Delta Style 9500 Mechanical Seals Split Seal Application Data Shaft speed: Sizes 1.437" to 2.625" up to 3600 RPM, Sizes 2.750" to 5.250" up to 1800 RPM max. Pressure: Vacuum to 200 PSI Temperature: 250 degrees F Materials Metal Parts: 316SS Springs: Hastelloy "C" Faces: Carbon/Silicon Carbide and Silicon Carbide/Silicon Carbide Elastomers: Viton, EPR, Kalrez, Aflas Features New user friendly, rugged, heavy-duty design accommodates the wides range of applications. Only two major components, assemble and install in three easy steps setting a new stardard for split seal ease of installation. This new design eliminates installation problems commonly associated with current designs! The gland and rotary unit come preassembled; seal installtion takes minutes! The gland has all components, including the stationary seal face, preinstalled. The rotating unit has all components, including: the rotary seal face, and o-rings, preinstalled Balanced, stationary design results in low frictional heat being generated, extending seal life. Precision manufactured design with a miminum number of component parts provide reliable operation and eliminate assembly and installation related problems and failures. Rugged, heavy duty gland castings with ridged bolting surfaces eliminate distortion related failures due to excessive bolt tightening (ex. 2 bolt designs), typically found with "low cost, light duty gland designs." Gland design with concave polished bore provides maximum circumferential flow of liquid, that moves moving solids away from seal faces while keeping them cool. Rotary faces are stabilized under compression utilizing o-rings for their shock and vibration absorption quantities. No glues or adhesives required for installation eliminating time consuming, error prone procedures that contribute to seal leakage on startup. Split seal is mounted outside the box eliminating time consuming, error prone procedures that contribute to seal leakage on startup. Split seal design is ideal for ease of installtion on common end suction ANSI, Non-Ansi paper stock/slurry pumps, vertical turbine pumps or between bearing split case pumps and mixer/agitators. On typical centrifugal pumps, seal design accommodates .002 shaft runout per inch of shaft diameter and .005 axial shaft movement (end play). On low speed equipment, typically mixers and agitators, the seal design accommodates shaft runout of .062 for seal sizes up to 2.625 and runout of .100 for sizes 2.750 - 5.250. Axial shaft movement (end play) up to .015. Special bolting plate adapters or box face adaptors available when unusual bolting or box dimensions are encountered. Choose from spare parts kits for field repairability or optional factory repair program. State of the art, "User Friendly" design technology utilizes the least number of components and costly o-rings, simplifying field repairability, resulting in the "Lowest cost sealing program in industry." Seal design uses only two elastomers (o-rings) minimizing leakage paths. Off the shelf availability in size range from 1.437" through 5.250".
