Custom Oil Immersed Submersible Electric Pump Manufacturers

The oil-immersed submersible electric pump is an electric drainage and irrigation equipment that integrates a water pump and a three-phase asynchronous motor. It uses oil as a medium for cooling and insulation, and can maintain stable operation under harsh working conditions. The characteristics of this electric pump are that the motor and the pump body are integrated into one, and the oil is used to conduct heat, improve the cooling effect, reduce the temperature rise of the motor, and increase the overload capacity. At the same time, the oil can also ensure the lubrication and cooling of the bearings and extend the life of the bearings. The main features include small size, strong practicality, good cooling effect, and long service life. It has a compact structure, is light and easy to move, has low noise, and is suitable for water supply and drainage needs in various occasions. In addition, the oil-immersed submersible electric pump also has double-end sealing and electrical protection functions, a reasonable design, and excellent performance. It is widely used in agricultural irrigation and drainage, garden sprinkler irrigation, fountain water supply, well water extraction, water tower water delivery, urban constructio,n and water use in industrial and mining enterprises. They are one of the indispensable key equipment in modern industry, especially suitable for use in mining, water conservancy, municipal administration, and other fields.

Selection Guide: How to Choose the Right Oil Immersed Submersible Electric Pump Based on Well Depth, Flow Rate, and Head

Choosing the right Oil Immersed Submersible Electric Pump is key to ensuring an efficient and stable pumping system. When selecting a pump, you need to comprehensively consider three core parameters: well depth, flow rate, and head. Based on the professional experience of Tefusen (Guangde) Intelligent Technology Co., Ltd., we will provide a detailed breakdown of each step.

1. Determine the Well Depth (Installation Depth)

The well depth is the primary consideration for selecting a submersible electric pump. It directly determines the length of the pump's cable and its overall design.

  • Measure the Actual Depth: You need to accurately measure the actual depth of the water well, which includes the static water level (the water level when no pump is operating) and the dynamic water level (the lowest water level when the pump is running).
  • Safety Margin: Considering that the water level will drop when the pump is working, it is recommended to install the pump below the dynamic water level and reserve a certain safety margin. This ensures the pump body remains submerged in water for proper cooling. Our oil-immersed electric motors, backed by over 30 years of technological expertise, are designed to ensure stable heat dissipation during long-term underwater operation, performing reliably even in deep wells.

2. Calculate the Required Flow Rate

The flow rate, which is the volume of water you need to pump from the well per unit of time, is a crucial factor in determining the pump model size.

  • Domestic Use: For households or small farms, you can estimate the flow rate based on the number of people and equipment.
  • Agricultural Irrigation: You need to calculate the required flow rate based on the irrigated area, crop type, and irrigation cycle.
  • Industrial Applications: Requires precise calculation based on the water needs of the production line.

As a comprehensive pump company with over 20 series of products, Tefusen has a wide range of submersible pumps with various flow rate specifications. Our technical team can provide customized flow solutions based on your specific needs, ensuring efficient use of water resources.

3. Determine the Required Head

The head is the pump's ability to lift water from the well to a specified height. It is one of the most important technical parameters for pump selection.

Components of Total Head:

  • Vertical Head (Static Head): The vertical height difference between the pump's outlet and the final point of use.
  • Horizontal Head (Friction Loss): The resistance loss generated as water moves through the pipeline. The length of the pipe, elbows, valves, and pipe diameter will all affect this loss.

Calculation Formula:

Total Head = Vertical Head + Horizontal Head

To ensure the pump can overcome all resistance, it is recommended to add a 10%-20% margin to the calculated total head. Tefusen (Guangde) Intelligent Technology Co., Ltd. has a professional technical and engineering team of 30 people who will accurately calculate and match the most suitable head for you, preventing issues like low water output or no output due to insufficient head, thus ensuring the best return on your investment.

Choosing the right oil-immersed submersible electric pump requires you to accurately grasp the three core data points: well depth, flow rate, and head. As a company that has been deeply involved in the pump industry for over 30 years, Tefusen (Guangde) Intelligent Technology Co., Ltd. can provide you with a full range of solutions, from product design and production to sales, thanks to our extensive experience and comprehensive product line. Our products, including submersible pumps, deep well pumps, and many other series, can meet selection needs for various operating conditions. If you have any questions during the selection process, please feel free to contact our professional team, and we will provide you with the most suitable selection plan.
