But what types of centrifugal pumps are out there, and what are their applications?
Choosing the appropriate type of centrifugal pump is essential for successful pumping
operation. There are a variety of centrifugal pumps in the market with unique features,
functions, and capabilities.
It’s important to know about the various centrifugal pump types to ensure you select the
right pump for your application.

2. In this blog, we will introduce you to the different types of centrifugal pumps, their
features, technical specifications, and applications so you will know which pump suits
you the best.
What Is A Centrifugal Pump?
A centrifugal pump is commonly used for transporting fluid in various industries by
converting rotational energy into kinetic energy generated from impellers.
These pumps are renowned for providing the best performance in a wide range of
applications. It has unique features like energy efficiency, high operating reliability, safe
fluid handling, low maintenance, heavy-duty design, high productivity, and versatility.
Working Principle Of Centrifugal
Pumps
As mentioned above, centrifugal pumps move fluids through energy generated from
impellers; let’s quickly understand the working process in detail.
First, the liquid enters the centrifugal pump suction, which further moves the rotating
impeller. This rotating impeller rotates through energy received from the pump motor,
engine, or turbine.
Centrifugal pump impellers convert rotational energy into kinetic energy and push liquid
outward by centrifugal force.
Lastly, fluid enters inside the volute where its velocity reduces, and pressure increases to
get outside from the discharge nozzle.
Different Types Of Centrifugal
Pumps
1. Semi-Open Centrifugal Pump

3. Semi-open centrifugal pumps are generally pumps with semi-open impellers. It has
impellers that are not covered by a shroud and are semi-open, which allows solids to
pass through the impeller easily without clogging. This type of centrifugal pump is ideal
for handling liquids with high solids.

2. Side Suction Centrifugal Pump










Suction centrifugal pumps have two different types - single and double suction
centrifugal pumps. Suction pumps with single suction are ideal for smaller flows, while
suction pumps with double suction are suitable for large flows.

Features Of Side Suction Centrifugal Pump:
 W/o. Mechanical Seal Gland Less Design

 Ammonia
 Condensates
 Filter Press 24”, 36”, 48”, 60”, & Other Industrial Application

6. 3. Closed Impeller Centrifugal Pump









A closed impeller centrifugal pumprefers to a pump with closed impellers. Its impeller
is fully covered by a shroud as it is designed with added wall sections on both the front
and back sides of the vanes.
Centrifugal pump with a closed impeller is suitable for fluids with low solids and high
flow rates. It can not be used for pumping solids due to the risk of clogging and other
wear, which can cause inefficient performance.
Features Of Closed Impeller Centrifugal
Pump:
 Maintenance Free
