Targeted solutions for challenging tasks

From engineering to commissioning, we supply feeding systems based on all known drive components – from vibration conveyors to step conveyors.

Correct component positioning is our business.

Our machines and services are of recognised high quality, and have made us one of the most important companies worldwide in the field of feeding systems. Our core expertise lies in pharmaceutical versions of the feeding systems, including versions for clean rooms, whereby we can manufacture entire customised feeding systems in accordance with requirements. We use our knowledge and craftsmanship to develop and supply cost-effective and reliable feeding systems. Together with our parent company and partners, we offer a global network of top-performing contact partners to our customers.

PSA feeding systems

Our history

PSA was established in 2011 as a subsidiary of RNA GmbH. RNA is a company which was established on the market in 1972, and in the 50 years since this time it has become one of the world’s biggest and most important suppliers of vibration transport systems. Feeding systems for all kinds of industries are manufactured in Germany (8 locations), Switzerland, England and Spain by a total of around 400 employees

The systems made by PSA were added to the RNA product range in 2011. PSA is the authority for pharmaceutical systems. Top quality vibratory sorting bowls are manufactured by a powerful team at the Wolpertshausen location, whereby it is always ensured that customer requirements are met in their entirety. Electropolished surfaces with roughness depth of 0.4μ can be achieved, and it is ensured that the material is consistently traceable. Of course, standard versions can also be ordered.

Quality has top priority at PSA, as it does throughout the group of companies. This is ensured by having highly trained employees and consistent implementation of the QM system. Of course, this includes detailed specifications and an independent department which checks every component prior to delivery. The machine functions are simulated using appropriate devices in order to carry out realistic testing.

Yours, Fritz Kraft & Benedict Borggreve
