Meet Tjomi, our Pump Optimisation Whiz

When he’s not buried in a book or cheering on his favourite soccer team, mechanical engineer, Tjomi Shatika, is busy diving into pumping systems and figuring out how to make them more energy efficient. Since joining Lithon in 2020, Tjomi has become passionate about the world of pumping systems optimisation, focusing on variable frequency drives (VFDs). We chatted with Tjomi to get a better understanding of these concepts.


What is Pumping Systems Optimisation? 


In mechanical engineering, pumping systems are used to transport and circulate liquids or gases from one spot to another. They’re an essential component of water supply, heating and cooling systems, and other industrial processes, to name a few. 


Since pumping systems form such a crucial component of mechanical processes, it’s understandable that engineers focus their efforts on ensuring that they work efficiently and reliably.


To optimise a pumping system, an engineer finds ways to pump liquids or gases using less energy while improving the efficiency and dependability of the system. 


What is a Variable Frequency Drive (VFD)?


VFDs have revolutionised systems that rely on motors, such as pumps. They adjust the motor’s speed to match system requirements, resulting in energy savings and improved efficiency.


Tjomi’s Tips on How to Optimise Pumping Systems   

1. Avoid Pump Oversizing

Choose the right-sized pumps to match the requirements of the system. Oversized pumps consume more energy and can lead to inefficient operation.


2. Minimise Pipework Pressure Loss

Optimise the design and layout of the pipework to reduce pressure loss. Lower pressure loss results in reduced energy consumption and improved overall system performance.


3. Introduce VFDs

By adjusting the motor speed to the required flow rate, VFDs optimise energy consumption and prevent unnecessary energy waste.


4. Implement Efficient Control Systems

Smart control systems that regulate the operation of pumping systems are able to automatically adjust pump speed, optimise sequencing, and respond to varying demand conditions, leading to improved energy efficiency and performance overall.


5. Conduct Regular Maintenance

Regular maintenance is essential for the optimal performance of pumping systems as it helps identify and address any issues promptly, ensuring the system runs reliably and efficiently.
