The head of a pump is one of the most important parameters to know before purchasing a system. It is an extremely technical value, which is calculated in a complex way but indicates whether that type of pump is suitable for your needs. Alternatively, you might end up with a pump that cannot work as required, wasting money and time.<\/span><\/p>\n

In recent years, technological innovation has led to significant improvements in pump performance. Today, they are much more reliable and versatile than in the past. We at <\/span>CDR Pompe<\/b><\/a> we always work striving for the highest quality and the greatest possible efficiency, and we can also guide you in making the best choice for your pump in the field of <\/span>industrial<\/span><\/a>, but also <\/span>chemical<\/span><\/a> e <\/span>pharmaceutical<\/span><\/a>.\u00a0<\/span><\/p>\n

In this article, we want to talk to you about prevalence, a type of parameter that you may not be familiar with. We will try to explain what it is, how it is calculated, and why it is essential to know it.<\/span><\/p>\n

We understand what is meant by pump prevalence<\/span><\/h2>\n

\"\"<\/p>\n

Prevalence is a very important physical quantity that indicates <\/span>the maximum height a pump can lift a fluid.<\/b> In the most common measurements, it is expressed in meters. Essentially, head refers to the pump's ability to overcome the difference in height between the suction point (the area from which the liquid enters the pump) and the discharge point (the outlet area or flange where the fluid exits the casing), taking into account head losses caused by friction and other specific resistances the system may have.\u00a0<\/span><\/p>\n

We could also define the prevalence of a pump using other words, such as <\/span>the energy per unit mass supplied by the pump to a fluid.<\/b><\/p>\n

The head is calculated as the sum of the static head and the head loss, and it is essential to ensure that a pump is adequate for the specific requirements of a system.\u00a0<\/span><\/p>\n

A prevalence value that is not high enough can also cause malfunctions. Consequently, it is essential to know this value at the time of purchase. In summary, prevalence is a key indicator of a pump's operational efficiency in fluid transfer across various industrial and other application contexts.<\/span><\/p>\n

How to calculate prevalence<\/span><\/h3>\n

\"\"<\/p>\n

The formula for calculating prevalence is as follows: <\/span>H = Hgeo + (Pa-Pe)\/g + (va^2 - ve^2)\/2g + Hv<\/b>. We will now explain the individual elements of the equation.<\/span><\/p>\n
