A pump is a tool for delivering mechanical energy to the liquid in the pump, which has a high fluid density. In terms of mechanics, there are three different types of pumps: centrifugal, rotary, and shaft/piston. The pump is the most commonly used device, whether in the home or the environment industry. The market is filled with a variety of water pumps. It is important to understand the specialty, correct quantity of water/pressure, and operation of each type of pump since this will assist you in selecting the appropriate type of pump for the available water supply. The purpose of this article is to compare and contrast the Centrifugal And Submersible Pump.
While both Centrifugal And Submersible Pumps use centrifugal force to transfer water and fluids through their systems, there are some variations between them.
Difference between Centrifugal And Submersible Pump
What is a Centrifugal Pump?
A centrifugal pump is a hydraulic device that uses the centrifugal force generated by the fluid to convert mechanical energy into hydraulic energy. A liquid is forced to move at a certain speed by this device, which rotates it into a flow. Every centrifugal pump is composed of mechanical parts that enable the pump to function.
Working Principle
Through the vane tips of the impeller, fluid is injected into the fast-spinning impeller along its axis and is ejected by centrifugal force along its circle. The fluid’s pressure and speed are both increased by the impeller’s motion, which also guides it in the direction of the pump output. The pump casing is specifically made to restrict the fluid entering the pump, guide it toward the impeller, then slow and regulate the fluid before discharging.
Installation Type
It comprises proper location, foundation, and coupling alignment. A Centrifugal pump is generally installed on the ground near the source of the water supply to reduce the suction lift issue.
Design & Configuration
It includes appropriate positioning, a solid base, and coupling alignment. To solve the suction lift problem, centrifugal pumps are often placed on the ground close to the water supply source.
Components of Centrifugal Pumps
- Shaft
- Impeller
- Casing
- Suction Pipe
- Delivery Pipe
Types Centrifugal Pump
Following is the classification of centrifugal pumps.
- Canned motor pump
- Magnetic drive pump
- Cryogenic pump
- Trash pump
- Slurry pump
- Chopper/grinder pump
- Circulator pump
- Multistage pump
Applications of Centrifugal Pump
- These pumps are used to pump ordinary water in buildings.
- They are engaged in services relating to fire protection.
- Lactose and other medications are transferred using centrifugal pumps in the pharmaceutical sector.
- In addition, they are utilized in refrigerants and coolant recirculation.
- Sprinklers, irrigation, and drainage systems all make use of these pumps.
Advantages of centrifugal pump
- Due to the lack of a driving seal, the pump is leak-free.
- Able to pump potentially harmful liquids
- Frictional losses are quite low.
- Requires less space
- No noise
- Compared to other pumps, centrifugal pumps experience the least wear.
- There is a space between the pump chamber and the motor, preventing heat transmission.
- The risk of destroying the motor is eliminated by the magnetic connection used in centrifugal pumps, which breaks apart under heavy loads.
- Chemical centrifugal pumps require less routine maintenance.
- Deal with the large volume
- Able to work medium to low heat
- Capable of transferring medium to low viscous fluid
Disadvantages of Centrifugal Pump
- In centrifugal pumps, magnetic resonance causes a little energy loss.
- Due to the magnetic drive’s attraction to particles, there may be a risk of pipe blockage.
- These pumps are susceptible to harm from the surrounding atmosphere’s vibrations.
- Cavitations are always a possibility.
- Because of insufficient flow, the pump may overheat.
- Although the multistage construction of this pump is costly, it is ineffective for high velocity.
- Operates incapable of high discharge pressures
What is a Submersible Pump?
A particular kind of centrifugal pump known as a submersible pump works by being fully immerse in the fluid it is intend to pump. Whether in a pond, tank, or other storage space, they are intend to remain that way during their operation. The mining industry, the navy, emergency services, sewage, and other industries are among their most frequent users.
Working principle
The suction pipe and pump must be filled with liquid before pump operation. When the pump is open, the impeller starts rotating at a high speed, ejecting liquid as it does so under the influence of centrifugal force. The liquid is then injected into the pump shell from the left outside impeller, where it slowly spreads at an indoor speed that gradually increases pressure until exiting via the pump’s outlet and into a discharge tube.
Installation Type
It is often mounted in open wells or borewells and stays submerge in the water.
Design & Configuration
The submersible pump is design to be submerged in water. These pumps’ motors often have oil-fill chambers that aren’t attached to the material covering them. The primary components of submersible pumps are an electric motor, a seal section, a pump cable, check and bleeder valves, and clamps.
The primary parts of a submersible pump are as follows.
- Clamps
- Check valve
- Submersible pump
- Pressure switch
- Torque arrestor
- Drain valves
- Relief valves
- Impeller
- Pump cable
- Sediment filter
- Inlet and outlet valve
Types of Submersible Pumps
The following are some of the submersible pumps available in the market.
- Deep well pump
- Submersible utility pump
- Water cooler pump
- Bottom suction pump
- Stainless steel pump
- Oil filled pump
- Mixed and axial flow pump
Application of Submersible Pump
- Pumping slurry, sewage, industrial fluids, and drainage are all done with single-stage pumps.
- They are also prevalent in aquarium filters.
- For usage in oil wells, water wells, and streams of water, multiple-stage submersible pumps are often discharge below the borehole.
- Only water that is clean, cold, and neither corrosive nor abrasive to the pump’s material should be pump using it.
- It is use in drinking water supply installations, pressure-boosting air conditioning systems, industrial plants, cooling water systems, fountains, seawater desalination, and other applications.
Advantages of Submersible Pump
- No issue of cavitation to a very great extent due to the extensive design.
- No noise due to submerged underwater
- Built to Handle Solids and Liquids
- Safer than different kinds of pumps
- The highest efficiency of all the centrifugal pumps.
- This pump does not require any priming.
- As the water pressure is increase naturally due to its design, there is no need for the extra need of electrical power to increase efficiency.
- Submersible pumps are hassle-free to install
Disadvantages of Submersible Pump
- Short lifespan due to being submerge in water.
- It is tough to maintain and clean due to its location.
- The pump can get starve and break its seal, enabling liquid to leak inside the motor housing and significantly harm the device.
- If the pump is not adequately submerge under the water, it may be damage.
- Compared to other centrifugal pumps, maintenance is more difficult and expensive.
- For wells, such as those for water, multiple-stage pumps are use.
In a Nutshell!
In order to extract water or other liquids, a Centrifugal And Submersible Pump is employ. However, because of structural differences, they have diverse uses since they are position in different areas.
We have made an effort to describe the differences between centrifugal and submersible pumps using a variety of criteria, including functioning theory, installation type, design and structure, application and use, benefits and drawbacks, etc.
Hope the information provided above helps you grasp the fundamental differences between different pump types.
