SEALS FOR PHARMACEUTICAL/FOOD & BEVERAGE PRODUCTION
Stein Industrial’s mechanical seal assemblies are essential to the production of pharmaceuticals and products for the food and beverage industry. These seals must withstand extreme temperatures and caustic and abrasive chemicals while complying with strict government regulations.
A custom-built Stein seal is guaranteed to meet all your specifications while adhering to the most stringent requirements for sanitation and hygiene. These include Clean in Place (CIP), Steam In Place (SIP), Washdown, and other processes designated by the National Sanitation Foundation (NSF).
Our high-performance mechanical carbon seals for pharmaceutical, food and beverage production include:
Mechanical seals are installed between an industrial agitator’s rotating and stationary components or mixer to minimize leakage. These agitator seals can perform under extreme conditions inherent to many industrial processes.
Stein’s custom-engineered barrier seals are field proven, and with over 30 years of experience, these seals are readily available to meet the stringent and demanding requirements of today’s turbomachinery industry.
Stein cartridge seals are quickly installed and easily removed from the pump shaft for maintenance, repairs or replacement. They are pre-built to include gland, sleeve, and other necessary seal system components into a single assembly.
Split-cartridge mechanical seals are an innovative solution for challenging applications involving turbines, compressors, and other rotating equipment when conventional mechanical seals may not be practical.
Mechanical seals used to manufacture products for human consumption must prevent external contamination at every stage of production. They must also be constructed entirely of materials that can come in direct contact with ingredients without affecting them.
Stein’s seals for food/pharma fulfill all these requirements. They are valued by manufacturers and the OEMs who build processing equipment such as HPLCs, batch reactors, centrifuges, autoclaves, and more.
Stein Seal Industrial makes many sealing products for pharmaceutical and food processing, including:
- Flame gaskets
- Perfluoro elastomer O-rings
- Sanitary gaskets
- Teflon pharmaceutical seals
WHAT THEY’RE MADE OF
Our custom seals for pharmaceutical, food & beverage production offer long life and unsurpassed reliability. We build them from the highest quality consumption-grade materials, including carbon, carbon graphite, silicon carbide, tungsten carbide, EPDM, HNBR, fluoroelastomers, perfluoro elastomers, stainless steel, duplex steel, and others.
Our carbon-graphite seals are ideal for food/pharma for several important reasons:
- Impervious to fluid intrusion
- Anti-bacterial properties
- Chemically resistant
- FDA-approved as GRAS (generally recognized as safe) for food processing
- NSF-51 listed
- Pharmacopeia Class VI–approved
