A p p l i c a t i o n s
Rugged mechanical seals are available
in a wide variety of elastomers for
handling practically every industrial fluid.
All components are held together by a
snap ring in a unitized construction
design.
General industrial applications including
chemical processing, food and
beverage, petrochemical processing,
pharmaceutical, wastewater and power
generation.
Mechanical drive design reduces
slippage on shaft and sleeve to
eliminate galling and premature wear.
Lapping process results in high
precision finish with optimal flatness.
Compact design permits use in all
types of rotating equipment--centrifugal
pumps, mixers and agitators.
Seals can be repaired easily on-site or
at any John Crane Seal Repair Center,
and/or converted to wedge-type seals
for broader service capabilities.
