Maximum Safety for Demanding Sealing Applications
The double cartridge seal is a pre-configured mechanical seal with a dual sealing system, specifically designed for critical applications that require the highest levels of safety, reliability, and leakage control. It consists of two seal faces arranged in series – a primary and a secondary seal – providing maximum sealing performance for aggressive, toxic, or abrasive media.
Thanks to its pre-assembled cartridge design, the double cartridge seal can be installed quickly and accurately without complex adjustments or special tools. It is ideal for use in the chemical, pharmaceutical, food processing, and water treatment industries – especially where product and environmental protection are top priorities.
With the option for barrier fluid and pressure monitoring, the double cartridge seal ensures controlled operation, early leakage detection, and extended seal face service life.
