Almost every infrastructure like schools, hospitals, residential buildings, and commercial outlets needs water. Water can be pumped up to any part of the building using water pumps. They are also used in various other sectors like mining, construction, agriculture, power generation, etc.
It is primarily used to move water in a compact system. Simply put, they are hydraulic machines used to increase the mechanical energy of the water and push it from the current level to the next level.
Like every other purchase, certain factors must be considered before purchasing a water pump. Read further to know them in detail.
It is essential to determine the water quality before purchasing water pumps. Pumps and motors are designed differently to suit different environments. Only the right one can work to its full potential. So, determine whether the pump will deal with clean or trash water.
The quality of the pump should be one of the non-compromising factors before making the final purchase decision. Never fall for a low price and compromise on brand. Take time to research and choose from the best brands available. Though branded pumps’ costs are higher, they can save much money in the long run as they have anti-rusting properties, excellent design, and high efficiency.
This factor directly demonstrated the effectiveness of a pump. It can be defined as the time taken by the pump to pump up certain quantity of water which is usually measured in litres per minute. The need for the flow rate is different in different industries.
So, you first know the requirement and then check for the flow rate to purchase. For instance, a pump used at home will need a flow rate of 100 to 200 litres per minute. While an industry or considerable farmland will need a flow rate of 2500 litres per minute.
Size of inlet
On average, the required size of the inlet will be up to 6 inches. It can also be more in specific industries. Most pumps work according to the centrifugal principle, where the water is sucked through the inlet and discharged through an outlet valve. The size of the inlet determines the amount of water sucked. So, the bigger the inlet faster the intake of water.
Head and pressure
It is the pulling capacity of the pump. The maximum head of water pumps points to the full depth of the water that can be pumped. Usually, the distance is measured in feet or meters. It is essential to decide on this factor in advance because, for instance, if you purchase a pump with a maximum head of 50 meters, you can only pump up to 50 meters.
The flow rate will turn zero if you try more than this limit. Typically, full head and pressure are preferred that is higher than the depth you want to pump the water as the depth of the water cannot be the same in most cases. So, if you need a pump to reach a depth of 50 meters, it is better to purchase one with 60 meters.
Types of pumps
There are many types of pumps working with varied principles to suit different needs. For instance, there are centrifugal pumps, vertical pumps, reciprocating pumps, rotary pumps, and pneumatic pumps. Know the kind of pumps you need and confirm their functions before purchasing them.
Thus, these are the essential factors to consider when you want to purchase pumps for your needs. Ensure that you never neglect the brand, type, quality, and other technical features to carry out the work properly.
