MECO Shaft Seals, div. Woodex Bearing Company Inc.
MECO EA Series Custom Engineered Shaft Seals
EAU unsplit and EAS split externally-adjustable seals offer complete containment of dry powders, pastes, slurries, fluids, vapors and gases on a wide variety of rotating equipment, where traditional packings fail to seal. EAS seals are manufactured fully-split, permitting installation and rebuilding without bearing or drive removal.
One of the seal’s principal attributes is its ease of operation. The seal face pressures are fully-adjustable; there are no internal springs to loosen due to seal face wear, or to corrode in hostile chemical environments. All adjustment hardware is located outside the seal’s purge cavity, so the seal can be adjusted with no disassembly, often while the equipment continues to operate.
The EAS seal will accommodate significant radial and angular shaft misalignment, as well as thermal growth in high-temperature process machinery.
The EAS’s simple design allows easy disassembly and lends itself particularly well to food and pharmaceutical applications where the seal must be frequently sanitized. Special versions of this seal are available which incorporate sanitary design and manufacturing standards, permitting easy removal, sanitizing, and reassembly.
Installation
In many instances, fully-split EAS seals can be installed in as little as a few hours, once the packing gland, packing and lantern ring have been removed. A variety of mounting adapter plate configurations permits mounting to the existing gland bolts on most equipment with no modification.
Where installation clearances are severely limited, it is occasionally advantageous to move or relocate the shaft sleeve, modify the gland bolt arrangement or remove the stuffing box.
