In heavy duty applications, leak free performance and high service life cannot be assured by a single sealing element; therefore, specially developed ”system seals” are arranged in series, building a ”tandem configuration”. Each sealing element in a system has its specific function and their interaction needs to be secured to get a redundant sealing system. The primary seal in Zurcon® material has an excellent wear and extrusion resistance under extreme working conditions. It allows a fine lubrication film passing this first barrier, ensuring the necessary lubrication of the secondary sealing element for long service life. The ”tandem arrangement” requires an outstanding back-pumping ability of the primary seal and the secondary seal, if a double acting scraper is installed.

A single-acting rod seal, Zurcon® L-Cup® is an alternative to the U-Cup. It is a highly effective sealing system offering optimized sealing performance and extended service life. With exceptionally low friction properties, it has high wear resistance, back pumping ability along with high static and dynamic tightness.

The POLYPAC® - Balsele is a compact rod seal consisting of an elastomeric sealing element and an integrated fabric reinforced base. Due to the radial pre-load an excellent sealing performance will be achieved even at low pressures. The fabric reinforced base prevents the seal from extrusion.

POLYPAC® - Veepac is a set of fabric reinforced Chevron rings comprising of a support ring , sealing rings and a pressure energising ring . In the packing set the energising axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the rod surface. Additional to the standard material special material grades are available for a large variety of working conditions.

Double Delta® combines the flexibility and response of O-Rings with the wear and friction characteristics of the Turcon® materials in. The double acting performance of the seal follows from the symmetrical cross section which allow the seal to respond to pressure in both directions. Initial contact pressure is provided by radial compression of the O-Ring. When the system pressure is increased the O-Ring transforms this into additional contact pressure, the contact pressure of the seal is thereby automatically adjusted so sealing is ensured under all service conditions.

Turcon® Glyd Ring® T is a double-acting O-Ring energized piston seal for dynamic applications, available in a range of materials (e.g. Turcon® and Zurcon®). Fully interchangeable with the earlier Glyd Ring® T, it provides very good static leak tightness and good resistance to extrusion, also demonstrating excellent friction characteristics with no stick-slip, minimal break-out force and high wear resistance

The double-acting Turcon® AQ Seal® 5 incorporates an elastomer Quad-Ring® and is energized by two O-Rings to improve sealing behavior. It demonstrates excellent results in applications requiring media separation, e.g fluid/fluid or fluid/gas. Works well in higher pressure applications and has a higher sliding speed compared to the AQ Seal®.

A double-acting O-Ring energized seal, the Turcon® AQ Seal® is suitable for sealing between two media such as fluid and gas. It consists of a Turcon® ring and an X-ring or Quad-Ring® inset into the dynamic sealing face. It has excellent sliding properties with no stick-slip effect and can be installed into small spaces.

A single-acting O-Ring energized piston seal for dynamic applications, the Turcon® Stepseal® 2K provides excellent static and dynamic sealing results. This advanced seal is stick-slip free, suits a wide range of application temperatures and demonstrates excellent abrasion and extrusion resistance. Optimum sealing characteristics are achieved by installing in a tandem arrangement.

The Turcon® Variseal® M2S is a single acting seal with scraper lip, based on the design of the Variseal® M2, consisting of a U-shaped seal jacket and a corrosion resistant V-spring. The asymmetric seal profile works well even in media with high viscosity and the Turcon® material and V-spring makes it compatible with a wide variety of fluids and chemicals.
