Ceramic Pumps  Manufacturers, Traders, Suppliers

WITTE offers pumps for applications in borderline areas. We develop durable, standardised or customised solutions of the highest precision. For more than 35 years WITTE has specialised in the development of gear pumps for industrial applications. It is our endeavour to always guarantee the customer the highest level of process reliability and to match the pumps exactly to the application and the process. In this way we guarantee the best efficiency and durability of our pumps. Reduced maintenance costs and intervals due to matched material pairings guarantee a fast payback the investment costs. We have been working successfully for many years with well-known companies and innovation drivers from the industry and are constantly developing new solutions. Should we not have the right solution at hand, we develop together with our customers the suitable product. We accompany our customers during the entire project from the prototype to the final product. Experts from sales, project management and design form the project and development team and keep us informed of the project status at all times. More than 35 years of experience and the knowledge of our competence team flow into each of our pumps.

Ceramic pumps and valves are engineered for high durability, featuring excellent wear resistance, chemical inertness, and thermal stability. Made from advanced ceramics like alumina or zirconia, they offer superior hardness, low friction, and minimal thermal expansion. These properties enable precise fluid handling and extended service life, even under harsh conditions.
With high corrosion resistance, they can handle aggressive chemicals and abrasive particles without degradation. While ceramics are brittle compared to metals, their performance in demanding environments outweighs this limitation. Ceramic pumps and valves are ideal for achieving reliability, efficiency, and longevity in critical fluid systems.

Applications of Ceramic Pumps and Valves
Ceramic pumps and valves are used in industries requiring precision, durability, and resistance to harsh environments. Key applications include:
1. Chemical Industry
Handling corrosive fluids, acids, and alkalis.
Precision dosing for aggressive chemicals.
2. Water Treatment
Managing abrasive slurries in desalination and filtration systems.
Pumping and controlling high-purity or contaminated water.
3. Pharmaceutical Industry
Hygienic pumps for liquid medicines and solvents.
Valves in sterile environments to ensure product integrity.
4. Oil and Gas
Controlling high-pressure fluids in drilling and refining processes.
5. Food and Beverage
Safe handling of liquids and slurries without contamination.
6. Power Generation
Used in cooling systems, nuclear reactors, and renewable energy processes.
