Mechaflex R.S.T. P818
Robust Single Cartridge Seal
The P818 Series is a robust single cartridge seal for slurry application intended to provide an excellent sealing performance for pumps. As one of the members of RST Mechanical Seals, P818 is designed to operate in a wide range of process fluids.
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.
