“…Metal bellows seals offer benefit of having only the stable secondary seals. This allows their application in hightemperature services where suitable O-ring elastomers are not available [1]. Metal bellows seals are also a costeffective alternative for services where chemical resistance or cost of O-ring materials is an issue.…”

A mechanical seal is a device that used to reduce leakage containing pressure or ignoring contamination. Mechanical seal is the device used in centrifugal Pumps, Mixers, Agitators and Compressors to arrest or reduce the leakage. The mechanical seal standard API 682 provides the design guidelines for the seals which are fits below 110mm shaft diameter and 4.2 N/mm2 seal chamber pressure. Any seal more than these parameters required special engineering or guidelines needs from technical service. The main aim is to design the mechanical seal for more than 110mm shaft diameter and more than 4.2 N/mm2 pressure. Since the basic seal components are mostly standardized and already tested than the seal gland connections are seems to be critical for large shaft diameter and high or heavy pressure applications. Hence the stress and deflection of the mechanical seal gland is analyzed based on barrier pressure and seal chamber pressure with the help of Inventor and another critical area is the seal drive arrangements.

“…Mechanical seals are the sealing device for any rotating equipment, which prevents the leakages of liquids, gases or any other hazardous process fluids through the clearance between the housing case and the rotating shaft of the pump [1][2][3]. It is specially designed to be used in centrifugal pumps, mixers, compressors, boiler-feed pumps, agitators and rotary unions.…”

The present work investigates the friction characteristics of high carbon high chromium steel (HCHCr) stationary seal in contact with resin impregnated carbon rotating seal without any interfacial lubricant. An experimental setup was designed and fabricated to study the frictional characteristics of the seal for varying normal load and at a constant speed. The reliability and frictional performance had been improved further by providing DLC (diamond like carbon) and WC/C (tungsten carbide/carbon) coating over the substrate HCHCr D2 steel surface. Compared with the conventional stainless steel (316 SS) mechanical seals, uncoated HCHCr D2 steel had shown better frictional characteristics. Also further deposition of DLC and WC/C film on HCHCr D2 steel had shown significant improvement in the frictional torque, frictional coefficient and face temperature rise. The high hardness and low surface roughness of DLC and WC/C coated seal resulted in low and stable friction coefficient in the range of 0.04-0.05 without any measurable wear.

“…Mechanical seal is a device that helps in joining systems or mechanism together preventing leakage, containing pressure, and excluding contamination [7,8]. The industrial applications of mechanical seal were innumerable such as for pumps, mixers, dryers and other specific equipment, commonly used anywhere, in which liquid and gases were transferred by rotating equipment [9].…”
