Tuthill introduces TuffSeall™ for difficult to seal viscous liquid applications. Customers told us they wanted pumps that don’t leak, and pump seals that can take “whatever we dish out.” Tuthill took them at their word and developed Tuffseall™ to handle a broad range of process conditions. Now available for the GlobalGear internal gear pumps, and HD circumferential piston pumps, Tuffseall™ offers a positive displacement pump sealing solution that delivers the leakage sealing performance of mechanical seals, and simplicity and ease of use of shaft packing. Asphalt Soap, detergents, personal products Printing inks Polymers Lubes and greases Chocolate Will tolerate intermittent run dry Abrasive Solids Corn syrup, molasses, liquid sweeteners Will tolerate moderate amounts of fine abrasive solids Chemical Resistance Same as PTFE for lips. Choice of Viton® EPR or Chemraz® for secondary seals.
