The solar-powered water pump industry has been on a meteoric rise, especially in regions where access to the grid is challenging. For solar pump retailers, installers, and distributors, getting the installation right is more than just putting components together—it’s about ensuring system longevity, efficiency, and ROI. It’s a business-critical operation.

Understanding how to correctly install water pumps in solar-powered systems can be the defining factor between a thriving business and a failing one. Here, I lay down the guidelines you need to follow for a seamless installation process.

Intrigued enough? Let’s pump up your knowledge on this.

What Factors Should Be Considered When Using a Deep Well Pump?

The first step in installing a deep well pump is ensuring that the well is properly drilled and cleaned. According to research, the hole size of the well must be larger than the maximum size of the deep well pump. No one wants to deal with the fiasco of a pump getting stuck or not fitting properly.

Now, what about the pump installation position? The pump should be placed at a minimum depth of 1 meter below the dynamic water level. This is crucial for the pump’s efficiency and lifespan. In addition, the pump should be at least 5 meters above the bottom of the well. This reduces the risk of sediment and impurities affecting the pump.

What Should I Know About Well Sensors?

When connecting the well sensor, it’s essential to differentiate between high, medium, and low levels. For this, a 3-core 0.3 flat wire is usually sufficient for sensor wire lengths up to 100 meters. For lengths exceeding 100 meters, it’s recommended to use a shielded 3-core wire to minimize signal interference. Trust me, it’s better to invest in quality wires now than to suffer from poor performance later.

What Are the Best Practices for Fixing the Pump in a Deep Well?

To fix the pump in a deep well, you’ll need to hoist it into the well using a wire rope and clamp. Additionally, the wellhead should be fixed with a bracket. This not only ensures a stable installation but also makes future maintenance easier. Don’t skimp on this; a stable foundation is key to a long-lasting system.

Which Materials Should Be Used for Water Pipes?

For water head heights between 80-100M, PVC water pipes are generally recommended. However, for depths exceeding 100M, consider switching to steel pipes within the well. Just make sure these steel pipes are treated for rust prevention. A rusty pipe can lead to all sorts of issues, including compromised water quality and reduced pump efficiency.

What About Wiring Considerations?

The wire connecting the controller to the water pump should ideally be within 100 meters. If the wire exceeds 300 meters, it’s advisable to add a reactor and use a thicker output cable to prevent voltage drops. Electrical efficiency is not something to be taken lightly; make the right choice and protect your investment.

Important Notices to Keep in Mind

• Never start the motor without water.
• Avoid using the cable to lift the motor from the deep well.
• Make sure the pump is installed with at least 1 meter of water covering it.
• Don’t connect the pump to a wrong electrical network for more than 1 minute.
• For wells that have been inactive for a long time, ensure to remove any sand or mud water before installation.

Conclusion

Ensuring a proper installation of your solar-powered water pump system is not just a technical requirement—it’s a business imperative. By following these guidelines, you set the stage for a highly efficient and long-lasting system that will not only satisfy your customers but also boost your business’s bottom line.
