Introduction

This tutorial will guide you through the process of disassembling the delivery head of a 1 KW LOWARA submersible pump designed for artesian wells. Understanding how to properly take apart this pump is essential for maintenance or repair tasks. The left-hand threading of the pump may require specific techniques to prevent damage.

Step 1: Gather Your Tools

Before you start disassembling the pump, make sure you have the following tools ready:

  • Adjustable wrench
  • Screwdriver set (flathead and Phillips)
  • Pliers
  • Safety goggles
  • Gloves

Practical Tip: Wearing safety goggles and gloves will protect you from sharp edges and any debris that may come loose during disassembly.

Step 2: Disconnect the Pump

  1. Turn off the power supply to the pump to ensure safety during the disassembly process.
  2. Remove any electrical connections and take note of where each wire connects for reassembly later.
  3. Disconnect the pump from the well or the water source by carefully unscrewing any fittings.

Step 3: Prepare for Disassembly

  • Place the pump on a stable work surface to prevent it from rolling or moving during disassembly.
  • Inspect the pump for any visible signs of wear or damage that may affect the disassembly process.

Step 4: Remove the Delivery Head

  1. Identify the left-hand thread on the delivery head. Remember, this means you need to turn it clockwise to loosen.
  2. Use the adjustable wrench to grip the delivery head securely.
  3. Twist gently in a clockwise motion until it loosens. If it's stuck, apply a penetrating oil and let it sit for a few minutes before attempting again.

Common Pitfall: Forcing the delivery head can lead to damage. If it doesn’t budge, ensure it's not cross-threaded or damaged.

Step 5: Disassemble the Components

  • Once the delivery head is removed, carefully take out any internal components, noting their arrangement.
  • Use the screwdriver to remove any screws holding the internal parts in place.

Step 6: Inspect and Clean

  • Check all parts for wear and tear, especially seals and gaskets. Replace any damaged components before reassembly.
  • Clean all parts using a suitable cleaning solution to remove dirt and debris.

Step 7: Reassemble the Pump

  1. Reinsert all components in the reverse order of disassembly.
  2. Make sure the left-hand threads are aligned properly before tightening the delivery head by turning it counterclockwise.
  3. Reconnect the electrical wires as per your notes from the disassembly step.

Conclusion

Disassembling a LOWARA submersible pump requires careful attention to detail, especially regarding the left-hand threading. By following these steps, you can effectively maintain or repair your pump. Remember to double-check all connections during reassembly and ensure that any worn parts are replaced. If you're uncertain at any step, consider consulting a professional.
