Corrosion Protection

Great demands

Cleaning procedures with highly effective wash down agents are constantly being extended and place higher and higher demands on hygienic design and corrosion resistance.

According to the standards for the food, chemical and pharmaceutical industry, intensive, strict wash down and disinfection processes are required.

To prevent cleaning and disinfection agents deteriorating the material, design and coating of machines for such applications have to be smooth and ensure optimum cleanability for manual or automated cleaning cycles.

NORD DRIVESYSTEMS introduced new solutions (regarding materials, treatment and machining) for the surfaces of motors, gear units, and components and offers an endurance kit providing an enormous degree of resistance against acids and alkalis typically used for cleaning in the food, chemical and pharmaceutical industries.

This is how it works

Modern gear units must be robust, compact, powerful, economical and lightweight. The advantage of aluminium is its low weight because weight is a cost factor, especially if the gear unit itself is a load that has to be moved as part of an automated positioning system. For this reason, aluminium alloy has become the preferred material for gear unit housings in many fields.

NORD DRIVESYSTEMS improves many of the optimum properties that an aluminium alloy offers for NORD gear unit housings. The material also has some inherent corrosion resistance and does not need to be additionally protected in all cases. At the very least, aluminium housings conduct heat more efficiently than cast iron. The resulting low operating temperatures have an advantageous effect on the internal gear unit construction and allow a longer service life.
