 Baker Hughes Geothermal - Downhole Pumps

Downhole Pumps

Centrilift supplies high efficiency environmentally friendly equipment for municipalities, high horsepower slimline motors for mining, and high temperature motors with specialized pumps for the geothermal market. A high-pressure horizontal pump has been designed to reduce downtime and repair costs for the industrial market.

Centrilift is a leading developer of technology for electrical submersible pumping (ESP) systems, variable speed drives and ESP cabling systems. Centrilift products include a full line of armored cable for hostile gas and temperature environments up to 400° F (205° C).

Products include:

  • Electrical submersible pumps, seals and motors

  • Electrospeed® variable speed control systems

  • ESP monitoring, control and shut-down systems

  • Vortex motor controller and information display units

  • Armored power cables and accessories for ESP applications

Model 562 motor powering Centrilift pumps features UltraCap

The 562 motor powering Centrilift pumps features epoxy insulation and encapsulation of internal components for high horsepower ratings and longer service life at high temperatures. Encapsulation of internal windings improves thermal conductivity for better heat dissipation, obtaining reliable operation in temperatures to 300°F (149°C).

Geothermal Power Plants
Steamboat II and III (just south of Reno, NV) comprise one of the largest binary geothermal power plants in the world. In just one year of operation:

  • Production of geothermal fluids at the facility has jumped 20 percent in each of the wells employing Centrilift’s electrical submersible pumps (ESPs)

  • Lessened the ecological impact of the operation to the surrounding area

  • Offer better productivity and have a much lower impact on the environment

  • Provide approximately 10 percent of Reno’s electricity, producing 2,500 gallons per minute of 320°F geothermal fluid

Additional Information

  • Centrilift Geothermal Development
  • High temperature Centrilift pump designs were developed using a geothermal well test program that included a number of applications in wells with temperatures to 364°F (184°C). The Magma Power Project at Fish Lake, Nevada, a joint effort by Centrilift and a production company, determined peak productivity of several wells in the field and demonstrated the reliability of Centrilift ESPs in a geothermal environment. Equipment used in these tests included 660 hp motors with 800 kVA variable speed drives. The systems were designed to produce up to 1,500 GPM from approximately 1,300 ft. The trials included thermal cycles to test effects on the equipment. Diameter seal and bearing material designs and thermal expansion criteria of current production models were developed on the basis of these test results.
