R.S.T SERIES

MECHANICAL SEAL



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 utilization 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 and mechanical seal dynamic tester – AccuDYN (Patent Pending).
