Mechaflex R.S.T. P898
Heavy Duty Dual Cartridge Seal
The P898 series is a heavy duty dual cartridge seal intended to provide excellent sealing performance general services, primarily for application for petrochemical and chemical industry. P898 particularly exhibits high performance in the operation of critical process fluids of hydrocarbon, boiler feed water, sour gas, propane and butane, non-flashing hydrocarbon and flashing hydrocarbon.
The improvements in design reliability and robustness are made possible by the utilisation of sophisticated Finite Element Analysis (FEA) Engineering Software. These features are further verified by the usage of ProEight’s high-end testing equipment, the patented mechanical seal static tester – AccuTEST.

R.S.T Series
The R.S.T Mechanical seals are known for its design which were made using ProEight’s in-house FEA programs, SIGMA-FEA and CELC-FEA combined with ANSYS
These software programs analyze combined seal distortion due to pressure, temperature, stress distortion and face loadings. Steady-state and transient conditions coupled with various possible sealing environments gave a clear overview of the mechanical seals’ performance.
