Electric submersible pumps are multistage centrifugal pumps operating in a vertical position. Liquids, accelerated by the impeller, lose their kinetic energy in the diffuser, where a conversion of kinetic to pressure energy takes place. This is the main operational mechanism of radial and mixed flow pumps.Submersible Pump Basics
They are considered to be centrifugal pumps with no need for a suction pipe and almost always have the impeller and casing submerged. The pumps are most often used to move water and relatively thin liquids with or without solids depending upon the type of impeller.The submersible pump system consists of both downhole and surface components. The main surface components are transformers, motor controllers, junction box and wellhead. The main downhole components are the motor, seal, pump and cable.

What is the difference between submersible pump and centrifugal 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.
How does the submersible pump works?
A submersible pump pushes water to the surface by converting rotary energy into kinetic energy into pressure energy. This is done by the water being pulled into the pump: first in the intake, where the rotation of the impeller pushes the water through the diffuser. From there, it goes to the surface.
What does an impeller do?
An impeller increases the velocity of a fluid (a liquid or a gas) that is forced through a tube at an increased pressure. Pumps and compressors that use impellers are commonly used to transport fluids and gases in pipelines over long distances.
How long can a submersible pump run dry?
How Long Can a Submersible Pump Run without Water? You will not cause any damage to the pump if it runs without water for less than 45 to 60 seconds will not cause any damage. You can run the pump dry for a few seconds if you are using it for tank transfer and you would like to empty the tank.

Does a submersible pump have a check valve?
Check valves are an important component of every submersible pump water system. Why are check valves important? First, they allow your water system to maintain pressure when the pump shuts off. They also prevent backspin, up thrust and help minimize water hammer (more on this later!).

Why does my submersible pump keep tripping out?
One common cause of a submersible pump tripping its breaker can be cracks or leaks in the housing. If your pump’s housing is cracked, water could be getting into the pump through these cracks and causing it to short circuit. The same can be happening if you have a leak in your pump which is letting water in.
How do you troubleshoot a submersible pump?
- Check for blown fuses and tripped breakers.
- Check the Voltage. Voltage needs to be at +/- 10% of motor ratings. …
- Check Pressure Switch. …
- Check the Control Panel. …
- Check Splice Connections. …
- Check the Pump and Motor.
Can a submersible pump be centrifugal?
A submersible pump is a centrifugal pump (Figure 1), which is attached to an electric motor and oper- ates while submerged in water. The sealed electric motor spins a series of impellers (Figure 2). Each impeller in the series forces water through a diffuser into the eye of the one above it.
Is a submersible pump better than a jet pump?
Jet pumps pull water, while submersible pumps work by pushing water upward. Since pushing water requires less energy, submersible pumps are often more efficient for deep wells. Choosing a jet pump or submersible pump will likely depend on the depth of your well.
What is the opposite of a 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 you fix a submersible pump?
The submersible pump must be removed from the well before it can be repaired. Remove the pump and associated piping from the well to repair a deep-well submersible pump. The pump is made up of a motor and an impeller. It may also have a check valve to prevent back-flow and a tail pipe attached below the pump.
How do you clean a submersible well pump?
- Materials. flashlight. …
- Remove The Pump From The Well. Turn off the power to the water pump. …
- Eliminate Debris From The Interior And Exterior. Fill a bucket with water and add a small amount of detergent and bleach to it. …
- Replace The Filter And Secure The Pump.

Is an impeller the same as a water pump?
The heart of the cooling system of your vehicle is the water pump, and as a key part among its components to carry out its function, there is the impeller.
What is pump impeller?
An impeller is a rotating iron or steel disc with vanes in a centrifugal pump. Impellers transfer energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid radially outwards from the centre of rotation.
