The comprehensive guide to installing and operating submersible pumps?

submersible pump It is a centrifugal pump equipped with an electric motor that operates underwater. Submersible pumps improve motor performance and operate with high efficiency even underwater and at great depths.

The submersible pump allows its users to do without the drive shaft and the entire turbine pump chamber.

A submersible pump consists of the pump and an electric motor together, in addition to pumping pipes, cables and electrical wiring that will be submerged underwater.

• How are submersible pumps installed and operated?

Submersible pumps are easy to install and remove. Follow these steps.

1. Lower the pump and motor assembly below the water level in the tank or well. Note that you must determine the depth to which you will lower the pump and motor before proceeding. Based on the required depth, you will add the pipe fittings.

2. Take all necessary precautions to avoid any damage that may occur to the sheath surrounding the electrical cable as a result of its collision or friction with the well sheathing pipes or pipes located in the wellhead.

3. Connect the electrical cable to the pumping pipes and secure the pumping line firmly. Make a cable connection to the pipes every two meters.

4. Place pipe clamps on the wellhead and equip the pumping pipe with a valve so that you can control the pipe.

5. You don't need a pump house since both the pump and motor are inside the well. However, there must be a completely secure and waterproof box next to the well for the electrical control panel (on/off switch and electricity meter).

6. Open the control valve slightly and turn on the pump.

7. When starting the pump, you must carefully check the water to ensure it is completely free of sand, mud, or any other impurities. A common mistake is immediately stopping the pump if you notice any sand, mud, or impurities in the pumped water. This can lead to the accumulation of sand, mud, or other impurities in the pump and on the valve, potentially causing the pump to malfunction permanently.

The ideal solution is to leave the control valve partially closed while pumping continues. After a while, you will notice a change in the pumped water; it will become cleaner. Increase the opening of the control valve and monitor the water. After some time, the water will be completely free of impurities, and the pump will operate efficiently without any sediment or sand inside. The principle is that the pump can be fully controlled from the control valve opening to reduce impurities and purify the water.

8. When you find that the pumped water is completely clear, turn off the pump. You have now adjusted all the settings.

One of the advantages of submersible pumps is that they may require no maintenance at all. It is recommended to have the pump inspected every two years to ensure it is functioning efficiently and that all its parts are in perfect working order. If a malfunction is detected, the pump will need to be removed from the well and the necessary repairs performed. Always check whether the pump is still under warranty.

Your choice of pump should be based on the desired water flow rate and the well depth. Note that the deeper the well, the lower the pump's flow rate. Furthermore, no single pump has a fixed flow rate.

The electrical panel next to the pump must be properly aligned, and the power supply cable selected. Ideally, a qualified electrician should perform these steps to ensure the correct current supply to the pump is properly adjusted to prevent the motor windings from burning out and the entire pump motor from failing.

The first step you can do yourself is lowering the pump into the well. For the remaining steps, an electrician should be present to ensure everything is working correctly.
