| Pumped Media Seals |
|
The optimum primary seal can be chosen to match the pumped media
and duty conditions. Single or double mechanical seals include flushed
or aseptic variants. For arduous duties hard faced seal materials such as
tungsten carbide or silicon carbide can be used. A wide variety of commercially
available mechanical seal options including single and double
cartridge seals are available for sludge and other difficult applications.
Packed glands offer a simple, low cost, and easy to maintain controlled
leakage sealing arrangement.
Pumped media wetted elastomers are EPDM, NBR, FPM all FDA
conforming or PTFE for chemical applications.
