Use these useful tips to observe any change in the submersible pump and schedule the appropriate services for maintenance, either by doing them yourself or leaving them in the hands of professionals.

Make regular inspections of the submersible pump

Submersible pumps often spend very large periods of time without being seen, however, there are some easy maintenance checks that can be done to ensure optimum performance and longevity.

The first thing is to monitor the pump’s output to ensure that everything works as usual. From the surface, be sure to verify that there are no water leaks, evaluate the condition of the electrical wiring and organize the valves and seals so that they are changed according to the manufacturer’s or supplier’s instructions.

It is a good idea to do some annual maintenance inspections of the pumping equipment, this will provide a record of what has been verified in each review.

Symptoms to consider in the maintenance of a submersible pump

To properly maintain a submersible pump it is necessary to be aware of some signs of failure or lower performance on a regular basis. This way the problem can be tackled before it becomes very serious.

• Less water leakage: if no water comes out it is necessary to check the circuit breaker to see if it has tripped. However, the possible causes of a decrease in the output flow may be a low level of water or liquid supply, an obstruction of sand or other materials, a restricted impeller or general wear.
• Irregular water flow: If water is sprayed on the surface, you may have a problem with cracked water pipes, or the submersible pump may have a broken check valve.
• Excessive noise: if you can hear the noise of the electric motor, stop using it and contact a specialized technician as soon as possible. If you hear the noise of the pump itself, it may be due to insufficient liquid levels (if the pump is pumping air for a part of the time), or there may be a blocked or failing component.
• Excessive heating: Overheating of a submersible water pump can sometimes indicate that there is not enough water in the well to keep it cold or that the pump is failing. If the electric motor overheats, it is important to check it to avoid more expensive repairs or replacements.
• Cloudy water or obstruction: If the liquid being pumped is unusually clogged or cloudy, there may be a problem with sediments in the system. Possible solutions may include digging a deeper well for the water pump or rinsing the pump to remove any blockage.
• Particularly high electricity bills: submersible pumps generally do not work at all times, and if this occurs, it may be a sign that the switch or pump is failing. Increased use of electricity could also indicate a system blockage or impeller failure.

If you take into account these symptoms of malfunction and perform a proper submersible pump maintenance, you can use your equipment for many years.

The submersible pump is placed in the liquid, usually water, and then presses it to the surface. The submersible pump motor converts the kinetic energy into centrifugal energy and finally into pressure energy, which lifts the water out of the well.

As these pump types are very deep dipping and very easy to install, they can be used to drain ponds or pump water from deep wells.

Submersible pump operation

Submersible pumps are inserted into the liquid to be pumped so that they never have to be sucked in, as they are already immersed in the liquid. This is one of their great advantages.

Another great advantage of submersible water pumps is that the pressure of the liquid itself pushes it directly into the pump, so a lot of energy can be saved.

The main characteristic of submersible pumps is that all their components are submerged in some liquid. They are covered by a sealed body that prevents corrosion and oxidation of the internal components.

Different types of submersible pumps

There is a wide range of submersible pumps that can be perfectly adapted to pump different types of liquids, with or without solids and at different depths. Therefore, the most important thing when choosing a submersible pump is to know what type of installation it will be used for.

Single-stage submersible pumps are often used in domestic installations such as aquarium filters, sewage pumping or drainage.

On the other hand, we have multi-stage submersible pumps that are ideal for pumping underground liquids such as wells or oil fields. This type of pump can handle drinking water as well as heavier liquids such as sewage or corrosive liquids.

It is very important not to use this type of pump outside the fluid; the motor may overheat. Submersible pumps are specially designed to always work under water.

The only drawback we notice with this type of pump is that over time corrosion can occur in the elements that clog the engine. Therefore, it is very important to maintain the pump and all its components correctly.
