Ceramic Components for Industry Pumps
During fluid transport in industrial and hygienic environment both the pump unit as well as handling components, such as pipes and valves can also be exposed to high stress and are therefore subject to wear and corrosion.
Advanced Ceramics instead of Metal or Plastic
Due to their specific properties such as hardness, toughness, chemical or temperature resistance, depending on the application, ceramic solutions can significantly contribute to reducing or even neutralizing wear effects.
Thus, compared to other materials such as metal or plastic, ceramics opens up enormous performance potentials and can help achieving application specific competitive advantages based on comprehensive material expertise and application know-how.
Ceramic Solutions for Better Industry Pumps
In demanding industry environment, advanced ceramic solutions from CeramTec set standards for process reliability and performance. We have developed gliding, bearing, sealing and control technology with high performance ceramics – with outstanding tribological, chemical and physical properties. This allows highly strained components in pumps, valves, machines and systems to run reliably, with high economic efficiency and low wear, even under extreme operating conditions.
For each application and each requirements profile – from micro-dosing pumps in medical technology to large power plant pumps – together with you we develop individual solutions based on optimum selection and material setup as well as customized component design.
Ceramics as a sustainable lead-free option
According to The Restriction of Hazardous Substances Directive 2002/95/EC (ROHS) using the lead-containing metals (like brass, lead-based bearing alloys,lead-tin alloys, etc.) is to be limited.
Ceramics, as non-lead high performance material is a perfect alternative for many applications, where amount of lead needs to be reduced.
FAQ - Ceramic Components for Pumps, Valves & Seals
Why are technical ceramics suitable for pumps and valves?
In demanding industrial environments, CeramTec’s advanced ceramic solutions set standards for process reliability and performance. We have developed sliding, bearing, sealing, and control technologies using high-performance ceramics – with outstanding tribological, chemical, and physical properties. This enables the reliable, durable, cost-effective, and low-wear operation of highly stressed components in pumps, valves, machines, and systems, even under extreme operating conditions.
Which materials does CeramTec use for seals and pump components?
CeramTec uses high-performance ceramics such as aluminum oxide, zirconium oxide, silicon carbide, and silicon nitride. These materials deliver excellent results – both in terms of durability and reliability in aggressive media.
For which applications are CeramTec components in pumps and valves suitable?
They are used in the chemical, petrochemical, and pharmaceutical industries, oil and gas, refineries, food processing, energy, water treatment, and many other sectors. The components impress with outstanding tribological, acid-resistant, and physical properties.
How does CeramTec support its customers in selecting components?
For every application and requirement profile – from micro-dosing pumps in medical technology to large power plant pumps – we develop customized solutions together with you, based on optimal material selection and configuration as well as customer-specific component design.
How do the materials differ in terms of wear resistance and temperature resistance?
The harder the material, the higher its wear resistance. Therefore, SiC materials exhibit the best wear properties.
Temperature resistance primarily depends on the presence of glass or metal phases in the ceramic. Their softening behavior determines temperature resistance. Accordingly, silicon carbide has comparatively very high temperature resistance.
How corrosion-resistant are the ceramics against specific chemicals?
In general, ceramics have significantly higher corrosion resistance than metals. This also applies to resistance against chemicals. In principle, non-oxide ceramics have higher resistance compared to oxide ceramics. Furthermore, oxide ceramics show better resistance to acids than to alkaline solutions.
What advantages do ceramic components offer compared to metal or plastic?
Today, metals and plastics often no longer meet the steadily increasing material requirements of a wide range of applications. Ceramics benefit from their excellent material properties in terms of mechanical, thermal, electrical, and chemical resistance. This has positive effects when maintenance and repair costs must be reduced for commercial or technical reasons, and the focus is therefore placed on long-lasting components.
Do the ceramics comply with specific standards (e.g., ISO, …)?
Ceramic materials and their properties are defined in various ASTM and DIN ISO standards. In addition, various CeramTec ceramics are suitable and certified for applications involving contact with drinking water and food. Furthermore, some of the materials used are also biocompatible, enabling their use in a wide range of medical applications.
