MECO’s EA Type 1 seal is available for a variety of applications in pulp and paper mills – particularly stock chest agitators, repulpers and chip screws – and in other processes involving wet, abrasive slurries like drywall mud. The EA Type-1 accommodates severe shaft runout and lends itself well to applications where mechanical packings and traditional mechanical seals fail to function. The seals are manufactured fully split, in most cases permitting installation and rebuilding without removal or modification of the existing stuffing box, bearing, or drive.
When Are EA Type-1 Seals The Best Option?
EA Type-1 seals are effective on horizontal stock chest agitators – on cantilevered shafts and on older through shafts and mid-feather agitator designs. MECO seals were originally developed for screw conveyors, and they still excel on stock washer repulper screws and on TMP chip conveyors. Bottom-entry and side-entry pulpers are best sealed with MECO’s EP Type-1 seal.
