Removing scale from Pumps & Pipes with Ultrasound

Limescale buildup is one of the most common and persistent problems across multiple industrial sectors. From heat exchangers and boilers to tanks, pipes, and cooling systems, limescale buildup is a constant threat to operational efficiency. Over time, this buildup reduces equipment performance, increases energy consumption, promotes premature component deterioration, and generates additional maintenance or replacement costs. Faced with this challenge, ultrasonic cleaning has emerged as a highly effective, precise, and sustainable solution for removing limescale noninvasively and with outstanding results.
 

What is limescale and why is it a problem?

Limescale is primarily composed of calcium carbonate (CaCO₃), a solid residue that forms when hard water—rich in minerals such as calcium and magnesium—circulates over hot metal surfaces or evaporates, leaving behind sediment. These scale deposits tend to adhere strongly to the internal surfaces of pipes, valves, heating elements, radiators, tanks, or heat exchanger plates.

Its accumulation reduces thermal efficiency, as calcium carbonate is a poor conductor of heat, forcing systems to consume more energy to maintain performance. Furthermore, in sectors such as the food, pharmaceutical, and chemical industries, the presence of scale can compromise the quality of the final product and pose risks of contamination.
















 

Ultrasonic Cleaning as an Effective Solution

Ultrasonic cleaning offers a revolutionary alternative for combating limescale deposits without resorting to aggressive mechanical methods or highly corrosive chemicals. Using high-frequency ultrasonic waves, this system generates a phenomenon called cavitation, through which microbubbles form and collapse in the cleaning fluid. This collapse releases energy in the form of microscopic impacts that directly attack the layers of encrusted limescale, removing them even in areas inaccessible with traditional methods.

One of the great advantages of this technology is that it acts uniformly over the entire submerged surface. This ensures that even areas with complex geometries, internal cavities, or narrow ducts are cleaned as effectively as flat or exposed areas. Unlike blasting, brushing, or chemical cleaning, there is no risk of mechanical wear, deformation, or damage to the base material.

Key advantages of ultrasonic cleaning against limescale

1. Deep removal even in inaccessible areas
Thanks to the cavitation phenomenon generated by ultrasonic waves, scale is removed not only from visible surfaces but also from internal areas, nooks and crannies, crevices, and complex geometries that traditional methods cannot effectively reach.

2. Preservation of the treated material
Unlike aggressive mechanical or chemical cleaning, ultrasound does not damage metal surfaces or alter the structural integrity of parts. This is essential for delicate components, precision sensors, or plate heat exchangers.

3. Reduction in maintenance time and costs
Ultrasonic cleaning cycles are faster and require less human intervention, resulting in significantly reduced downtime and lower operating costs.

4. Sustainability and Reduced Environmental Impact
Ultrasonic cleaning allows the use of biodegradable detergents at low temperatures, eliminating or drastically reducing the use of toxic chemicals. This not only protects the environment but also facilitates waste management and improves workplace safety.

5. Improved Operating Performance
The effective removal of limescale improves heat exchange, reduces energy consumption, and restores optimal operation to equipment such as boilers, cooling systems, and industrial tanks.

6. Compatibility with a Wide Range of Materials and Sectors
Ultrasonic systems are suitable for cleaning components made of stainless steel, aluminum, titanium, copper, or engineering plastics, making them suitable for industries such as food, pharmaceutical, chemical, energy, and marine.

7. Automation and Quality Control
Modern ultrasonic equipment, such as that developed by DCM Ultrasonic, features digital controls, frequency sensors, and automation options, allowing full control of the cleaning process and maintenance traceability.
