Water pumps may not be as flashy as the latest trending gadgets but they have been an indispensable tool for centuries, quietly providing the lifeblood of many industries and households. And while they may not be the most glamorous tool, they are certainly one of the most important. Let’s learn about how a water pump makes it possible for you to access clean and safe water within your homes. From “what are water pumps?” to “how does it work?” you will learn everything about water pumps from this article.

What is a Water Pump?
A water pump is used to move, compress, or transfer water from a lower level to a higher one. The main purpose of a water pump is to transfer water between two points and to get rid of excess water. It is often used in construction sites, tunnels, river beds, residential buildings, etc.
How does a Water Pump Work?
The basic mechanism of a water pressure pump primarily depends on the positive displacement principle in addition to kinetic energy to push the water. These pumps use AC or DC power to power the motor, whereas others can be powered by other types of drivers such as gasoline engines or perhaps even diesel engines. Let us understand the workings of a water pressure pump based on its type.
Manual pumps and their Working
You must have come across such pumps in small villages.
- A manual pump is operated by the person pushing a handle in an up-and-down motion
- You form a vacuum by pushing down on the handle, which shuts a valve on the spout and pulls water from the well
- When you lift the handle, the water pressure closes a valve to prevent the water from returning into the well while also opening the one in the spout to force the water out.
- This is probably the simplest and oldest method of moving water for you, and it can efficiently work in places with no electricity.
Jet Pumps and their Working
Jet water pumps are typically fitted above a well or any other water source. They function by sucking water from the well or source and pumping it into a tank that is specifically positioned for distribution. The jet well pump looks similar to a long straw. A vacuum is created in the system as the water is sucked in, which causes the water to be drawn up through it with the assistance of atmospheric pressure.
Centrifugal Pumps and their Working
Centrifugal pumps use an impeller to move fluid, which enters through the rotating impeller and exits via centrifugal force through the impeller’s tips. This boosts the velocity as well as the pressure of the fluid and directs it towards the pump’s outlet.
How to Choose a Water Pump?
Now that we have answered the big question, ‘How does a water pump work?’, it is now time to pick the right water pump for you. There are several different factors you must consider to pick the water pump that best fits your requirements.
For example, an electric water pump is a small water pump perfect for indoor use and requires relatively low maintenance, whereas a gas water pump is perfect for job sites and at farms for irrigation purposes. The following information will assist you in selecting the pump based on its operation, applications, and uses.
Types of water pumps based on working
There are mainly two types of water pumps based on their working:
1. Centrifugal Water Pump
Centrifugal pumps have a rotating impeller that can be utilised to supply water into the pump and force the discharge flow. Such pumps are available in a variety of types, such as trash, submersible, and standard models. All kinds of fluids with low viscosity can be pumped using these pumps. Furthermore, these pumps work well with thin fluids and provide high flow rates.
2. Positive Displacement Water Pump
Positive displacement pumps deliver a constant flow rate during mechanical contraction as well as the development of a stretchy diaphragm. Such pumps are used in a broad range of industries to control high-viscosity fluids and responsive solids. These are usually recommended for applications that demand a combination of high pressure and low flow.
Types of water pumps based on applications
1. Agricultural Pumps
Agricultural pumps are most commonly used in rural areas as necessary tools for good crop production. There are different types of agricultural pumps, including submersible pumps and centrifugal monoblock pumps. Submersible utility pumps are perfect picks for several water removal applications.
2. Residential Pumps
Given that they must be pumped into small areas, such pumps have quite a lower flow rate as well as less power compared to those used for agricultural purposes. Different types of residential pumps include self-priming regenerative pumps, submersible pumps, centrifugal pumps, borewell compressor pumps, and shallow well pumps. A booster pump is one of the most commonly used residential pumps. It is a water pump for a house that is used to increase the pressure in your water fixtures.
3. Speciality Pumps
These pumps are particularly intended for specific purposes. Some of the best examples of speciality pumps include sprinkler pumps, pond and fountain pumps, power take-off (PTO) pumps, pool cover pumps, electric chemical pumps, drill pumps, and condensate pumps.
4. Solar Pumps
A solar water pump is much more efficient than conventional pumps as it does not require a source of electricity to work. Solar pumps seem to be more costly to install initially; however, they may save you money on your energy bills over time.
Uses of a Water Pump
Water pumps are used for several different purposes based on their function and type. For example:
- Trash pumps are great devices to quickly move large amounts of dirty water.
- Submersible utility pumps are perfect picks for several water removal applications.
- Dewatering pumps can be used to move clean water from one location to another.
- A booster pump is a water pump for your house that is used to increase the pressure in your water fixtures.
- Sprinkler pumps are used to water lawns, gardens, and farmland.
- A speciality pump is perfect for fountains, ponds, sprinklers, pool covers, etc.
