The Challenge

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.

New Sealing Material HiFluor® FB for Hygienically Sensitive Applications

HiFluor® FB - Hygienically Sensitive Sealing MaterialBe it in the production of food, pharmaceuticals and cosmetics or medical devices coming into contact with the human body, excellent purity and media resistance combined with a wide range of robust properties is always required of the materials used for the components in the manufacturing processes. Specifically for these challenging applications, Parker has developed a new sealing compound with very good mechanical properties and excellent permanent elasticity: HiFluor® FB V8991.

Fluoroelastomeric materials have proven their viability in chemical and food processing, cosmetics, pharmaceutical and life science applications involving non-polar solvents, aliphatic compounds, greases, oils and aromatic substances whenever the resistance of standard materials such as hydrogenated nitrile butadiene rubber (HNBR) and ethylene propylene rubber (EPDM) is no longer sufficient.

Innovative “Pure” Sealing Solution HiFluor® FB V8991

As a compound and seal manufacturer, Parker Prädifa, in the light of the growing demands made on sealing elements in the aforementioned markets, has developed a HiFluor® FB compound with very good mechanical properties and excellent permanent elasticity.

A Guide to Selecting the Proper Sealing Material for Food Applications

Food ApplicationsThe substances used in the food and in the chemical process industries are identical in many cases, whether they are of natural origin or synthetically produced.  Irrespective of their type and occurrence – be it in process media, in raw materials for products or in finished products – the materials for seals and engineered components used in production equipment coming into contact with diverse chemical substances have to meet specific purity requirements and be resistant to chemicals under the given process conditions. Purity and stability are therefore basic prerequisites for materials in the chemical process industry and the food industry. The challenge lies in selecting the proper sealing material for an application.

Top Priorities: Consumer Health and Safety

Consumer health and safety are of paramount importance in food, beverage and pharmaceutical production processes. Therefore, the materials have to comply with specific legal requirements and standards, depending on their application. The harmlessness of the materials for the intended uses, such as applications involving contact with foodstuffs and drinking water, must have been certified by relevant approvals and conformities. Equally important to consumer safety is that the materials are free of polycyclic aromatic hydrocarbons (PAH), phthalates, mineral oil based plasticizers and animal derived ingredients (ADI).
