Special Configurations
AccuSeal energizing devices can be
customized to meet most special
application requirements.
Silicone-Filled Spring Cavity
Silicone-filled seals for sanitary (i.e.
food grade) applications conform to
FDA requirements for inert contact with
edible medias. Silicone gel fills the
spring cavity, preventing entrapment of
biological contaminants in the seal. This
design also works well with
semi-viscous, slurries or adhesives by
keeping grit from packing into the
spring cavity and interfering with the
proper operation of the spring.
Coated Springs
In applications where the media cannot
come in contact with any metallic
substance, AccuSeal can also offer
Teflon®1 coated springs.
Nested Springs
When additional spring load is required,
AccuSeal can offer nested springs,
which increase the amount of spring
force over a larger axial surface area.
By nesting one or more springs inside
of each other, the load bearing area can
be increased to accommodate a larger
sealing area and greater initial spring
load.
Tandem Springs
By placing two springs “side-by-side” in
tandem, an AccuSeal can be used to
span a larger radial gap without
sacrificing seal performance. This
spring design provides twice the
deflection range to accommodate wider
gland tolerances and greater amounts
of dynamic play.
O-ring Energizers
Elastomeric o-rings can be used to
energize an AccuSeal design in special
applications where metal energizers
are not acceptable. However, these are
not recommended due to temperature
and media compatibility limitations.
