When a device or product is defective, improperly installed or maintained, or if a component of that device is worn or frayed, anyone who comes in contact with water charged with an electrical current is at risk of electric shock drowning.
What is the major disadvantage of submersible pump?
There are a few disadvantages with submersible pumps, and two have to do with the seal. The seals can become corroded with time. When that happens, water seeps into the motor, rendering it useless until it is repaired. Also, that seal makes the submersible pump a bit difficult to get into for repairs.Can submersible pump cause electric shock?

What is the difference between submersible pump and water pump?
A submersible pump is installed underwater whereas a centrifugal pump is installed on the ground. Therefore, submersible pumps are used for groundwater extraction through deep wells and centrifugal pumps are ideal for water supply and drainage applications in urban areas or for industrial purposes.
What's the difference between submersible and non submersible pump?
These terms can often be confused though the distinction is fairly obvious. Submersible pumps are complete units, including the motor, and the whole can be totally submerged whereas immersible pumps are mounted in vertical position with the motor above the liquid and the pump end extended below the liquid level.
Can submersible pump run dry?
Answer: Dry running of the pump can damage the mechanical seal and the motor. For this reason, the float switches should be arranged so that the fill level in the shaft does not fall below the minimum level required to operate the pump.
