Description

The Type 3604/3604HTC/3604HTCDP is a highly reliable dual face-to-face stationary cartridge seal for high-temperature refinery services that is fully API 682 qualified. Dual stationary arrangements are a sealing option within the API 682 specification and have gained popularity with many end users and pump OEMs. These dependable stationary API 682 cartridge seals utilize an impressive design innovation by incorporating high-temperature, corrosion-resistant sealing (HTC) technology for superior seal face stability at elevated temperatures. A DOUBLE-PLY version is available that greatly improves pressure carrying capability to 600 psi(g)/42 bar(g) (consult John Crane Engineering).
