5. Maintenance of the Seals and Process End Disassembly
This section provides the procedure for disassembling the LMC/BMC compressor and its seal
housings for maintenance of the seals. The gearbox assembly is shown
in Reference D, gearbox
module drawing.
Follow your organization’s Lock-out/Tag-out instructions before working on the
compressor. Failure to follow adequate Lockout/Tag-out procedures could cause serious injury.
Follow your organization’s procedures for blocking in or isolating the compressor from the process,
for depressurizing, and for decontamination before disassembly.
Tandem Seal Configurations
Depressurize the seal buffer system before depressurizing the compressor, otherwise reverse
pressure may cause the inboard seal to fail.
Double Seal Configurations
The compressor must be depressurized before the seal buffer system is depressurized, otherwise
reverse pressure may cause the inboard seal to fail.
Item numbers refer to the numbers in
Reference D, gearbox module drawings.
The following procedures apply to all configurations of the Sundyne LMC/BMC compressors. Refer to the
specification sheet to determine the specific configuration and optional equipment included in your unit.
Parenthetical numbers in the text correspond to item numbers in the illustrations and parts lists.
