Due to the wide range of different designs, perfectly suitable PTFE seals are available for every application. The PTFE gaskets from billi are characterized by high dielectric strength, excellent electrical insulation properties and a low thermal conductivity. All items are manufactured with a high processing quality. Discover the various PTFE gaskets in our online catalogue and order the right products for your application directly from billi. Depending on the respective requirements, different PTFE seals are suitable for you: Our comprehensive range includes, for example, PTFE thread sealing tapes with a temperature resistance of -200°C up to +260°C. The PTFE tapes are both, odourless and insoluble. In addition, the PTFE thread sealing tapes have a particularly low coefficient of friction, which improves their performances. We also offer PTFE cord with a pressure resistance of up to 10 bar. Possible applications include valves as well as piston and centrifugal pumps.

We develop and manufacture special seals for power stations, for the chemical and petrochemical industries, for machinery and pipeline construction. In other words, seals that provide the greatest possible reliability even under extreme operating conditions (pressure, heat, cold, aggressive media) – at temperatures from -200 to +1.000 °C. Product Range: - DVGW tested, see separate brochure - Punched, cut seals - Plates, foils - Semi-finished items - Form articles Benefits: - Highest chemical resistance - Insoluble and does not swell in organic or anorganic solvents - Resistant to the weather - Temperature range -190 to +250 °C - Highly anti-adhesive, does not stick - Resistant to hydrolysis Common fillers: - Quartz - Glass - Carbon / Graphite - Bronze - or without filters Fillers reduce the cold flow, lead to higher resistance to temperature and media, improve thermal conductivity and increase resistance to abrasion and pressure levels.

Barrel pump made of stainless steel with discharge tube. The Bürkle barrel pump made of stainless steel AISI 304 (1.4301) is suitable for filling combustible and easily flammable liquids. The barrel pump can conduct electricity and therefore fulfills the requirements for handling flammable liquids in combination with the accessory antistatic set. The PTFE gaskets ensure long-term and maintenance-free use. Pumping capacity approx. 9–22 l/min, dependent on pump length. The wide range of accessories makes it possible to adapt the pump to very different requirements.
