One of the most commonly used types is the submersible pump. Its ability to pump water in extreme conditions such as floods and puddles makes this type of pump widely functional.
How Submersible Pumps Work and Their Functions
Submersible pumps, also known as submersible or immersion pumps, are designed to function underwater and pump water to higher points or positions. So, in simple terms, the way submersible pumps work is by pushing water from around the pump casing to the output points.
With this operation, the general functions of submersible pumps include:
Pumping water from deep wells to the surface. Pumps used for deep wells, or deep well pumps, come with various head capacities ranging from 20 meters to 200 meters.
Draining water from shipyards or ponds. Due to their ability to work underwater without damage, submersible pumps are popularly used in such working environments.
Supplying water in agricultural industries as part of irrigation systems. Submersible pumps can work well for pumping water containing certain materials such as mud.
Tips for Choosing Submersible Pumps
When applied, submersible pumps do not require as much energy as other pump types when performing a series of pumping processes in the same location. This is because submersible pumps utilize water pressure in pumping.
In terms of lifespan, this type of pump is generally stable and capable of working optimally for long working hours. Because submerged in water, the pump machine will not overheat, which in most other pump types can lead to explosion.
Things to consider in using submersible pumps:
Some submersible pump companies do not use high-quality casings, making them prone to corrosion given the pump's continuous submersion in water.
Not all submersible pumps are suitable for use in poor quality water, muddy water, or floods. In this case, pump components quickly deteriorate when exposed to dirty water. Therefore, users should be selective when purchasing.
Use the following tips when buying a submersible pump:
Pump capacity
Like other types, submersible pumps available in the market today come in various capacities. Some can pump 7,500 liters per hour, 18,000 liters per hour, and so on. Therefore, match your needs with the pump capacity available.
Check the pump's delivery head
Delivery head refers to the maximum height at which the pump can lift water. Some pumps have an eight-meter delivery head, while others can only lift up to five meters. Therefore, adjust the pump according to the terrain where it will be applied.
Consider between automatic and manual pumps
Submersible pumps with automatic operation have more advantages than manual pumps. However, if a manual pump is more relevant to your current needs, there is no harm in using that type. Both have the same capacity.
Check additional accessories
It is possible that pump companies include additional features in submersible pumps with specific functions. As a buyer, you are free to decide whether these features are necessary or not. It should be noted that the inclusion of several features often increases the amount of power required by the pump. So, if the features are not too important, opt for a standard pump type.
