All You Need To Know When Choosing Between Horizonal or Vertical Multistage Centrifugal Pumps
Multistage centrifugal pumps have multiple impellers and volutes
(stages) that connect in a series, allowing the liquid to flow
from one stage to the next at increased pressure. The liquid
enters the first volute or chamber at suction line pressure
and exits at elevated pressure. The fluid then enters the second
stage where the pressure increases and continues through each
chamber until discharge. Each stage that the liquid passes through
increases the pressure until discharge, at the highest pressure.
Applications for multistage pumps
What makes multistage pumps unique is that they can produce higher pressure at each stage yet retain a constant flow. They're also one of the more energy-efficient pumps for many different applications.
Multistage pumps are popular in pressure-boosting applications
(for example, to push water up to high rise buildings), reverse
osmosis (RO), boiler feed water, spraying and high-pressure
cleaning, waterworks and water circulation, irrigation, heating
and cooling/conditioning, wash down facilities, oil & gas
production and power generation & mining.
Horizontal Multistage Centrifugal Pumps
This type of pump has modular components with a rotating assembly located between bearing housings. The shaft of horizontal centrifugal pumps is horizontal, which makes these pumps particularly suited to indoor applications where they require less headroom.
A horizontal centrifugal multistage pump is balanced at high pressures, which means it can handle higher flow rates than vertical multistage pumps. However, horizontal stage pumps require somewhat more complicated mounting due to expansion/contraction issues. They can also be expensive upfront and difficult to maintain.
Vertical Multistage Centrifugal Pumps
A vertical multistage pump has a shaft that runs vertically,
with stages stacked on top of each other. Above ground, they
are well suited to applications with space limitations or less
ground surface, or where you need to increase NPSH. They work
well for both high-pressure output and higher temperature fluids
but have minimal clearances which makes them suited for clean
