Type 613

Wet/Dry Running Single Metal Bellows Cartridge Seal

Using the time-tested and proven dry sliding technology from our Emission Containment Seal (ECS®), the Type 613 is ideal for processes that periodically experience dry running conditions. Applications involving batch processes, tank farms, loading and unloading platforms, and other intermittent processes are perfect for the Type 613 cartridge seal.

Precisely controlled, specially designed bellows and optimal face materials are used in the Type 613 seal. As a result, the Type 613 is able to operate effectively during periods of dry running, and successfully return to sealing liquid when normal running conditions are restored.

An expensive pump and seal overhaul of your conventional wet seals, due to occasional dry running, is no longer required.
