2 NRODCON he Vulcan ype 95 to 98 eries (referred to below as the ype 9x range) mechanical seals are robust, general purpose, parallel spring, seals, to suit standard metric and imperial housing dimensions, that are commonly found mainly in the marine and textile industries. hese are a direct replacement for ohn Crane /Flexibox ypes R00, R10,R and R series, together with illar 1, 2 and 3 series (CG). ALCAON he ype 9x seal ranges are mainly used in marine pump applications, but are designed to satisfy the sealing requirements of rotating shaft equipment for a wide variety of industrial applications, including; marine, textile, pulp and paper, refrigeration compressors, waste-water treatment etc. ANDARD VLCAN YE ypes 95, 96 and 9 hese are the standard series 9x range, supplied with either solid or inserted rotary face, in a wide variety of face and elastomer materials. All types provide a positive drive to the rotary face, by a heavy duty spring, which is supplied either with left or right-hand wound springs, depending on whether clockwise or anti-clockwise shaft direction. hree versions are available and vary only by the method of providing the drive to the rotary seal face. ype 95 - Drives directly from shaft. ype 96 - Consists of the ype 95 components with the addition of a split ring and washer for simple shaft abutment. ype 9 - Consists of the ype 95 components with the addition of a grub screw drive collar. ype 98 eavy duty, single spring, pusher type seal, supplied with either solid or inserted rotary face, in a wide variety of face and elastomer materials. eal is driven by a grub screw collar, similar to the ype 9. he ype 98 design is unique compared to ype 95, 96 and 9, as it designed to suit different housing sizes and is supplied with a double O -Ring stationary seat, as standard. ANDARD COMONEN YE 95 YE 96 VLCAN DEGN ADVANAGE Face Options All 9x ypes are available from stock, with a wide range of face and stationary materials, including ungsten Carbide, ilicon Carbide, Ceramic inserted rotary faces, Monolithic tainless teel rotary faces, and Carbon, ungsten Carbide or ilicon Carbide stationaries. he full range of stock materials are shown on each seal type page following. Design he Vulcan 9x seal ranges can either be supplied with solid rotary faces or inserted hard faces, with improved tracking capabilities to many competitors equivalents. eal face loading has been designed to ensure optimum seal performance and therefore prolong seal life. ome main competitors seals do not have a linear progression of increasing spring force with shaft size nor optimum face closing forces. uperior Face Combinations As is evidenced from face material factors applied to the V Chart below and from any eal echnical literature. he competitor norms of tainless teel vs Carbon or Ceramic vs Carbon faces, as standard on their seals, have substantially lower capability, performance and life in comparison to Vulcans preferred face combination of Carbon vs ilicon Carbide. his Carbon vs Reaction Bonded ilicon Carbide face combination is offered as the standard by Vulcan, at no extra price, to give the very best quality and performance. Why compromise on quality or accept a higher price for the best seal face combination, for demanding, common marine and textile duties?
