The main types of centrifugal pumps
Centrifugal pumps are kinetic pumps which, thanks to the action of centrifugal forces, allow the liquid to first increase its kinetic energy and then transform it into pressure energy. Centrifugal pumps can be used in a wide range of industrial applications, offering high operational efficiency in terms of versatility and performance. The main types of centrifugal pumps include two configurations:
- Horizontal centrifugal pumps
- Vertical centrifugal pumps
The aim of this article is to clarify the main differences between the two types of centrifugal pumps while highlighting the most appropriate uses and related benefits.
What are horizontal centrifugal pumps?
Horizontal centrifugal pumps are one of the most widely used pump models within industrial applications. The design configuration involves aligning the pump head on the same plane with the pump motor. The positioning of the motor and pump head can be either close coupled (without couplings) or long coupled (with a coupling). The main areas of use include spraying systems (e.g., in the automotive or paint industry) and water purification systems for circulating very dirty liquids with suspended solids.
Application advantages of horizontal centrifugal pumps
Horizontal centrifugal pumps are easier to install and maintain because their design configuration makes them more accessible to the operator. Horizontal pumps can be easily adapted to different suction requirements and are particularly suitable for placement within plants where space is restricted.
What are vertical centrifugal pumps?
This type of pump has a vertical alignment in which the motor is positioned above the pump shaft. Also in this case the coupling between motor and pump head can be close or long where a spacer bracket acts as a support for the motor. The most frequent applications concern fluid transfer systems even with solid parts in suspension, lifting stations or fixed installations where the pump is immersed directly inside a tank.
Application advantages of vertical centrifugal pumps
Vertical centrifugal pumps are designed to lift fluid from an area of high depth. Compared to horizontal models, vertical pumps occupy a smaller footprint and are therefore an excellent solution for installations where the available floor space is limited. Vertical pumps are very well suited to pumping high-pressure fluids even at high temperatures. Vertical pumps use an electric motor, which in some cases may limit their uses.
Horizontal or vertical: which is the right pump?
Choosing the right pumping technology depends on a very high number of factors. At DEBEM we have a technical sales team that can provide support on the choice of the best pumping technology, be it horizontal or vertical. Do not make a choice if you do not have the right information. We will help you find exactly the right solution.
