Despite the similar names – practically synonymous, there are significant differences in their structures and use.
(Glauco Cisz – Engineering and Sales)
It is not new that the issue of water supply is a very common problem in several Brazilian regions. The lack of water to carry out essential activities such as power generation and basic sanitation significantly worsens the economy and also the routine of Brazilian families.
This problem is mainly due to the long periods of drought and drought, which lead to low (and worrying!) levels in the reservoirs, as you may have heard at some point in recent times.
And what about industrial activities that need water to guarantee their production? It is true that studies are being carried out and various solutions have already been applied to reduce the use of this natural resource, but water is still an essential asset for most manufacturing systems.
For some rural producers, this dependence on water supply is even worse, as in many cases the productive areas are far from the distribution network. In these cases, they need to create artificial wells and dams to implement their irrigation systems.
This is where motor pump designers and manufacturers come in, who continue to develop increasingly specific and dedicated models for the various applications and demands that require the movement of liquids, in a continuous search for more efficient models to meet certain needs.
In this line, a subject that usually causes doubts and discussions when dealing with motor pumps that are immersed in the pumped liquid is about the submersible and submersible models.
What do you think? Do the two deal with the same equipment or in fact different items? You can rest assured that we will explain this to you now!
In a more general view, these two terms are used interchangeably. According to the Priberam dictionary (http://dicionario.priberam.org):
- Submersible: that can submerge; go to the bottom; hide in the water.
- Submerged: which is completely covered in water or another liquid; immersed, dipped, submerged.
However, these two very similar nomenclatures end up being used in the pumping area for different applications and that is why this doubt about the difference between submersible pump and submersible pump ends up being quite common.
So how do you know which “type” to use in each situation? To solve this and other doubts you may have on the subject, we will detail here the main characteristics of each one of them.
We call a submersible pump a very specific model of motor pumps, designed to pump clean water from great depths such as artesian wells and other underground structures. As the name implies, it is a device that works immersed in water. It is a compact equipment frequently used to supply cisterns and water tanks and also for irrigation.
Also called pen or stick pump, due to their thin and long shape, you can find them in different power, flow or pressure configurations. The main objection to the use of this equipment is the pumped liquid, which must necessarily be clean water, since the presence of impurities and solid particles can damage the equipment.
Submersible pumps are equipment designed to pump liquids with the most diverse types of impurities and contaminants, such as dirty water or untreated sewage, with solid particles of the most varied sizes and compositions. They are robust equipment, widely used in water and sewage treatment plants, condominiums, hospitals, industrial kitchens, slaughterhouses and slaughterhouses, as well as in industry and agriculture in general.
Submersible pumps can also be equipped with grinding elements installed in the casing suction (volute), allowing their use in even more adverse environments and without compromising their useful life.
And now, is the difference clearer? Simple but very relevant! Despite being very similar equipment in terms of installation and similar names, submersible and submersible pumps are designed and implemented to meet different needs and projects.
But attention: much more than knowing the difference between the models of pumps and motor pumps, it is necessary to pay attention to the specifications, the range of pressure and flow range and, most important of all, the reliability of the product and its manufacturer. In that case, you already know: FAMAC is the right choice!
See you shortly!
