Application of mechanical seals in food and pharmaceutical industry

The food and pharmaceutical industries focusing on sterility in the preparation, production and packaging of food.

In these industrial sectors, in addition to appropriate technical specifications, seals used in the devices must have additional properties and requirements for cleanliness, health policy and legislation.

These properties include:

- compatibility with foodstuff;

- easily cleared, smooth and durable surfaces;

- possibility of sterilization and cleaning (SIP/CIP) of combined nodes, without their dismantling.

In the food industry are used in various devices which use mechanical seals.

If they come into contact with the food product, then they are subject to special requirements for hygiene, are just some of the devices:

- vacuum filters for mixers that prepare biomass;

- progressive cavity pumps (Allweiler, Netzsch), which are widely used for feeding and packaging;

- agglomerators, in which the crystals are transformed into micro-granules with good filling properties.

Hydraulic pump components used in the pharmaceutical and food industries, are typically made from sheet steel by deep-drawing technology. The additional electropolishing increases the quality of the surface treatment, which ensures easy cleaning.
