GYLON BIO-LINE® / GYLON BIO-LINE® PLUS – Quality seals for pharmaceutical industry

Pharmaceutical and food processing industries strive to limit and avoid operational down time, caused due to cleaning and maintenance procedures. Sterilization cycles are carried out in the shortest possible time with highly concentrated chemicals, high temperatures and increased flow rates. Exposed to these conditions elastomeric seals failure due to exceeding their limits, thus resulting in short exchange intervals. GYLON BIO-LINE® and GYLON BIO-LINE® PLUS offer approved sealing materials for high temperatures and demanding processes – while at the same time entirely compliant to all major pharma regulations.

Key Benefits

• High dimensional stability
• Stopped cold flow
• No intrusion/recession
• No gap extrusion
• Excellent chemical resistance**
• Masters all CIP- and SIP-cleaning processes
• Excellent cleanability of gasket
• Wide temperature range
• High pressure & vaccum duties

PS-SEAL® – many different lip materials and configurations.

The PS-SEAL® product line stands for reliable sealing of rotating shafts at high circumferential speed, high pressure and extreme temperatures. Abrasive media is sealed as good as aggressive media. Usual radial shaft seals are only partially or even not usable at all under these conditions, as their seal lips are made of elastomeric materials.

PS-SEAL®s are usable in many different applications and can also be an alternative to mechanical seals and braided packings. The product line PS-SEAL® offers cost-effective and practical solutions to a wide range of applications. The portfolio of Garlock shaft seals offers standardized as well as special customized seals.

The high performance seals PS-SEAL® work with a sealing lip made of GYLON® or other modified PTFEs. Garlock produces GYLON® in a process that has been specially developed.

PS-SEAL® Non-Standard – different lip materials

The Garlock PS-SEAL® Standard with a GYLON® Black lip and the static seal made of FKM has long been known in industry as a proven sealing element in critical sealing situations.

But what is the solution at temperatures above 200°C, which FKM cannot withstand? Or in an application with dry running? Or in case of food conformity requirements according to FDA or EC regulation 1935/2004? Or in use as a seal against abrasive substances? Or or or….

The ideal solution for these cases: The Garlock PS-SEAL® Non-Standard, which can be flexibly adapted to the critical application parameters. With the Garlock PS-SEAL® Non-Standard, for example, the GYLON® lip materials can be varied accordingly to meet demanding requirements for circumferential speed and pressure stability. And this is possible in both wet and dry running.

Conveniently, the different GYLON® lip materials are already visually recognizable due to the lip color.

Material MS Grey

A material developed with the hardest glass that scores excellently with abrasive media even without a GYLON® matrix. Optimal for dry running in the environment of abrasive powders and dusts. It also offers high pressure resistance with low wear. It is often combined in tandem with the other lip materials to increase its performance with low-viscosity media or gases.

PS-SEAL® Non-Standard – different lip configurations

The Garlock PS-SEAL^® Standard is a PTFE-based high-performance seal that meets a wide range of requirements in practical use.

In some applications, however, the successful PS-SEAL^® Standard proved not to be completely suitable. That’s why a team of Garlock experts developed additional designs: The PS-SEAL^® Non-Standard.

With the PS-SEAL^® Non-Standard, a range of variants is available. The variants are for application areas that require special configurations, since lip material and lip layout can be varied as desired.

The Garlock PS-SEAL^® Non-Standard is known for reliable sealing of rotating shafts at high circumferential speeds, high pressures, and extreme temperatures from -90° to +260°C. The wide range of lip materials and layouts means the PS-SEAL^® Non-Standard gives excellent sealing in difficult applications. The PS-SEAL^® Non-Standard can handle PxV (Pressure x Velocity) of 45 bar.m/s for lubricated applications and 15 bar.m/s for dry running.

Furthermore, with the PS-SEAL^® Non-Standard, Garlock offers a solution that fits into the small installation spaces of conventional shaft seals. Should none of the possible special configurations of PS-SEAL^® Non-Standard prove to be suitable, the PS-SEAL^® Special is available, with which almost all desired requirements can be achieved.

Be it several lips in a row, lips for media separation or a design with back to back lips – the PS-SEAL^® Non-Standard offers a wide range of configuration options. In particular, the PS-SEAL^® Non-Standard design with reverse lip is frequently used, and highly valued, in the food and pharmaceutical sectors.

Tandem

Two seal lips towards the media.

If longer service life is required or if even greater plant safety is desired, a PS-SEAL® Non-Standard Tandem is a good choice. With the smallest installation width, two seal lips are now available instead of just one.
