What are Submersible Pumps?

submersible pump is a centrifugal water pump designed to be fully submerged in water. A centrifugal pump refers to a pump that uses a motor to power an impeller that rotates and pushes water to the ground. For the pump to be submerged in water, the motor needs to be sealed in a waterproof compartment that keeps out water. It is then placed close to the body of the pump it powers.

Submersible pumps are inserted into a water reservoir that needs drainage or pumping out. They are used for pumping water into tanks, draining areas filled with water from floods, emptying ponds, pumping sewerage, draining swamps, and at times as pond filters. In a way, filtration pumps used in fish tanks are a type of submersible pump.

What are the Advantages of Submersible Pumps?

One great thing about submersible pumps is that they don’t make a lot of noise, since water absorbs much of the noise. You can use them in areas that require minimal noise, such as areas near schools or offices.

Another advantage is these pumps do not consume a lot of energy since they do not have to suck water. By being submerged in current water, they only need to pump water out, which makes them perfect for saving on energy.

What are the Disadvantages of Submersible Pumps?

One major disadvantage of these pumps is that they corrode over time because of being submerged in water for a long time. The corrosion might eat at the waterproof seal, letting in water into the motor compartment. That can ruin the motor, and the pump altogether.

Another disadvantage of these pumps is that the waterproof seal covering the motor makes it tough for technicians to access the motor during repairs. And even after successfully accessing the waterproof compartment, it is even tougher to store it in the original waterproof state. If not properly tightened back to an airtight state, water might leak in after repairs and ruin the motor.

Final Thoughts

Submersible water pumps are pumps that are submerged in water. They are used for pumping water from a tank or a water reservoir, or for draining water in areas such as swamps.
