Delta Style 3000 Mechanical Seals Delta Single Cartridge Seal Application Data Shaft speed: To 3600 RPM Pressure: Vacuum to 400 PSI Temperature: See O-ring limitations Materials Metal Parts: 316SS, Alloy 20, Hastelloy "C", Titanium Springs: Hastelloy "C" Faces: Carbon/Sintered Silicon Carbide/Tungsten Carbide in combination Elastomers: Viton, EPR, Kalrez, Aflas, Teflon Features Delta's new global, modular design provides the most advanced, flexible, reliable general service seal available to industry, accomodating 90% of applications encountered worldwide. Rugged, heavy duty gland castings eliminate distortion related failures typically encountered on competitors' "low cost, light duty gland designs." Delta's "Under the Hood" gland design provides clearances 10 times greater than the average clearance provided by other seal manufacturers' designs, which have minimal radial clearance between seal faces and existing stuffing box bores. This feature maximizes the volume of flow around seal faces, resulting in a cooler, cleaner face environment, resulting in extended seal life. This design benefit is maximized on equipment with standard box bores and when converting: packed pumps, component type seals, or older design cartridge seals to the newer "Under the Hood" cartridge seal design technology. Tangential flush connections positioned over the seal faces utilize the largest thru hole diameter available, supplying over 4 times the volume of straight drilled flush holes, providing maximum cooling and cleaning of seal faces maximizing seal life. Interchangeable faces enable application customization, resulting in stable, secure sealing, accommodating the widest range of operating conditions and applications in industry. Choose from: Monolithic, one piece face designs that provide unparalled face stability under fluctuating system operating conditions, resulting in superior emission control capabilities. Two piece face designs that assure optimum seal performance for the most challenging, demanding environments where one piece face construction is vulverable to prematue failure. Rotary inboard faces stabilized under compression are flexibly mounted utilizing o-rings for their shock and vibration absorption qualities. This eliminates premature failures associated with other designs that utilize o-rings on the face I.D.; placing the face in tension, many times resulting in catastrophic failure. Balanced stationary cartridge design utilizes all static o-rings, which eliminates damage to the pump shaft/sleeve or seal normally caused by rotary pusher component or pusher cartridge type seals, allowing use of solid pump shafts which minimize deflection. Positive hold, metal centering clips center the seal in both the axial and radial directions. 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." All seals are pressure tested at the factory assuring 100% sealability during startup.
