Decision Trees
There are two decision trees in this
section. The first one deals with static
and slow reciprocating applications
where the seals are being squeezed
radially between their ID and OD. Face
seals, which are usually static or slow
rotary, are covered on
Page 4-65. The
second decision tree on
Page 4-39 deals
with radial seals that experience
regular dynamic motion.
The key application considerations
for static & intermittent dynamic rod &
piston FlexiSeals® are gland configuration
and pressure. Pressures above 3000 psi
call for the extended heel option, which
is further explained on
Page 4-44.
The key application considerations
for dynamic reciprocating applications
are pressure, media abrasiveness,
friction requirements, and gland
configuration.
The decision trees in this guide are
to be used as an engineering guide only.
Often several other parameters must be
considered to optimize seal design.
Contact your nearest Zatkoff location
for confirmation of your choice or
further recommendations. Zatkoff also
recommends that any seal be tested in
the application conditions before
releasing for production.
