KSB Introduces Advanced Carbon Coating to Enhance Pump Durability

In July 2026, KSB Group launched NoriResist, which is a carbon-based high-performance coating that is designed to enhance the durability, efficiency, and sustainability of pumps and valves that are operating in harsh industrial environments. The company developed the diamond-like carbon (DLC) coating through close collaborative efforts between its research teams, application technology specialists, and industry partners. Primarily targeted at wastewater treatment and process engineering applications, NoriResist offers a robust solution for components exposed to abrasive and corrosive media.

KSB can now apply this coating to several hydraulic components, including impellers, wear plates, discharge covers, casing wear rings, impeller wear rings, and casings of close-coupled pumps. In addition to that, it is also compatible with grey cast iron, nodular cast iron, and steel materials, while selected plastic components can also receive the coating. The coating achieves a hardness of 4000-8000 HV (40-80 GPa), which makes it highly resistant to abrasive wear. It is also able to perform particularly well in fluids containing sand and other solid particles that typically accelerate component erosion.

Field trials conducted in heavily contaminated wastewater applications demonstrated that NoriResist maintained both surface quality and hydraulic efficiency even after going through thousands of operating hours. By contrast, conventional coatings showed noticeable wear and experienced a measurable decline in efficiency during the same operating period. This new advanced coating helps components retain their original contours and sharp vane edges, thereby reducing flow separation and minimizing efficiency losses.

Beyond performance improvements, KSB designed NoriResist by keeping the aspect of sustainability in mind. This coating is recyclable and also helps avoid the release of plastic and heavy metal particles into the environment. As reported by worldpumps.com, longer maintenance intervals and reduced spare-parts consumption can lower resource use and decrease overall pump life cycle costs, making the technology attractive for operators seeking both operational and environmental benefits.

Impact on the Chemical Market

Carbon-based materials are significantly popular in today’s day and age due to their capability to increase the surface of medium-to-heavy load-bearing as well as wear parts, by improving materials properties with elevated wear resistance, corrosion resistance, and less friction. Furthermore, carbon-based coatings adhere to minimal protein and have better compatibility because of the repelling capability of the surface.

Carbon-based coatings are used for a wide range of applications, including aerospace, automotive, electronics, energy, biomedical engineering, and industrial manufacturing. These coatings offer unique properties such as high hardness, wear resistance, low friction, and biocompatibility, thus making them an attractive choice for enhancing the efficiency, durability, and performance of different components and devices. There are several methods of synthesizing carbon-based coatings, including physical vapor deposition, chemical vapor deposition, and plasma-enhanced chemical vapor deposition, each having its own advantages and limitations.

Researchers continue to explore novel synthesis methods that can overcome these limitations and optimize the properties of carbon-based coatings. The applications of carbon-based coatings in different fields are rapidly expanding, with ongoing research and development in areas such as energy storage, sensing, and agriculture.

Impact on the Fluoroalkyl-based Coatings Market

The global fluoroalkyl-based coatings market size was calculated at USD 1.88 billion in 2025 and is predicted to increase from USD 2.01 billion in 2026 to approximately USD 3.78 billion by 2035, expanding at a CAGR of 7.24% from 2025 to 2035.

According to Precedence Research, the market is driven by rising demand for stain-resistant, weatherproof surfaces and expanding applications across construction, electronics, and automotive sectors. Correlations of miniaturization and high-performance requirements in the electrical field need low-energy coating thickness and chemical resistance. The high utilization in semiconductors, displays, and circuit boards makes them reliable, particularly in 5G and high-speed computing devices, leading to market growth.

The demand for low-VOC and waterborne fluoropolymer systems is especially evident in fields like aerospace, chemical processing, and food equipment production, where the standards of safety and performance are considered to be of prime concern. Increase in offshore wind power, manufacture of electric vehicles (EVs), and lithium-ion battery gigafactories further exceed the demand for advanced fluoropolymer coatings with chemical resistance, durability, and thermal stability.
