Optimise your vacuum system with stainless steel vacuum fittings

When working with industrial-scale vacuum systems, the ability to maintain a constant negative pressure is crucial to your process stability and product quality. Whether you work in food production, chemical processes or pharmaceuticals, the connections in the system are the most critical point. By choosing the right stainless steel vacuum fittings, you ensure a tight and hygienic transition. This minimises the risk of leaks, reduces energy consumption and meets the industry's most stringent requirements. 

Vacuum fittings act as the components that connect pumps, pipes and containers in a closed system. Unlike pressure systems, where a small leak blows air out, a leak in a vacuum system will suck in impurities from outside. This makes tightness an important safety factor, as a faulty connection can lead to food contamination or unintended chemical reactions. 

In both the food and pharmaceutical industries, vacuum fittings are an important part of the overall system, where tightness and cleanliness have a direct impact on your product quality. 

Typical applications in the process industry: 

• Evaporation plants: Used for gentle concentration of milk and juice, among other things. 
• Degassing: Removal of oxygen from liquids to improve shelf life. 
• Vacuum transport: Efficient and closed transport of powders such as flour, sugar, medical preparations and additives. 

It is worth noting that other components such as valves also play an important role in vacuum systems, as they are good at regulating the flow of both liquids and powders under vacuum, while also being easy to maintain. 

Are you looking to optimise your vacuum system with a quick and flexible solution? Our comprehensive range of vacuum fittings, compliant with the KF standard (Klein Flange), is designed to allow you to assemble, modify and disassemble your process lines entirely without the use of tools. This offers you a significant advantage when it comes to frequent cleaning or ongoing changes in production.

To ensure full compatibility with your existing system, all components are developed in accordance with the international standards DIN 28403 and ISO 2861. They are manufactured from AISI 316L stainless steel and ensure stable operation right down to a high vacuum of 10⁻⁷ mbar.

Our range covers various piping requirements. You create the foundation with our flange, which ensures tight connections between pipes, valves and pumps. Our centering ring with gasket acts as the heart of the seal itself. This completely eliminates dead spaces and contamination in sanitary applications. You lock the entire joint mechanically with the robust clamping ring, where the practical wing nut allows you to close the system securely using just your hands.

When you need to adapt the pipework in confined spaces, our elbow (90°) handles compact changes in direction without slowing the flow at all. If you also need to connect different dimensions, our flange with concentric reduction ensures a smooth, conical transition directly within a single component. This saves both space and the need for extra clamps.

Expanding the system is just as straightforward. With a tee, you get a reliable, right-angled branch for pressure gauges or sensors, for example, whilst our tee with reduction, solves space constraints by integrating the size change directly into the branch itself. Should a port or pipe run remain unused, you can easily and airtightly seal it off with our robust blind flange. It acts as a secure dust cap in your process.

When choosing the optimal vacuum fittings, it is important to find the right balance between technical specifications and practical application in daily operations. It is important to choose components that not only fit physically, but also support the integrity and hygiene requirements of the entire system. You should assess whether your system works with rough, fine or high vacuum, as this dictates the requirements for the precision of the assemblies. 

We know that no two process plants are alike, which is why we offer technical support on optimising your vacuum line. If you need a specific solution or advice on material selection, you can always reach out to our team to ensure the best result.

KF stands for ‘Klein Flange’ and is the international standard for quick couplings for vacuum systems. Because our components comply with DIN 28403 and ISO 2861, you get full compatibility with your current equipment. This means that you can easily replace individual parts or expand the system without worrying about fit or leaks. 

In process environments with frequent cleaning and chemical exposure, choosing AISI 316L is the foundation for long service life and high operational reliability. This steel grade ensures optimal corrosion resistance against aggressive media. At the same time, you can be sure that your components meet the strictest hygiene requirements in food and pharmaceutical production.

Yes, the entire KF-solution is designed for manual handling. The combination of flanges, centre rings and rings with wing nuts enables your technicians to assemble and disassemble the vacuum points quickly and safely by hand. This is a significant advantage in production environments where you often need to disassemble equipment for cleaning or maintenance.
