Introduction
• Centrifugal Pumps are the most popularly used 
due to their Smooth flow rate, Range of capacity, 
Design simplicity and Ease of maintenance and 
operations. 
• These pumps are expensive, and their repair or 
replacement is a cost burden for the business.
• Since they are an integral part of operations in 
most industries, their down time leads to huge 
revenue losses.
Usage of Centrifugal Pumps 
in various Industries:
• Water desalination plants: Centrifugal Pumps are most 
efficient at transporting solid containing sea water for the 
purpose of desalination. 
• Mining industry: In mineral processing precious minerals 
are separated from gangue and bitumen by centrifugal 
pumps. These pumps also help to process the minerals and 
are also used to transport the slurries and solid-containing 
fluids that accumulate during the mining process.
• Petrochemical plants: As centrifugal pumps are robust they 
help to transfer flammable and valuable petrochemical 
products. The production of plastics, rubbers, and dyes is 
also done through well-designed centrifugal pumps.
Common causes for 
the damage of 
Centrifugal Pumps:
• Seal damage resulting in Leakage.
• Bearing failure due to incorrect 
lubrication, misalignment, improper 
maintenance or high temperature of 
the pumped liquid.
•  Impeller failure due to improper 
heat treatment, poor surface finish 
or insufficient radial clearance 
between impeller and volute casing.
• Fracture of shaft and cracks due to 
Corrosive environment.
Solution
• To avoid these damages that result in downtime which will 
eventually lead to loss of revenue for these large-scale 
industries, it is best to continuously monitor operational 
parameters of the Centrifugal Pumps.
• However manual monitoring and inspection is:
Expensive
Not Accurate
Non-Comprehensive
 
Technology Solution
• For Centrifugal Pump stakeholders such as manufacturers, rentals, 
users or Support teams; pump monitoring can be done easily and 
remotely through IIoT based application. Such an IoT platform for 
these IIoT integrated smart pumping solutions comprise of three 
significant parts:
 Sensors, including cables and junction boxes
 Data collection device
 Monitoring/analysis software
• The sensors work to pick data from different hardware which is 
then relayed using GPRS/Internet/ Ethernet etc to a web-based 
application which stakeholders can access on their smart devices 
such as phones, laptops, and computers.
Benefits of the IIoT 
Solution
The IIoT Platform will allow close yet remote monitoring of following types of 
data:
• Vibrations/ Noise: Main reasons for excessive noise are impeller damage, 
misalignment, worn-out bearing, bent shaft or lack of prime. The IIoT 
platform helps to monitor noise levels and associated data.
• Temperature: A centrifugal pump gets overheated due to faulty packing or 
bearing, misalignment, and obstruction in delivery line. When the IIoT 
platform picks data on temperatures crossing the ideal threshold, 
corrective measures can be taken.
• Gap between the impeller and Pump Housing: This gap is an indication of 
Wear and tear of impeller blades leading to reduced pump efficiency and 
eventual plant downtime. As the impeller wears, the gap between the 
impeller and the pump housing increases.  Data regarding this gap can be 
collected easily through appropriate sensors used in the IIoT Platform.
