Electric submersible pumps are one of the best water pumps anybody in need of a pump should consider. Electric submersible pumps are well known to collect water from deep sources like wells. This article will elaborate further on this specific type of water pump. Its advantages and disadvantages and how the pump works.
This is a device connected with a motor and the water pump and it is submerged in the water. This type of water pump is used to pump water from deep wells and other sources like rivers. Owning this type of water pump has many advantages one being it will guarantee durability and saves money.
How does Electric submersible pumps Work?
The pump pushes water from the source to the surface by converting revolving energy into rotating energy and then into pressure energy. It happens when water is pulled into the pump. Water comes in where the impeller rotation thrust water through the diffuser and then to the surface.
Common Electric submersible pumpTypes
- Sump pumps
- Dewatering pump: To be fully submerged to avoid overheating and can be used to remove water in places like building sites or tunnels.
- Effluent/Sewage pump: Designed to be used in the waste water.
Advantages of Electric submersible pumps
- Efficiency: The performance is good due to the cool location of the pump.
- No chance of Overheating: Because they are placed underwater, they are not prone to overheating.
- Submersible water pumps can run continuously for a long time without any problem so long as you have a good source of water.
- Less noise: Because they are completely submerged, the sound is absorbed by the surrounding water.
- Greater Depth: Because they are designed to be placed underwater the pump can be used to pump water even at a depth of 10m.
Disadvantages
- Corroded seal: When the seal is corroded water may get into the motor damaging it until it is repaired.
- Because Submersible Water Pump are completely sealed,it makes them difficult when it comes to repairing
Price of Electric submersible pumps
The cost of submerged pumps may range between ksh:30,000 to ksh:150,000 and this depends on the type of submerged water pump and the amount of horsepower to deliver enough pressure. Also, the source of power determines the price like solar-powered pumps cost more expensive up to $2500.
Factor to consider before buying an Electric submersible pumps.
- Discharge height
- Cooling system
- Suction depth
- Size of the outlet/delivery pipe: The size of the pump where the water is to be pushed through.
- Type of water you are likely to pump.
- Backup system
- Water discharge rate
- Borehole/well size: This is the diameter of the well where the submerged pump is to be placed.
- Flow rate: This is the rate in terms of time for the submersible pump to pump a specific amount of water.
Conclusion
In my conclusion, submersible pumps are pumps that guarantee durability and have a wide range of ratings in capacity, speed in which the pump water, and the amount of energy used. These water pumps can also be used to pump other liquids not only water. They save time and money.
