Understanding Deep Well Submersible Pumps

Deep well submersible pumps are designed to operate underwater, drawing water from deep wells by using a multi-stage centrifugal pump. These pumps are usually composed of several key components, including:

• Pump Motor: Typically located at the bottom of the pump, it drives the impellers.


• Impellers: These are responsible for moving the water upward through the pump.


• Diffusers: They help to guide the water flow and increase pressure.


• Discharge Head: The top portion of the pump that allows water to exit the system.

Understanding how these components work together is essential for effective maintenance and troubleshooting.

Importance of Maintenance for Submersible Pumps

Regular maintenance of deep well submersible pumps is vital for several reasons:

• Efficiency: Well-maintained pumps operate at optimal efficiency, reducing energy costs.


• Longevity: Routine care can significantly extend the lifespan of your pump.


• Reliability: Preventative maintenance can prevent unexpected breakdowns that disrupt water supply.


• Quality of Water: Proper maintenance helps to ensure that the water extracted is clean and safe.

Creating a Maintenance Schedule

A structured maintenance schedule is key to keeping your deep well submersible pumps in top condition. Below are essential timeframes for various tasks:

• Monthly: Inspect the pump for unusual noise or vibrations, check the power supply, and evaluate the water quality.


• Quarterly: Clean filters and strainers, verify the pressure settings, and check electrical connections.


• Annually: Conduct a complete inspection, replace worn components, and test the motor performance.

Customizing your schedule based on usage and environmental conditions will ensure your pump receives adequate attention.

Routine Maintenance Tasks

Performing routine maintenance tasks is essential for the functionality of your deep well submersible pump. Key tasks include:

1. Inspections

Regularly inspect the pump for signs of wear, corrosion, or leaks. This includes checking the electrical components and the discharge head for any damages.

2. Cleaning Filters and Strainers

Clogged filters can reduce the pump's efficiency. Clean or replace them as necessary to maintain optimal water flow and quality.

3. Checking Electrical Connections

Ensure that all electrical connections are secure and free from corrosion. Regular checks can prevent electrical failures that may damage the pump.

4. Monitoring Performance

Keep an eye on the pump’s performance indicators, such as flow rate and pressure, to identify any drop in efficiency early.

Troubleshooting Common Issues

Despite regular maintenance, issues can arise. Here are some common problems and their solutions:

1. Pump Won’t Start

If your pump doesn't start, check the power supply, circuit breaker, and connections. It may also indicate a problem with the motor.

2. Low Water Output

Reduced water output can be caused by clogged filters, a worn impeller, or a drop in the water table. Examine and address these factors as needed.

3. Unusual Noises

Strange sounds may indicate mechanical wear or debris within the pump. Investigate and rectify any damaged components.

Best Practices for Pump Care

Implementing best practices can further ensure your deep well submersible pump remains functional:

1. Use Quality Water

Ensure that the water being drawn is free from excessive debris and contaminants. Poor water quality can lead to premature wear.

2. Protect Against Overheating

Install thermal overload protection to prevent overheating of the pump motor, which can cause significant damage.

3. Monitor Water Levels

Regularly monitor the water table levels to avoid running the pump dry, as this can lead to serious damage.

4. Professional Inspections

Schedule periodic professional inspections for a comprehensive evaluation of your pump's condition.

When to Seek Professional Servicing

While routine maintenance can be performed by most users, certain situations warrant professional help:

• Complex electrical issues


• Severe mechanical failures


• Persistent performance problems despite routine maintenance

Having a professional assess these issues can save significant time and resources in the long run.
