Pulling Submersible Well Pumps A Comprehensive Guide


Submersible well pumps are vital components in modern water systems, particularly for agricultural, residential, and industrial applications. These pumps are designed to operate underwater, submerged in wells, and they offer numerous advantages, including efficiency, reliability, and the ability to deliver water from significant depths. However, pulling these pumps when maintenance or replacement is needed can be a complex task. This article will explore the intricacies of pulling submersible well pumps, including the process, tools required, and best practices.


Understanding Submersible Well Pumps


Submersible well pumps consist of a motor attached to a pump, both encased in a cylindrical housing. They work by pushing water to the surface and are known for their high efficiency, especially in deep wells. Unlike surface pumps, submersible pumps are submerged directly in the water, which prevents cavitation and allows for consistent water supply, making them a preferred choice in various settings.


The Importance of Pulling


Routine maintenance is crucial for the longevity of submersible pumps. Over time, wear and tear can lead to decreased performance, requiring the pump to be pulled from the well for inspection and service. Pulling the pump may also be necessary if it has failed, or if modifications are needed for the well system.


The Pulling Process

Pulling a submersible well pump is a meticulous process that requires careful planning and the right equipment. Here are the key steps involved


1. Preparation Before starting, ensure you have all necessary tools ready, including a hoist, slings, wrenches, and a suitable backup generator if electricity is required for the hoist. It’s important to turn off the power supply to the pump to ensure safety during the operation.

2. Remove the Well Cap The first physical step involves removing the well cap, which protects the well from contaminants and allows access to the pump.


3. Release the Torque If the pump is equipped with a check valve or joints, these must be carefully disconnected. Use appropriate wrenches to avoid damaging the pipe threads.


4. Attach the Hoist Securely attach a hoist or a pulley system to the pump, ensuring the connections are stable. It's essential to balance the weight to prevent the pump from twisting during removal.


5. Pulling the Pump Gradually lift the pump while maintaining control. It’s advisable to have an additional person assist in guiding the pump as it comes out, preventing snagging on debris or well casings.


6. Inspecting the Pump Once the pump is out, check for signs of wear, blockages, or damage. This inspection will help determine the necessary repairs or whether a replacement is warranted.


7. Reinstallation or Maintenance After inspection and necessary maintenance, the pump can be reinstalled by reversing the pulling process.


Best Practices


- Regular Maintenance Conduct routine checks to catch potential issues before they require pulling. - Documentation Keep records of all maintenance performed to track performance and anticipate future needs. - Safety First Always prioritize safety by using the correct equipment and techniques.


In conclusion, pulling submersible well pumps, although demanding, is a necessary procedure that can enhance the efficiency and longevity of your water system. With proper preparation, the right tools, and adherence to safety protocols, you can ensure that the process is performed smoothly and effectively.
