SpiralTrac™
The SpiralTrac™ Environmental Controller is a unique, patented throat
bushing specially engineered to transform and control the internal
stuffing box environment in rotating process equipment. With unique
versions designed to work with both mechanical seals and packing,
SpiralTrac™ has set the standard in industrial process applications
worldwide for increasing equipment reliability, decreasing housekeeping
cost and reducing flush requirements.
SpiralTrac’s success lies in its unique engineered
design – by modifying the flows that exist inside rotating processing
equipment, SpiralTrac allows particulate to be removed from the stuffing
box (and away from packing or mechanical seals), permits air to evacuate
the stuffing box on flooding, and minimized heat buildup in the stuffing
box by creating circulation around seal faces.

Used
with packing to reduce flush, leakage, wear, and maintenance costs.

Used
with packing to reduce flush, leakage, wear, and maintenance costs.
Only the insert element itself (not the
holder) requires occasional replacement. Thereby reducing future
re-order costs. |

Version N
(Small or no flush, non-fibrous applications)
Used
with a small flush or no flush in Non-fibrous applications. Should
be the version specified for seals whenever non-fibrous contaminants
are handled and the equipment will be disassembled for installation.
In Pulp
& Paper - acids, caustics, liquors, etc.- normally in 316SS.
In
Mining – slurries, chemicals, water intakes, etc.

Version F
(Flush only, split)
Used
only with flush typically 5-8 gph (0.3 - 0.5 lpm). Version F
is ideal for use with split mechanical seals. Since split devices
are intended for installation with the pump in place, however, the
pump cannot be modified to incorporate the air vent or exit groove
extension required for flush free operation.

 |
Version D
(Small or no flush, fibrous applications)
Used in
fibrous (paper stock) applications with a small flush, 5-8 gph
(0.3-0.5 lpm), if the product is aerated and single seals are used,
or with no flush. (If uncertain, start the pump with the flush and
decrease slowly. If the gland heats up the stock is aerated, turn
the flush back on.)
Available in 316/416SS, ESC (Carbon-graphite, ceramic-filled PTFE)

Version C
(Small or no flush, chemical applications)
Similar
to the version N, but with an integral bottom drain that allows
process to drain from the seal cavity on pump shutdown, minimizing
process crystallization problems on pump restart and increasing
maintenance safety.
|
 |
An easy
to install adaptor for mechanical seal applications. Installs easily
between the seal and seal cavity. |
