Double cartridge seal with a “face to face” arrangement which permits operation with barrier fluids (pressurised or not pressurised) and the flushing of the surfaces on the product side. The protected multispring system in the rotating part absorbs the transmission of misalignments, knocks, oscillations and vibrations of the shaft on the contact surfaces and extends the useful life in unfavourable operating conditions. Suitable for applications with highly viscous, sticky, catalytic fluids which have very few lunricant properties or are highly abrasive.
