end moves within the housing in cooperation with expansion and contraction of the width of at least one of the grooves.Type: GrantFiled: November 20, 2009Date of Patent: April 30, 2013Assignee: Flowserve Management CompanyInventors: Thomas Albers, Axel Helmut Tank-Langenau, Behrend Goswin Schlenhoff

Patent number: 8029317Abstract: A power plug system for use with a submersible pump. One embodiment comprises a male plug end, a female plug end, and a plurality of seals. The male plug end comprises a housing and a conductive sleeve. The housing receives an electrically conductive cable and conducts an electric current from the cable to the conductive sleeve. The female plug end comprises a housing, a conductive pin, and a female plug sleeve. The conductive sleeve is radially sealable within the female plug end through a plug end seal of the plurality of seals. The conductive sleeve and the conductive pin are conductively connectable. The female plug sleeve is radially sealable within a complementary plug end through a female plug sleeve seal of the plurality of seals. The conductive pin conductively connects to a conductive lead of the complementary plug end with insertion of the female plug sleeve therein.Type: GrantFiled: December 7, 2010Date of Patent: October 4, 2011Assignee: Flowserve Management CompanyInventors: Thomas Albers, Axel-Helmut Tank-Langenau, Stefan Wittenberg
