SpiralTrac Environmental Controller

Is a unique, patented throat bushing specially engineered to transform and control the internal stuffing box environment in rotating process equipment.

SpiralTrac’s success lies in its unique engineered design. By modifying the flows that exist inside rotating processing equipment, SpiralTrac™ allows removal of particulate 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.

​

We offer a wide range of Chesterton pneumatic and hydraulic seals for all of your industrial applications. We stock a selection of their high performance "standard line" wipers, rod seals, piston seals, bearing bands, and rotary seals to address your immediate needs with a quick, efficient delivery time.

Solving your toughest sealing problems with standard or customized Chesterton products that use a combination of unique high performance materials enables you to enjoy significant cost savings with increased performance and reliability.

The Inpro/Seal Bearing Isolator

The Inpro/Seal Company manufactures a Bearing Isolator that provides the highest level of bearing protection available. Inpro/Seal Bearing Isolators are made of high quality bronze and designed to last for at least 100,000 hours compared to the common lip seals which usually fail after only 3,000 hours. With the latest engineering and manufacturing technology, Inpro/Seal can meet your reliability requirements with seals designed specifically for your equipment with quick, timely deliveries.

This two-part dynamic seal consists of a stator press-fitted into the bearing housing and a rotor attached to the shaft. The rotor and stator form a non-contact, compound labyrinth, so there is nothing to wear out.

It protects two ways:

  • Bearing lubricant is captured in the inner portion of the labyrinth and flows back to the bearing housing

  • Outside contamination attempting to enter the bearing housing is captured in the outer labyrinth paths and expelled through a port in the stator by centrifugal force and gravity

Inpro/Seal Bearing Isolators install easily on most shafts, even damaged ones. There's even a split seal for large shafts to simplify installation.
