A Centrifugal pump is a popular choice for industrial applications such as sugar processing, paper production, and many more. These pumps are extremely efficient and can handle a wide variety of liquid flows and pressures, making them ideal for heavy-weight applications. There are two types of inline centrifugal pumps:
- Horizontal
- Vertical
Today’s post will explain the differences in these pump types and give details about each to help you make the best decision. Fundamental differences between Horizontal and Vertical Centrifugal Pumps The shaft’s shape and placement is the main difference between the two pumps. The horizontal centrifugal pump inline has a shaft placed horizontally, as the name suggests. It can be placed between the bearings, or it can be overhung. The vertical inline pump, on the other hand, has a shaft that is vertically positioned. The shaft design is similar to the previous type. It is radial split and has an overhang. How do you choose between Horizontal and Vertical Inline Pumps? You have to choose between vertical or horizontal when choosing. Horizontal pumps Convenience is a key factor to remember. What works well for one application might not work for the other. We have listed the pros and cons for each so you can make the best decision.

What is good in Horizontal Centrifugal pumps?
- Easy installation and maintenance, as internal parts such as the rotor, can be accessed easily.
- For applications that require low suction pressure, opt for an overhang shaft design.
- For applications that require high suction pressure, opt for an in-bearing shaft.
- Secure coupling to external accessories such as engines, electric motors, or turbines
- There are many nozzle configurations that can be used to meet external piping needs such as:
- Top suction top discharge
- End suction top discharge
- Side suction side discharge
- The pump is ideal for indoor use because it has low headroom. This allows it to fit comfortably even in small spaces.
Why not Horizontal Centrifugal pumps?
- Vertical centrifugal pumps have lower working temperatures and pressures.
- Not suitable for applications that have a NPSH greater than the NPSH is currently available. Here, NPSH is the net positive suction header.
- Horizontal designs have a larger footprint than vertical pumps.
The advantages of vertical centrifugal pumps
- Horizontal pumps have a smaller footprint.
- This product is suitable for applications with a restricted surface area.
- You can modify the NPSH to suit a variety of purposes.
- This is suitable for liquids that have high pressures or high temperatures.
Why not Horizontal Centrifugal pumps
- Large headroom is required, which makes installation and maintenance difficult, especially when multistage turbine pumps are used.
- The coupling capabilities are limited. Only works with electric motors, not with turbines or engines.
- It is expensive to dig a pit and build a barrel, especially for multi-stage units.
- Pumping liquids with high concentrations of dissolved gas can be difficult and mechanical seals may fail.
The bottom line We hope you now have a better understanding of the pros and cons of each type. We can help you choose the right type of pump for your particular needs.
