Description
Parker developed the unique ProTech design to provide
unmatched two-way sealing for zero lubricant leakage and
total exclusion of contaminants. This is accomplished by
using non-contact labyrinth seal technology. ProTech features
the most effective labyrinth design for both dirt exclusion and
oil retention and is far superior to isolators that rely on
internal O-rings or other internal seals for sealability. If you
want more than just an O-ring for bearing protection — step
up to ProTech!
Applications
Chemical Resistance
Advanced proprietary PTFE compounds mean
ProTech is well suited for caustic environments
such as citric acids found in juice processing and
strong sulfides in pulp and paper processing.
ProTech’s superior chemical resistance allows for
the standardization of a single material within a
plant, eliminating the need to stock duplicate sizes
in expensive stainless steel, Hastelloy® or other
exotic materials. PTFE is compatible with over 160
chemicals vs. 11 for bronze and 30 for stainless
steel.
Food Processing
ProTech’s unique
designs and superior
performance are “eating the
competition’s lunch” in the
food processing market. The
WD is an economical profile
for high volume, disposable
equipment such as wash
down grade motors and
drives. It also greatly
reduces maintenance costs
and downtime in food processing applications
such as picker hubs in poultry processing. Anti-
microbial and FDA materials are readily available.
Pumps, Motors and Gearbox
The isolator
protection you rely on
for protecting bearings
in pumps and motors is
also available for
gearbox applications.
ProTech 360 is a hybrid
design that incorporates an outboard labyrinth for
contaminant exclusion and PTFE lip technology for
positive oil retention, even in vertical down
applications. ProTech 360 is used by numerous
OEMs for their most demanding gearbox
applications.
