W.F. Taylor Co. Inc. (“Taylor Adhesives”) of Dalton, Georgia manufactures state-of-the- art, environmentally-friendly adhesives for flooring installation. Taylor sells its products throughout the United States and also exports to the Pacific Rim area, Canada, UK and Australia.

When Taylor launched its patented Meta-Tec Wood Flooring Adhesive product in 2003, they bought a used, 411 cubic foot mixer, which had previously been used to mix dry food ingredients. The seals that came on the mixer were MECO''s standardized “MD” seals. The mixer has a 6.5” diameter shaft, turning at 12 rpm. The liquid product is processed at atmospheric pressure and ambient temperature to 90°F.

Plant technician Chuck Dowdy stands beside the blender with The MD seals that came on the blender the MECO seal mounted and purge lines connected. had been working well in the food application, but once Taylor began mixing its adhesive products in the machine, the seals began to leak. The maintenance team replaced the rotating components of the seal, yet it still continued to leak. Plant Manager Alan Wagoner estimated the cost of product loss to be $600.00 per week. An additional cost of operating the MD seals was that they required a nitrogen purge line. Wagoner says that the seals consumed about $336 worth of nitrogen per week.

After about a year, Wagoner’s boss saw a case study in a trade magazine about how MECO’s custom shaft seals had solved a problem similar to theirs. Wagoner contacted the regional MECO distributor, Jerry Chevalier of Mid South Mechanical Sealing. Chevalier came to the plant to take shaft measurements and a pair of custom- engineered seals was delivered several weeks later.
