Pulling a Submersible Well Pump A Comprehensive Guide


Submersible well pumps are essential devices used in various applications, including residential, agricultural, and industrial settings. They are designed to be submerged underwater, where they draw water from the well and push it to the surface. Over time, these pumps can fail due to wear and tear, power issues, or mechanical failures, necessitating their removal for repair or replacement. Pulling a submersible well pump is a task that can be daunting for many, but with the right tools and knowledge, it can be accomplished efficiently.


Understanding the Components


Before embarking on the task of pulling a submersible well pump, it is vital to understand its components. A typical submersible pump consists of a motor, impellers, and a discharge head. The motor drives the impellers, which draw water into the pump and push it out through the discharge head. The pump is connected to electrical wiring and piping, both of which need to be handled carefully during removal.


Safety Precautions


Safety should always be the top priority when working with submersible well pumps. Ensure the power to the pump is turned off at the circuit breaker before beginning any work. Wear appropriate personal protective equipment (PPE), including gloves and safety goggles, to protect yourself from potential hazards. If the well is deeply submerged, consider using a harness or safety line to prevent falls.


Tools Required


To successfully pull a submersible well pump, you will need several tools


1. Wrenches For loosening and removing bolts and fittings. 2. Piping Cutter To cleanly cut any pipes connected to the pump. 3. Hoisting Equipment A rope, chain, or a well casing puller can assist in lifting the pump out. 4. Bucket or Tarp For safely lowering the pump once it is disconnected.


Steps to Pull the Pump

1. Turn Off Power As mentioned earlier, ensure the power to the pump is shut off.

2. Disconnect Electrical Wiring Carefully remove the electrical connections to the pump, taking note of how they are configured for reassembly.


3. Remove the Piping Use a wrench to disconnect the piping connected to the discharge head. This may involve cutting the pipe if it is rigidly fixed.


4. Prepare for Lifting Make sure you have a secure grip on the pump. Tie a strong rope or chain around the pump’s body specifically designed for hauling.


5. Begin Hoisting Gradually pull the pump upward. Make sure to maintain an even tension to avoid any sudden jerks that could damage the pump or the casing.


6. Clear the Well Casing As the pump nears the top of the well, be prepared to guide it out of the casing, ensuring that it does not get stuck.


7. Inspect and Maintain Once removed, inspect the pump for any signs of damage or wear. This is the perfect opportunity to perform maintenance, replace parts, and address any issues before reinstallation.


Reinstallation or Replacement


After pulling the pump and performing necessary repairs, the process can be reversed for reinstallation. Ensure all connections are secure and test the pump before finalizing the installation.


Conclusion


Pulling a submersible well pump can be a straightforward process if done methodically and safely. Understanding your equipment, maintaining safety, and utilizing the right tools will make the task manageable. Whether you are performing maintenance or installing a new unit, taking the time to do this correctly will ensure the longevity and efficiency of your water supply system. Always consider consulting a professional if you are unsure at any stage of the process.
