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. 

We offer a complete solution consisting of three products designed to work together as a single unit. All products in our range are made of AISI 316 stainless steel. This ensures optimal corrosion resistance and a long service life, even in demanding environments. The products are developed according to the KF standard (Klein Flange) and comply with the international standards DIN 28403 and ISO 2861. This guarantees full compatibility with your existing equipment. 

Our vacuum flange are the ideal solution for vacuum-tight connections between pipes, valves, pumps and vacuum chambers. Designed as a quick-connect flange, it allows connections to be assembled and disassembled manually without the use of tools. This is a major advantage in systems with frequent maintenance or ongoing changes in the setup. The flanges are suitable for use in everything from low to high vacuum and are available in several dimensions, so they can be easily integrated into most existing systems.  

The vacuum clamping ring is the component that holds the system together and ensures a reliable seal under negative pressure. The ring is equipped with a practical wing nut that enables quick and secure closure without the use of special tools. The robust construction ensures that the component retains its functionality over time, even in environments with frequent cleaning and chemical exposure from the production environment. 

The vacuum centring ring acts as the heart of the seal between two flanges. The precise design of the ring ensures that the gasket sits correctly in the flange groove, avoiding dead areas where bacteria or media residues could otherwise accumulate. The product is particularly valuable in sanitary applications where cleanliness is a top priority and where you want to eliminate any risk of contamination.

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.
