Type “E” Water-Cooled
Balanced Double Seal
The Type “E” seal consists of two carbon seals inside a stuffing
box that is attached to the backplate. Its sealing action is the
same as the external balanced seal. This seal design is used in
applications where a vacuum-tight, cool operating seal is
required.
NOTE: The
C-100 is not available with
“DG”, “E” or “F” seals.
Periodically inspect all parts of the pump to prevent malfunctions
caused by worn or broken parts.
