Material certifications, seal geometry and even seal color must also be factored in to allow for maximized seal life, minimized risk and reduced total cost of ownership for both the seal and the rotating equipment.
The most challenging operational environments for sealing mixers, agitators and pumps are often found in the food and pharmaceutical industries. When designing, selecting, or implementing a dynamic seal into operation in the food and pharma space, it is crucial to consider all the physical challenges the seal may face to ensure sealing success. Further, material certifications, seal geometry, and even seal color must also be factored in to allow for maximized seal life, minimized risk and reduced total cost of ownership for both the seal and the rotating equipment.
In this article, we will highlight some of the common environments found within these industries, discuss how the operating conditions affect seal design and selection, and finally, share some

Precision O-rings are manufactured by vulcanization in a closed mold using compression or injection molding. This makes it possible to produce O-rings in relatively small manufacturing tolerances and with good surface quality according to ISO 3601-1 and ISO 3601-3. Due to defined vulcanization parameters, precision O-rings
GYLON® BIO-PRO® seals provide a safe and durable solution for protecting the integrity of food and pharmaceutical processing media. Its modified and restructured PTFE material is pre-formed and stress controlled for all standard TRI-CLAMP connections. It is dimensionally stable and resists intrusion.

Pharmaceutical OEM - Autoclaves and Sterilizers
Since 1949, DeLama S.p.A. has grown to become one of the most well-known and qualified manufacturers of sterilization equipment, supplying major customers all over the world from its base in Italy. DeLama’s design and construction standards usually exceed the customers’ equipment requirements with the main purpose to protect their investments in critical industries such as pharmaceutical, Bio-Processing, Medical Devices and Food Production.
Hilge-Pumpen AG, Swiss subsidiary of Philipp-Hilge GmbH, Bodenheim, Germany, selected Kalrez® 6221 perfluoroelastomer parts to seal its Euro-Hygia®, Hygiana-HT and Contra pump series, to meet the stringent safety, cleanliness and sterilization requirements demanded by the pharmaceutical, biotechnology and cosmetics industries.
Pumps used in pharmaceutical, biotechnological and sterile processes are subject to some of the highest standards and safety requirements worldwide. In addition to ease of operation they must also provide maximum biological safety without any unfavorable hydraulic characteristics that could adversely influence sensitive products.
