Horizontal and Vertical Multistage Centrifugal Pumps

Horizontal Multistage Centrifugal Pumps

This type of pump has a segmented casing with modular inter-stage components. The rotating assembly is held between bearing housings, making the assembly more balanced for high pressures.


They typically handle higher flow rates than vertical multistage pumps (with the exception of vertical turbine pumps).


The horizontal configuration of multistage pumps is best applied in applications like these:


Reverse Osmosis

Boiler Feed



Pressure Boosting

High Pressure Cleaning

Snow making


This type of pump is pretty maintenance intensive, however. It takes a high skill set to work on these pumps and ensure they are put back together properly. They can also be quite costly upfront, depending on the degree of specification required and the materials of construction.


Vertical Multistage Centrifugal Pumps

Vertical multistage centrifugal pumps have a vertical shaft, where stages are stacked one on top of the next. (Disclaimer: Although vertical turbines are technically multistage pumps, these are not the types of pumps we’re discussing here. )


Clearances are small in these pumps, therefore, clean water applications are best for this pump:


High pressure shower systems

Boiler feed water

super heater feed

Vertical multistage pumps are great for areas that don’t have much footprint to spare. Its ability to deliver high pressure output with a single pump body and motor combo is also a plus.


It is important to keep in mind, however, that this type of pump does not tolerate debris or significant solids, and is also vulnerable to deadhead conditions.


Multistage pumps provide many key benefits, from energy savings, to ability to operate in a wide range of flow/head scenarios. If you think it might be right for your application, be sure to discuss with a qualified engineer first. They’ll make sure the right pump is selected specifically for your purpose.
