The MECO AH-series seals represent the latest refinement
of MECO’s classic elastomer-driven seal design. While
using the same, patented principle of the MECO EAS,
the AH series is designed to eliminate the process of
setting seal face pressures. For the user who must frequently
sanitize seals, this means simple, trouble-free installation
after cleaning.
AH series seals are for use in low to moderate abrasive
powder processes, on ribbon blenders and paddle mixers,
reactors, screw conveyors, bucket elevators and similar
blending or conveying machinery. AH and AP-series seals
are also used as replacements for lip seals to isolate
lube oil in bearings. These designs can be used in many
cases where installation clearances are too tight to
permit the use of other MECO seal types.
The AH seal uses heavy stainless plate stators, to ensure
flatness and long life, despite extensive handling.
The split AHS seal’s parts can be easily assembled on
the shaft and simply bolted into position. Proper seal
face pressure is established just by snugging the assembly
bolts. There is no calibration process, and correct
face pressures are reliably applied, time and again.
Despite the AH’s "set and forget" design, the seal incorporates
both a basic adjustment mechanism and monitoring provisions
to allow operators to perform preventive maintenance
before product leakage occurs.
AHU unsplit and AHS split seals are particularly well-suited
to food and pharmaceutical applications. They are ideal
for mixers processing dry beverage, spice and flavoring
mixes, where frequent product changes and washdowns
are required. The seals are fitted with flush water
inlet and drain ports, as well as compressed air purge
connection ports. Some, like the seal at right, above, can
be configured for use in explosive environments and
can be certified under the 94-9EC European ATEX Directive.
 AH
seals are custom-designed to fit in unusual space
restrictions on a wide variety of machinery types.
MECO designers work with our clientele to provide
the best fit and most user-friendly design for each
application.
No standard design = No limitations.
The AH series’ "little brothers", the AP series
seals, provide the same predictable performance
and ease of adjustment as the AH series, but in
a smaller package, for installation in even tighter
environments. Both have been built into existing
lip seal housings and can be highly customized to
fit your machinery, such as the multi-shaft compactor at left.
