Centrifugal pumps are commonly used in industries like chemicals, pharmaceuticals, and food processing to handle liquids easily. These pumps use the spinning motion of an impeller (a part with curved blades) to move and pressurize fluids, making them perfect for transferring, mixing, or circulating liquids in different processes.
How Centrifugal Pumps Operate
These pumps work in a simple way: when the impeller spins, it pushes the liquid outward with force, creating pressure that helps the liquid flow smoothly through the system. Their easy-to-use design and reliability make them popular for chemical processing, but they still come with a few challenges.

Tackling Common Chemical Processing Issues with Centrifugal Pumps
Pressure Drops and Bubbles
When the pressure inside the pump drops, vapor bubbles can form, which can damage the pump and lower its efficiency (this is called cavitation).
How pumps help: These chemical centrifugal pumps with low NPSH and specially designed impellers, like Fristam’s, manage pressure better and work more efficiently.
Leaks
Leaking seals or gaskets can lead to fluid loss, contamination, and safety issues. For industries like chemicals or food processing, maintaining sterility and avoiding waste are critical.
A smart solution: Fristam’s FPV centrifugal pump used in industry have special seal designs to reduce leaks and keep the system clean and reliable.
Flow Variations
Changes in demand can cause inefficiency, waste energy, or even damage the pump.
The fix: Pumps with control systems or VFDs (Variable Frequency Drives), like Fristam’s, can adjust the flow as needed and handle rates up to 550 m³/h.
Clogging from Particles
Solid particles in the liquid can clog the pump and disrupt operations.
The solution: High discharge pressures, like the 28 bar from Fristam pumps, ensure smooth and hygienic liquid flow, even with challenging fluids.
Overheating Issues
Thick liquids or low flow rates can cause the pump to overheat, leading to damage.
What helps: Choosing the right size and type of pump, like Fristam’s range, prevents overheating. Adding cooling systems or heat exchangers also keeps temperatures under control.
Conclusion
Chemical processing comes with hidden challenges which if ignored can cause major setbacks in the production. However, investing in a high-quality centrifugal pump can solve most of these issues, ensuring smooth and efficient operations at all levels. Pumps like those from Fristam as mentioned above with their key features and adaptability, are not just tools but can prove to be an essential partner to combat all the chemical processing challenges like a pro. By addressing these potential hurdles actively, you can manage your operations and focus on delivering the best results.
FAQs
What is the working principle of centrifugal pump?
A centrifugal pump works by spinning a part called an impeller. As it spins, it pushes the liquid out, creating pressure that helps move the liquid through pipes.
How does a centrifugal well pump work?
A centrifugal well pump pulls water from the well by spinning an impeller. The spinning creates pressure that moves the water up through the pipes to the surface.
