A submersible pump is designed to shift any fluid from one place to another, by rotating an impeller. This pump is submerged within that liquid substance and its impeller is driven by a motor that is sealed within the pump body. The motor converts kinetic energy to the pressure exerted on the blades of the impeller, to push out water. Therefore, a submersible pump is considered an efficient device for draining out bulk quantities of water from all flooded areas during heavy rains.
A Few Merits of Using a Submersible Pump in Waterlogged Places
Many advantages are noticed in submersible pumps, which are widely used in all places during monsoon season. This type of pump is preferred over the traditional pumps that pull out water, due to the easiness of operating a submersible pump. It is also safe for users and living beings moving around in that waterlogged space, as there is no risk of electrical shock injuries caused by this pump.
Least Energy Needed
A submersible pump uses the kinetic energy generated by moving the blades of the impeller. It converts this energy into high pressure that can easily push out water from a place. Hence, this pump does not need extra energy to drive out bulk volumes of water in heavily waterlogged places.
Easily Push Out Water
The impeller of a submersible pump rotates continuously and pushes out the surrounding water with its diffuser blades. These blades are designed in a specific shape to drive out water with a greater velocity than that of the surrounding water. This operation is much faster and more effective, which can be seen by the decrease in the water level of a waterlogged place very quickly.
More Powerful Operation
Submersible pumps are provided with highly powerful motors, which are useful in handling situations in heavily flooded areas during natural disasters. So, these pumps are found more reliable and effective in draining out water more quickly than pedestal pumps that pull out water and take a much longer time. Since the motor is totally concealed in the pump body, there is no risk of damage while the pump is submerged in water.
Can Drain Out Huge Volumes of Water
A submersible pump is capable of removing large quantities of accumulated rainwater. So, it functions accurately even in places that are completely submerged in water during floods caused by heavy rains or water released from nearby dams.
Function Silently
Usually, the motors of pumps create loud noises that disturb the surrounding environment. However, submersible pumps do not make any sound while operating, as they function entirely within water. Any sound wave created by the motor of a submersible pump is absorbed immediately by the surrounding water. So, this pump does not cause sound pollution while draining out water from waterlogged areas.
Very Low Chance of Damage
Most pumps can be damaged due to cavitation, which occurs when the fluid pressure is lower than the pressure exerted by its vapour in the form of bubbles. The operating pump system can be damaged due to the presence of too many bubbles that form while draining out water. However, submersible pumps are mostly free from this problem, as these pumps are placed below the water level. So, these pumps are saved from such damages caused by cavitation, ensuring greater longevity of the devices.
Push Out Solid Particles Too
The blades of a submersible pump can easily push out solid particles present in the accumulated water of a place. Unlike other pumps, the blades of this pump are not blocked due to these solid materials. Hence, the operation of this pump is not interrupted by the clogging of blades, as seen in the case of other pumps. Moreover, waste solids are not left behind after the water is drained out.
Least Maintenance Required
As a submersible pump operates within the water, its motor is immediately cooled by the surrounding coldness of the water. So, there is no risk of overheating the pump even if it continues working for several hours. Operators do not need to check the temperature of the motor frequently and worry about the strain exerted on the pump while running a submersible pump. Mechanical issues are very rarely found in submersible pumps, minimizing the repair of these devices.
Environment-Friendly Action
Submersible pumps save the environment and localities from severe floods, which is a major problem during monsoon. Soil erosion can be prevented by draining out excess rainwater quickly; otherwise, the quality of cultivatable lands can be damaged. Moreover, these pumps require the least energy for operation and work silently, as both these factors contribute to the betterment of the environment.
Helpful for Health
Accumulated rainwater can become the birthplace of many germs and mosquitoes, which are harmful to the health of humans and other creatures. Roots of trees may rot due to the accumulation of water for a long time, resulting in their death. Submersible pumps save all living creatures from these harms, by draining out water quickly from waterlogged areas.
Saves Flooring Space
A submersible pump is designed in a compact size, which can fit anywhere without consuming much space. Hence, no separate pumping station is needed to run this pump. It can be used in all small areas despite space constraints. Moreover, it can be easily carried to different residential and commercial places to drain out water during monsoon.
Easy Installation and Operation
Since a submersible pump is not made of parts that need to be assembled or disassembled for operation, it can be installed very easily anywhere it is required to function. It is also simple to retrieve this pump when all the accumulated water is pushed out from a site. No special training is required for installing, operating, and monitoring the function of a submersible pump.
Conclusion
Submersible pumps are highly useful in draining out water from all flooded areas. Therefore, these pumps are the first choice of local civic bodies, in freeing low-lying areas from accumulated rainwater quickly. These pumps are also preferred to dry up waterlogged agricultural lands and industrial units. This disaster management tool is useful in saving construction sites from the damage done by water logging. Due to the versatile nature of a submersible pump, it can be used to clear out filled sewage tanks too.
