Seal elements - Import export

Turned parts with mechanical finishing. Ground, hardened, welded, soldered. Pre-assembled with sealing elements and O-rings.

A single-acting sealing element comprised of a U-shaped Turcon® ring and V-shaped metallic energizing finger spring. Suitable for reciprocating and light duty rotary movement. Compatible with most fluids and chemicals and efficient in a wide range of temperatures, it offers low friction with no stick-slip, minimal break out force and high wear resistance.

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.

A single-acting sealing element consisting of a U-shaped Turcon® ring and a metallic V-shaped finger spring. The special flanged heel prevents the seal from rotating/twisting and the short and heavy dynamic lip offers reduced friction, resistance to aging and a good scraping effect even in highly viscous media.

The Turcon® Variseal® HF is a single-acting axial/face sealing element comprised of a U-shaped Turcon® ring and a coiled metallic energizing spring. This design ensures gas-tight sealing even at low temperatures. It is resistant to most liquids and chemicals and has unlimited shelf life.

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.
