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.

Designing pumps, compressors and other equipment, the aim is to prevent leakage into that can emerge at any point by liquids or gases. To solve this problem very often are used mechanical seals. To obtain the desired sealing function and an adequate lifetime of the mechanical seal,the preconditions must be fulfilled within the permitted tolerances at any time: parallelism of the sealing surfaces perpendicularity of the seal faces to the rotation axis elastic contact of the sealing surfaces existence of a lubricating film between the two sealing surfaces Usually the sealing capability of the mechanical seal against shaft or housing is obtained with the secondary seals, as O-rings, bellows or boots In conjunction with the International Organization for Standardization (ISO) and their standards (ISO 3069), the German Industrial Standard (DIN) published proposals for standard mechanical seals with DIN EN 12756 (24960).

O - ring seal as flexible perfection To determine which O - ring can be used , only a few important operating parameters must be defined . The temperature , the pressure and the indication of the chemical resistance determines the selection of the correct O - ring at the right application. O - rings from Billi - seals are distinguished , depending on the material , by high thermal stability, good chemical resistance and good low temperature flexibility.

In order to be able to meet the individual requirements of our customers, we offer various types of spiral wound gaskets: For example, you can choose between standard versions with a smooth surface and various special models. All articles are based on a stainless steel strip and high-quality filling materials such as graphite and PTFE, which underlines the excellent quality standard. The spiral wound gaskets of billi are characterized by a constant elasticity during hot-cold cycles. Classical applications in the chemical industry include all types of gas lines, directional valves and pumps. Furthermore, spiral wound gaskets are the optimal solutions for pressure vessel openings in steam systems as well as low and high pressure in nuclear power plants. For the best possible functionality of spiral wound gaskets, the careful considered choice of model is of central importance: the versions with centering ring, for example, assures an ideal fit between the bolts.

The range in the graphite seals segment is not limited to rings and tapes, but also includes sheets: The many advantages of billi graphite sheets include the low permeability of liquids and gases as well as high resistance to chemical substances. In addition, the plates made of natural graphite convince for their enormous stability and high resistance to temperature fluctuations. The graphite sheets can be ordered in different versions so that the perfect items are available for every application: For example, you can choose from models without steel reinforcement, with plain steel inserts and tanged stainless steel reinforcement. All graphite gaskets from our company are convenient for the targeted interaction between a high quality standard and improved health protection: you can order asbestos-free graphite sheets and many other types directly from us at a reasonable price.

The function of gaskets is to prevent the leakage of medium outside the equipment. Static seals are used in many applications such as plumbing and heating systems, sealing fasteners, containers and pipeline construction. They are washers, rings or frames which generally are adapted to the whole width of the sealing surface. They can be used for example in flange connections of pipelines, pumps, motors, valves, etc. The gaskets are made of various materials such as: Rubbers, fiber plates, synthetic plates, graphite, PTFE, etc.

Suitable for reapplication of a nurturing protective coat on vinyl floors after an intensive cleaning with an appropriate detergent. Vinyl Refresher is a glossy care product based on acrylates. Scratches are laminated, the surface is at once nurtured, protected and sealed. Vinyl Refresher is applied after transfer or intensive cleaning as preventive care or to renew the floor.

Based on decades of experience, GMN has specialized in producing extremely high quality machine tool components. Through this strategy, GMN manufactures a wide range of standard non-contact seals and customized solutions. The frictionless, no-wear characteristics of GMN non-contact seals offer effective, economical and ecological solutions for modern applications in and outside of the machine tool industry. Thanks to the non-contact design of the inner and outer ring, GMN labyrinth seals guarantee completely frictionless operation and therefore offer a wide range of benefits for a whole host of applications and uses.

Metallic materials of the seal components of GMN labyrinth metal seals - series L/M - guarantee highest resistance against coarse and fine contamination.

The corrosion-free material properties mean that the non-contact GMN plastic seals - series S/SA - are particularly well-suited for protecting from watery liquids. Polyoxymethylene has a high resistance to a variety of acids (lactic acids), chemicals and fungi. GMN non-contact plastic seals are approved for the food industry.

Particular Challenges: The seal surfaces in this case are made of very glossy metal, with the drawback of emitted reflections. This effect during an optical measurement must be eliminated. Furthermore, it is absolutely necessary to guide the laser scanner on a linear path over the surface, since fluctuations of distance may falsify the measurement result. QuellTech Solution: The Quelltech model Q5 disposes of an adequate resolution in X and Z direction and proves to be able to verify the planarity tolerances and to measure the size of defects. Meanwhile a precise rotary axle, used as guiding element, moves the scanner over the surface to be evaluated. Interfering artefacts caused by the glossy finish are suppressed by particular algorithms integrated within the software. As an encoder value is permanently supplied by the rotary axle, the position of each scanner profile within the point cloud can accurately be determined.

Side seal bags are practical, universal bags for just about anything that is light and not too bulky. At Dürrbeck, specialists in custom plastic bags and film, we produce side seal bags from high-quality raw materials made to order for a wide range of industries and uses. We place great importance on first-class manufacturing. With side seal bags, our focus is on especially sturdy seals that, as the name suggests, are located on the left and right sides of the bag. Side seal bags have a maximum thickness of 0.15 mm; the bottom of the bag is closed.

High-quality blown film forms the basis for Dürrbeck’s tailor-made packaging solutions. Depending on the size, weight and volume of the goods to be packaged, the bottom seal bag and the flat bag are among the most popular types of packaging. Universal plastic bags for various purposes, they are ideal for storing and protecting pharmaceuticals, food, small electrical parts or building materials and textiles against dust, dirt or the elements. Our bottom seal bags are made for smaller-sized contents, flat bags for bulky and heavy items (from 400 x 600 mm). Bottom seal bags and flat plastic bags are easily manufactured plastic bags made of polyethylene (LDPE, HDPE, MDPE) – without side gussets, closures or the like. This type of packaging offers excellent protection and is an attractive, effective way to present your products.
