The main parts of Small Diameter Submersible Geothermal Pump: Centrifugal pump/Intake/Gas Separator/Submersible motor/protector/motor lead extension/discharge.
Small Diameter Submersible Geothermal Pump is specially developed for geothermal wells and high-temperature underground water extraction projects requiring compact installation dimensions and continuous operation.
Unlike conventional submersible pumps, geothermal wells often involve challenges such as: Limited well diameter, High-temperature water circulation, Long-term continuous operation, Difficult maintenance conditions, Corrosive underground environments
Aote small diameter ESP system integrates a multi-stage centrifugal pump, gas separator, protector, and high-temperature submersible motor to provide a complete solution for deep well fluid lifting.
The standard pump diameter ranges from 3.38 inches to 8.75 inches, making it suitable for narrow geothermal wells and oilfield applications. Depending on the well conditions, customized configurations are available for different flow rates, lifting heights, and temperature requirements.
The number of pump stages is determined by the required lift. Each stage consists of a floating impeller connected to the monel-k500 drive shaft and a stationary diffuser directing the flow of the fluid. The impeller axial force is made of wear-resistant material.In order to reduce axial force, the structure of impeller and diffuser is designed by floating type. The rest axial load and pump shaft deadweight are hold by protector thrust bearing.
It's the suction port for well fluid entering the submersible centrifugal pump. Meanwhile,free gas can be separated prior to flowing into the submersible centrifugal pump,therefore relief gas effect on the pump unit.
Every section contains multiple redundant barrier chambers to enhance reliability.Barrier chambers are available in labyrinth and bag types. Shaft of protector usually uses Monel-k500 material. There are six mechanical face seals on it. Thrust bearing used in seal section has high vearing capacity. we can offer different types and series seal section to adapt individual well conditions.
The submersible Motor is the power of driving multi-stage centrifugal pump. It is two-pole three-phase squirrel cage asynchronous motor.
It mainly consists of stator, rotator and oil cycle loop system etc. Due to submersible motor is limited by well diameter and environmental temperature. Its appearance is long and thin. The max length can reach 10m. It is filled with a high strength,super dielectric oil for lubrication and thermal conductivity.
The working state of submersible motor is upright hanging. Its upper thrust bearing carries the axial force and dead weight of rotor Heat generated by the motor is transmitted to the well fluid through motor housing.
Used for extracting hot underground water for:
• District heating
• Building heating systems
• Industrial heating applications
Provides continuous hot water circulation for geothermal power plants.
Suitable for oil wells requiring compact ESP systems for fluid production.
Used in deep wells where standard submersible pumps cannot withstand temperature conditions.
Aote Tianjin Pump Co., Ltd. was established in 2004,which is a professional manufacturer in production, sales, research and development of electrical submersible pump, submersible pumps, sewage pumps and motorsin one of professional manufacturers. The company is registered as a private enterprise in Jin nan Economic Development Area, an industrial development area in Tianjin, China.
Company has strong product development capabilities, to introduce the REDA submersible electric pump technology, import of submersible motor technology developed on the basis of synchronization with the world's leading submersible pumps, submersible pumps, and derived the meet customer special requirements of various special products.
