R.S.T SERIES

MECHANICAL SEAL



P848

High Temperature Metal Bellows Seal.

The P848 series is a high temperature single/dual metal bellows cartridge seal intended to provide excellent sealing performance general services, primarily on high temperature application for petrochemical and chemical industry. P848 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).
