Why Do Submersible Pumps Fail

Are you the proud owner of a submersible pump and concerned about why it might fail? You’re not alone. Many people own submersible pumps, but sadly, they will always eventually fail over time. Keeping your pump running well requires understanding how it works and recognizing any warning signs that something might be wrong. In this blog post, we’ll explore what causes submersible pumps to fail and how you can prevent these issues from happening in the future. Keep reading to learn more!

What are Submersible Pumps?

Submersible pumps are electric water pumps designed to be submerged in water. They are used for various applications, from draining flooded basements to aerating garden ponds and fountains. Submersible pumps are typically more powerful and efficient than other pump types as they don’t need priming or mechanical seals due to their sealed design. They are easy to install and require low maintenance, making them ideal for various uses!

Reasons Why Submersible Pumps Fails

  • Submersible pumps can fail for various reasons, including clogging, electrical faults, overheating, wear and tear on internal components, cavitation or waterlogging.
  • Clogging is the most common cause of submersible pump failure. This occurs when debris gets stuck in the impeller or on the suction screen. An electrical fault may occur due to defective wiring or switchgear and improper power supply.
  • Overheating can happen when there are blockages in the system resulting from a lack of maintenance or a low flow rate through the pump body. 
  • Wear and tear may result from constant usage over a long period leading to thinner walls that no longer withstand pressure build-up within the pump body. Cavitation occurs when air bubbles form around an impeller, reducing its effectiveness in pumping liquid.
  • Finally, water logging happens when too much air is mixed with incoming liquid, which increases friction on moving parts resulting in damage and failure of internal components such as bearings and seals.

How to Get Rid of Submersible Pump Fails?

The best way to get rid of submersible pump failures is to inspect and maintain the pump regularly. Checking for signs of wear or damage can help prevent breakdowns before they occur. Additionally, it’s essential to ensure the pump is correctly installed and sized for maximum efficiency and that all valves, pipes, hoses and seals are in good working condition. As part of a regular maintenance routine, draining and cleaning the sump pit can also help reduce the potential for mechanical failures. Finally, having an emergency backup plan in place can be helpful in case a sudden shutdown occurs due to outside factors such as power outages or other mechanical issues.

How to Maintain Submersible Pumps?

Maintaining submersible pumps involves regular cleaning and inspections, replacing worn parts and lubricating motor bearings. It is essential to inspect the impeller, strainer basket and pump housing for any signs of corrosion or damage before proceeding with maintenance. Additionally, it is crucial to ensure that all electrical connections are secure, as loose links can lead to overheated motors. Finally, lubricate motor bearings regularly with waterproof grease for optimal performance and efficiency.

Final Words

Many factors can contribute to the failure of a submersible pump – from improper installation to terrible weather conditions. Understanding these potential causes can help prevent your pump from failing. Regular maintenance and inspections are essential to keeping your submersible pump in good working order. If you think your pump may be failing or already failing, contact a qualified technician for repair or replacement.
