Pharmaceutical industry

In a branch with such high hygienic standards as the pharmaceutical industry, production is subject to increased requirements for cleanliness and purity. That means, among other things, that only selected materials which have been approved for this purpose may be used for transport and conveying tasks. For example, the belts installed in the plant must be resistant to corrosion, abrasion, acids, and easy to clean.

As experts in special timing belts, we have the appropriate solution for every requirement in stock. Within the pharmaceutical industry, Alphabelt uses special materials that are certified for direct contact with foodstuffs in accordance to European and American standards. We are pleased to develop a special solution together with our customers that is optimized precisely to the respective requirement profile.

Examples of special Alphabelt features for the pharmaceutical industry:

Easy to clean

Timing belts that are in contact with pharmaceutical products must be easy and thorough to clean. To avoid poorly accessible spots where dirt and moisture could accumulate, we use belts with closed lateral edges. In these applications, we also dispense with the winding nose, a groove in the base of the tooth that would promote contamination and corrosion, which is otherwise common in timing belts. In addition, coatings can be applied endlessly, i.e., without seams and splices.

Enhanced corrosion protection

JDepending on the substances to which the belts are exposed, there is often a need for materials and designs that are particularly acid-resistant and protected against corrosion. Unlike standard timing belts, the steel cords are completely enclosed by the belt body, which is usually made of PU. This allows the belts without any problems to be used in humid environments and without the cords coming into contact with moisture or acids.

Resistant to cleaning agents

Agents applied to the belts for cleaning and disinfection are highly corrosive to conventional PU materials. Particularly developed special polyurethanes provide increased resistance to cleaning agents. They also have improved resistance to hydrolysis.

Low abrasion

UIn order to produce and transport pharmaceuticals in the cleanest possible conditions, extremely low abrasion of the system components is required. When selecting belt materials for the pharmaceutical sector, Alphabelt therefore relies on high-quality, wear-resistant materials.

Antistatic coatings

To protect against any unnecessary contamination, the use of antistatic coatings is advantageous, as they significantly reduce the adhesion of dust.

Legal requirements

For the production of belts used in the pharmaceutical industry, we only consider selected materials approved for contact with pharmaceutical products. All materials used here are certified according to the regulations EU 1935 / 2004, EU 10 / 2011, EU 174 / 2015 as well as according to FDA and thus meet both European and American standards. Of course, a declaration of conformity for materials qualified for pharmaceutical use is available.

Appropriate joints

Although the subsequent joining of the timing belt ends should be avoided as far as possible so as not to create unnecessary spaces in which contamination can accumulate, in practice this is unavoidable in certain circumstances. In such cases, it is important that the connection is made with materials compatible with pharmaceutical applications. Suitable are, for example, Pin Joint connections where pins made of stainless steel hold the belt ends together.
