Horizontal Vs Vertical: Which Centrifugal Pump To Choose?

Dec. 23, 2021

As part of your research into centrifugal pumps, you need to determine whether a horizontal or a vertical design is best suited to your specific needs. Although the two operate in much the same way, there are still significant differences. The information provided will help. Of course, you can gain more valuable information when working with a reputable manufacturing company.


Of all the equipment used, centrifugal vacuum pumps are the most common. Not only are they very efficient, but they are also built to last. For these pumps, you have two main options - vertical or horizontal.

When looking at the two options for multistage centrifugal pumps, the main differences relate to the position and shape of the shaft.


Horizontal - For horizontal centrifugal pumps, the shaft usually runs horizontally. However, sometimes it is placed between or suspended from the bearing design.

Vertical - In contrast, the shaft of a vertical centrifugal vacuum pump runs vertically. This means that the unit is designed with a radially split or overhanging housing.


Vertical centrifugal pumps are machines of simple design and have similarities to horizontal pumps. The casing, known as a worm housing, contains an impeller mounted vertically on an upright (vertical) rotating shaft. The electric motor uses its mechanical energy to turn the pump impeller with its vanes and transmits kinetic energy to the liquid as it begins to rotate. These pumps can be single or multi-stage, with multiple stages mounted in tandem.


So, is one type of pump better than another? Not necessarily. Instead, it mainly comes down to convenience. In addition, you need to consider the advantages and disadvantages of each method to help you make the right choice.


Horizontal centrifugal pumps

These multi-stage centrifugal pumps are much easier to install and maintain. The reason for this is that this pump type allows easy access to internal parts. You can connect these pumps to engines, motors or even turbines. You will also have a variety of nozzle configurations, including side suction with side discharge and end and top suction with top discharge. This is a great option if you are interested in equipment for indoor applications, as these pumps require very little headroom.


Vertical centrifugal vacuum pumps

Vertical pumps have many other advantages. For example, they require a much smaller footprint compared to horizontal centrifugal pumps. If you have limited floor space, these pumps are a good choice. You will also find that using these pumps can improve NPSH. another consideration is that the unit is suitable for high pressures and high temperature fluids.


Which is the right one?

When choosing from these two different types of multistage centrifugal pumps, it is entirely up to you. As you can see, both have their advantages. Therefore, you need to choose the right pump for your needs.
