SpiralTrac Environmental Controller
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.
An
on-site demonstration is available using our "see-through"
demonstration pump. See how SpiralTrac can move particulates
away from packing or mechanical seals to extend service life
and diminish or eliminate leakage.
SpiralTrac is designed to be used in conjunction
with AW Chesterton sealing devices to solve leakage and maintenance
problems.
