In this video, Ruben Cobos, an engineer specializing in pumping equipment, will help you understand the difference between flow pumps and pressure pumps. Many times we find ourselves confused when choosing a pump, not knowing which one is more suitable to generate pressure or flow in different applications.
The video begins by explaining that when we need to raise water to great heights, such as 60 or 90 vertical meters, we require a high-pressure pump. This is crucial in situations where you need to build pressure to reach considerable heights, power wash, or even cut with water jets.
On the other hand, when a higher flow rate is required, such as in flooding applications in rice farming or shrimp farming, or in water evacuation situations, it is important to consider a pump that generates a voluminous flow
Ruben points out that no pump is exclusively of flow or pressure, since all pumps receive mechanical energy and produce hydraulic energy in both magnitudes: flow and pressure. Through clear examples, it shows how to identify if a pump has a predominant characteristic of high pressure or high flow, despite having the same power.
The video delves into the world of water pumps, explaining in detail the different types, features, and key components. It is divided into three main sections:
Positive displacement pumps: Pumps such as piston, gear, vane and peristaltic are mentioned. It is emphasized that piston pumps are the most used for pumping water in this group.
Centrifugal pumps: Special emphasis is placed on the impeller as the main generation element. Ruben explains how the diameter of the impeller affects the rate of acceleration of the liquid and the conversion of kinetic energy to pressure energy. Likewise, it is pointed out that the flow is related to the opening of the impeller and how this is reflected in the size of the pump.
Multistage pumps: It is highlighted that these pumps are useful to reach great vertical heights. He explains that multistage pumps have multiple impellers placed in series, allowing for a progressive increase in pressure stage after stage. It is mentioned that these pumps can be horizontal, vertical or submersible.
The video concludes with tips on the proper selection of pipes and fittings for high-pressure pumping installations. The possibility of using several pumps instead of a single high-pressure pump to avoid resistance problems in the pipes is also mentioned.
