We are so used to having water in our homes and in our day to day that many times we do not give the necessary importance to the fact of how it reaches us. It is interesting to stop and think how things happen, and in this case we will focus on the work of water pumps in our daily consumption.
What’s a water pump for?
Today we see this team at the heart of the operation of many applications for various fields such as agriculture, industry or at the level of private residences. Let’s look at some more concrete examples of these uses of water pumps:
- Allows you to draw water from the bottom of a well.
- In an uneven terrain, he manages to move the water from one place to the other.
- Improves irrigation of agricultural or growing areas through a traditional system or some irrigation system, such as spraying.
- It helps us to fill as much as to empty a pool, pond or any enclosure with water.
- Increases water flow.
- Drain shallow areas that are flooded.
- Improves the distribution of products such as fertilizer and pesticide evenly throughout water.
- In the construction area it is also used for various processes or applications.
Key parts of a water pump
Although there are many types of water pumps, there are a number of components that are present in all of them, and the most important are:
- Housing: protects the mechanism from the outside and above all should protect against corrosion.
- Inlet and Outlet Ducts: Also known as suction and drive.
- Impellers: water impellers. Blades, etc.
- Seals, retainers and rings: these tools ensure that the pump is tightly closed and generate a certain compression.
- Impeller axis: element on which the impeller rotates.
- Bearings: hold to the shaft.
- Control panel: through this panel we start the pump or we can stop it.
- Engine: Last but not least, the engine will put the above elements into action to finally move the water. Depending on the power the movement will be one or the other. It can contain additional elements depending on the model.
What are the main types of water pumps?
When we talk about types of water pumps we can not offer a unique classification as there are many different classifications depending on the context in which you are. In this case we are going to give you a fairly technical cataloging based on the type of operation of the hydraulic pumps, and we will distinguish 2 types:
Centrifugal water pumps
Through a rotating impeller moves the water and thus pressurize the discharge flow. These pumps do not process only water but are capable of processing many other liquids, such as milk, wine, etc., as long as they are light. In addition, they also support liquids with high flow rates. The most common applications of centrifugal hydraulic pumps are:
- Pump water supply into buildings
- Following the relevant standards, offer pressure on fire protection systems.
- Help the circulation of hot water in a closed system.
- In cesspools
- Increase pressure in any water intake in general.
- Water supply of a well for domestic use.
Positive displacement water pumps
This type of pumps consists of a flexible diaphragm which performs contractions and mechanical expansions to supply a fixed amount of flow.
In turn, these pumps are subdivided into two types: reciprocating or rotating. Both are specialists in handling liquids with a high viscosity content or containing quite sensitive solids.
The most common applications of these hydraulic pumps are:
- They are highly recommended in systems that have a low flow rate, but with a fairly high liquid pressure
