The latest evolution in sealing: an easy-to-install cartridge with low-friction components combined with a self-lubricating injectable sealing compound. It brings together the advantages of the mechanical seal and the gland packing while removing the drawbacks of both. Forget sudden or catastrophic mechanical seal failures: here there is only gradual leakage, fixed without even stopping the pump.
Easy-to-install cartridge unit with low-friction components, together with a self-lubricating injectable sealing compound. A technology so far removed from the traditional mechanical seal that it can no longer be called by that name alone: it brings together the advantages of mechanical seals and gland packings while eliminating their disadvantages.
HS version of the patented hybrid technology, with the same philosophy: combining the best of the mechanical seal and the gland packing in a single cartridge device.
Version loaded with Style SEVEN graphite fibres, fitted with bronze wear parts and graphite gaskets to withstand up to 450 °C, with peak resistance above 550 °C.
By replacing the wear rings with high-performance lip seals, the 907TD ensures that no leakage can occur. The spring-loaded gland follower allows visual control over the ZLS level, showing when a refill is needed without any actual leakage taking place. Particularly suitable where leakage is not allowed.
