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.

The tandem configuration of type 116 allows static pressure maintenance in the critical unpressurized range and at low pressure. The security of this function is guaranteed by use of the IDG materials U95, U96 or U99 on the low pressure or atmospheric side.
