New high abrasion resistance materials extend service life for seals range
29 January 2007
Sealing technology specialist, Garlock, has introduced a new sealing material for its KLOZURE range of high performance dynamic seals. KLOZURE MILL-RIGHT is a specially engineered elastomer, available in three grades, which has been shown to offer up to 90% increased abrasion resistance over conventional lip seal material. As any dynamic lip seal is subject to wear the reduced abrasive properties of MILL-RIGHT assures reduced mean time between repair (MTBR) and longer bearing life. The low coefficient of friction offered by the material means less heat generated and lower power consumption with a resultant higher equipment efficiency.
Colour coded for easy identification, MILL-RIGHT N, replacing conventional nitrile material, is black and is suitable for continuous temperatures of 200ºF and peaks of 250ºF. MILL-RIGHT ES, replacing Hydrogenated Nitrile material, is blue and is suitable for continuous temperatures of 300ºF and peaks of 350ºF. MILL-RIGHT V, replacing Fluoroelastomer material, is green and is suitable for continuous temperatures of 400ºF and peaks of 450ºF.
Garlock conducted Taber Abrasion Resistance Tests (to ASTM D4060) comparing the MILL-RIGHT materials against its own ‘conventional’ materials – nitrile, hydrogenated nitrile and fluoroelastomers. Abrasion reductions improved by 73% using MILL-RIGHT N and increased to 90% using MILL-RIGHT V.
