O-Ring and Seal for Food and Drug Industry

The manufacturing and design of sealing components for the food and pharmaceutical industries has been the focus of GMORS since 1981. Our range of o-rings and seals match every type of application and equipment used in food processing and drug manufacturing.

GMORS provides advanced sealing components to major equipment manufacturers in the processing of food, life sciences and biochemical industries. Meeting the challenge set by the industries for greater hygiene standards for elastomeric sealing parts, GMORS offers o-rings and seals of superior performance formulated to withstand corrosive chemical media encountered during sterilization processes. Complying to standards set by USP Class VI, FDA 21 CFR 177.2600, 3A-Sanitary Standards and ADI (Animal Derived Ingredients) Stands, our elastomeric seals and parts resist the deleterious effects of various cleaning chemicals and active ingredients.

Seal Degradation and Food Contamination

Sterilization and cleaning of food processing equipment are done at high temperatures, and elastomeric seals are constantly exposed to extreme service conditions. Contamination of food during processing happens when damaged elastomeric sealing parts breaks off into fragments. Microbial growth thrive under conditions of surface deterioration of the o-rings and seals, and advance the degradation of the hygienic environment.

Performance Requirements for O-rings and Seals used in Food Manufacturing

1. Resistance to various chemicals found in food products.
2. Resistance to aggressive cleaning chemicals encountered in clean-in-place processes.
3. Surface of sealing components should not hinder effective sterilization and cleaning.
4. Resistance to wear and abrasion.
5. Non-toxicity of seal material.

Areas of Application

Centrifugal pumps, centrifuges, fittings and pipes, diaphragm and piston pumps, separators, homogenizers, decanters.

Compliance Standards

Full certification of products in accordance with international standards for compatibility for use in food and drug manufacturing equipment.

FDA 21 CFR 177.2600: This regulation of the Food and Drug Administration (FDA) stipulates the type and quantitative limits of ingredients found in elastomeric compounds that are used in the making of molded products for repeated use for all phases during food processing. This includes the preparing of food, its packaging as well as transportation.

3A-Sanitary Standards: The design of food and beverage equipment and that of the pharmaceutical industries based its criteria for standards of hygiene on 3A-Sanitary Standards. GMORS manufactures o-rings and seals in accordance to the standards of 3A-Sanitary Standards, which also conform to the guidelines of FDA CFR21.177.2600. Diseases causing agents from ADI (Animal Derived Ingredients) are excluded from getting into the food processing chain because our sealing products are ADI-free.

USP Class VI: The biocompatibility of products and equipment used in the food and drug, and health care industries must conform with USP Class VI in their manufacture. The strictest testing procedures apply in USP Class VI, which is the highest level within six classes under the USP protocols.

An extensive range of elastomeric materials is offered by GMORS that comply with the above mentioned standards. The range of materials offered include FKM, EPDM, Silicone, FFKM, HNBR, NBR and more.
