Pump head is one of the most important parameters to know before purchasing a system. It is a highly technical specification, calculated in a complex way, but it indicates whether a certain pump is suitable for your needs. Otherwise, you may find yourself with a pump that fails to work in the required way, wasting time and money.<\/p>\n

In recent years, technological innovation has led to significant improvements in pump performance. Today, these are much more reliable and versatile than in the past. CDR Pompe<\/b><\/a> always strives for the highest quality and efficiency possible, and we can also assist you in selecting the best pump for your needs in the industrial<\/a>, chemical<\/a> and pharmaceutical<\/a> sectors.<\/p>\n

In this article we will tell you all about head, a type of parameter that you may not be familiar with. We\u2019ll explain what it is, how it is calculated and why it is essential to understand it.<\/p>\n

First let\u2019s clarify what is meant by pump head<\/h2>\n

\"\"<\/p>\n

The head is a very important physical quantity that indicates the maximum height to which a pump can lift a fluid.<\/b> In the most common measurements, it is expressed in meters. In essence, 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 delivery point (the outlet area or flange where the fluid exits the volute), taking into account any pressure drops caused by friction and other particular resistances that the system may have.<\/p>\n

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

The head is calculated as the sum of the geodetic head and losses in pressure, and is essential to ensure that a pump is suitable for the specific needs of a system.<\/p>\n

An insufficiently high head value can also cause malfunctions. As a result it is essential to know this value at the time of purchase. In summary, head is a key indicator of a pump\u2019s operational efficiency in the transfer of fluids in various application contexts, both industrial and beyond.<\/p>\n

How head is calculated<\/h3>\n

The formula to calculate the head is as follows: H= Hgeo + (Pa-Pe)\/* g + (va2-Ve2)\/2g + Hv<\/b>. We will now explain the individual elements of the equation.<\/p>\n
