How to avoid bearing damage in rotating applications that require the use of aggressive chemicals.
Moisture, dust, and dirt are just a few examples of contaminants that can enter a bearing housing. Contamination causes a number of problems including seal degradation. The result: leakage, which poses a significant safety risk to employees and the environment. Labyrinth seals provide a remedy here. They are low-wear and reliable in use.
But what to do in rotating applications that require the use of aggressive chemicals?
The Garlock non-metallic labyrinth seal ISO-GARD® is ideally suited for these applications due to a special combination of materials. Both the rotor and the stator of the ISO-GARD® are made of glass-filled PTFE. The tortuous labyrinth passage inside the ISO-GARD® prevents foreign matter from entering the housing. Fluoroelastomer o-rings on the rotor and stator, ensure the best compression for optimal sealing. FDA compliant o-rings are also available on request.
Applications for ISO-GARD® include food and beverage industries and also in the paper manufacturing ("black liquor" applications).
The benefits at a glance:
- Filled PTFE construction provides excellent chemical compatibility
- Unitized construction will not come apart during installation
- Meets IEEE 841 Test Standard
- Meets NEMA MG-1
- Available in a broad range of configurations
