Water pumps are an important part in most of the Indian households. They are available in different types and capacities, so you have to choose based on your necessities.
In this article, we shall discuss the various types of pumps, their functionalities, and their pros and cons.
By the end of this write-up, you will be able to discern which type of pump you will need depending on your application.
What Are The Different Kinds Of Pumps Available In The Market?
Pumps are basically of two types, and they are – domestic and agricultural pumps. These pumps are further available in different designs and kinds. Each of these works in a different way. Based on your needs, you can choose the right one for your application.
To help you gain better insights, we further discuss about each type and its classifications. It will give you a clear understanding of which pump to choose.
As the name goes by, domestic pumps are those exclusively designed for use at homes. You can use these pumps for daily water consumption in the houses. In comparison to the agricultural pumps, the water flow rate and power of these pumps are less. It is because the purpose of the domestic pumps is to pump water into small areas, unlike their counterparts. You can further classify domestic pumps into the below types:
- Self-Prime Regenerative Pumps
- Centrifugal Pumps
- Submersible Pumps
- Bore Well Compressor Pumps
- Pressure Booster Pumps
- Shallow Well Pumps
Let us discuss the salient features about each type in detail below:
1. Self-Prime Regenerative Pumps
These pumps have the self-priming capacity and hence the name self-prime regenerative pumps.
The self-prime regenerative pumps feature vanes, rim, and impeller. The vanes come fitted on either side of the rim. This rim is a ring-like conduit present in the casing of the pump. The discharge of the fluid does not happen through the impeller’s tip. Instead, it gets re-circulated to the bottom, from where the fluid is released. The regenerative pump re-primes itself through this re-circulation or regeneration.
The regenerative pumps can remove air because of their self-priming capacity. They do not require any foot valve to suck the water from the pipelines.
The self-prime regenerative pumps can handle cold freshwater that is free from abrasive particles and other substances that are chemically aggressive. Hence, these pipes are ideal for domestic water supply. You can use them for your lawn sprinklers, and water supply for gardens, etc.
- The self-prime regenerative pumps are compact size.
- These pipes are easy to carry.
- The regenerative pipes are very economical in nature.
- These are incredible solid handling pumps.
- They do not require any foot valve.
- The self-prime regenerative pumps are less efficient.
- These pumps require a larger clearance for dealing with solids.
2. Centrifugal Pumps
Centrifugal pumps are those that have a very high discharge in comparison to regenerative pumps.
These pumps feature an electric motor that helps circulate water by converting rotational kinetic energy to the hydrodynamic energy of water flow.
Jet centrifugal pump is another type that uses a similar mechanism. However, it enhances the water drawing capacity from underground resources with help of a stream of sucked water.
You need to install the centrifugal pumps with a high-quality ISI foot valve.
Centrifugal pumps have a very high discharge than regenerative pumps. Moreover, they have excellent hydraulic performance and also higher operating efficiency than the latter.
The centrifugal pumps can handle cold freshwater that is free from abrasive particles and other substances that are chemically aggressive. Hence, these pipes are ideal for domestic water supply. You can use them for your lawn sprinklers and water supply for gardens, irrigation, small farms, swimming pools, etc.
- Centrifugal pumps have a very high discharge than regenerative pumps.
- They have excellent hydraulic performance and also higher operating efficiency.
- They require less maintenance.
- These pumps offer a constant and steady water supply.
- In the case of high viscosity feeds, these pumps become inefficient.
- To lift the water, you either need to place them underwater or prime these pumps.
3. Submersible Pumps
As the name goes by, you need to submerge these pumps completely in the water.
The submersible pumps feature a sealed motor that you submerge completely in open wells and also bore wells.
Unlike other pumps, the submersible pumps do not require any priming. They are very efficient, too.
The submersible pumps are available in two types. They are:
- Open Well Submersible Pumps
- Tube Well submersible Pumps
Let us discuss about these types below:
Open Well Submersible Pumps: These pumps are exclusively for open well applications.
Tube Well Submersible Pumps: As the name suggests, these pumps are specially for bore well applications.
The submersible pumps can handle cold freshwater that is free from abrasive particles and other substances that are chemically aggressive. Hence, these pipes are ideal for bore wells having a diameter of three inches. 3.5 inches and four inches.
- The submersible pumps do not require any priming.
- These pumps are very energy-efficient.
- Since you submerge these pumps completely in water, there are no cavitation issues.
- These devices are quiet when operating inside the water.
- Since you submerge these pumps completely in water, it is difficult to notice any fault in them.
- Any malfunction in the seal can damage the motors.
- It is very difficult to repair these pumps.
4. Borewell Compressor Pumps
As the name suggests, the bore well compressor pumps are exclusively for drawing water from deep bore wells with specific diameters.
These compressor pumps feature air pressure in the system that helps in lifting the water from deep bore wells.
The borewell compressor pumps are available in two types – monobloc and belt-driven pumps. You can use these pumps in bore wells that contain muddy water and where tube well pumps are not suitable.
The borewell compressor pumps are ideal for bore wells of less yield and have a depth of up to 600 ft.
- The borewell compressor pump comes designed with a tightly contained unit. It helps in keeping the water out of the casing and internal components.
- These pumps require less effort when working on salty and muddy water.
- You place the compressor pump inside the liquid. Hence, they are more efficient and consume less power.
- The area wherever you install the compressor pump machine depletes fast.
- Using a compressor pump may result in drought-like conditions and can lower the quality of soil or vegetation.
5. Pressure Booster Pumps
As the name says, the pressure booster pumps are specially designed to boost or increase water pressure.
The pressure booster pumps feature an automated pumping system. When the water pressure at your home drops to a defined level, the pump will automatically start pumping water. It stops the moment when the outlet pressure reaches the pre-set stop pressure.
The pressure booster pumps are engineered in a way that supplies you with the required water pressure based on your needs.
These pumps are for installing in places with low water pressure. They are ideal for use in residential buildings.
- The pressure booster pumps boost or increases the water pressure.
- These pumps ensure a constant supply of water.
- These pumps come in compact sizes, and hence you can install them inside your houses.
- You can use the pressure booster pumps for both residential and commercial purposes.
- During high pressure, these pumps tend to make a noise and are louder.
- In case of improper pressure, the pump may remain on for a shorter duration.
6. Shallow Well Pumps
As the name says, shallow well pumps are exclusively for shallow wells.
The shallow pumps feature a suction head of up to eight meters that has great suction power.
These pipes are the best alternative for other pipes like self-prime pumps that usually come with a suction head of more than six meters. They easily fit wells having a small diameter.
The shallow well pumps are the best bet for shallow wells. They are ideal for rural areas.
- The shallow well pumps fit perfectly with wells, having a small diameter.
- These pumps are very easy to install.
- The shallow well pumps are lightweight and are very handy during disasters or emergencies.
- The work with wells of any yield.
- These pumps have high resistance to corrosion, rust, and wear and tear. Hence, they are very durable.
- They require less maintenance.
- The shallow well pumps are very affordable than the other pumps.
- The shallow pumps become less effective when the level of lift increases.
- The mechanical seal of the shallow well jet pump can leak and wear out easily when it pumps water containing sand.
- You should never run the pump if the casing does not have water. Any air or gases in the pump can make the pump lose its prime.
Agricultural pumps are exclusively engineered for agricultural applications. They are a saviour in the rural areas and facilitate good crop production. You can further classify agricultural pumps into the below types:
- Centrifugal Monoblock Pumps
- Submersible Pumps
1. Centrifugal Monoblock Pumps
The centrifugal monoblock pumps are just like the regular centrifugal pumps.
They have the same design and working mechanism as the centrifugal pumps. These pumps feature an electric motor that helps circulate water by converting rotational kinetic energy to the hydrodynamic energy of water flow.
The only difference is that they cover a larger area than the domestic centrifugal pumps. They have high efficiency than the latter and also a higher rate flow, which is about 25 LPS.
2. Submersible Pumps
The submersible pumps are similar to the domestic submersible pumps.
They have the same design and working mechanism as the submersible pumps. They feature a sealed motor that you submerge completely in open wells and also bore wells. The agricultural submersible pumps do not require any priming. Moreover, they are very efficient, too. And the best part is that they are available in a wider range.
The agricultural submersible pipes are available for regular open wells and also for bore wells having a diameter of three inches. 3.5 inches and four inches. They have a high power of 60HP and offer a maximum operable depth of 1640 feet. They provide a higher rate flow, which is around 38 LPS.
