Technology

The unique technology has been developed over a number of years to provide total bearing protection by ensuring zero leakage of lubricant to atmosphere and total exclusion of contaminants from the bearing housing. Lip seals are primarily designed to keep lubricants in, and are not always effective at keeping contaminants out. Surveys have shown that even a tiny amount of water or dirt in the lubricant can drastically reduce bearing operating life.

Unique Design

The DMR bearing isolator is based on a simple, unitized, two-piece design normally manufactured in chemically resistant PTFE. The product range consists of a complete family of complementary designs that provides outstanding performance for virtually any application. Applications with pressurized, flooded, or sealed bearing housings can now benefit from Types FS and FN, which feature an internal lip seal, again offering benefits of zero leakage and zero entry of contaminants.

Applications

High-grade PTFE composites in the construction of the standard bearing isolator range ensure a wide range of operating capabilities, including high and low temperature and extreme chemical environments. The use of alternative PTFE fillers extends the physical properties and capabilities into such areas as food production and pharmaceuticals.

DMR bearing isolators can normally replace existing sealing devices, without modification to the equipment. Extending equipment operating life across these industries:

• Chemical Processing

• Pulp and Paper

• Oil and Gas

• Mining

• Food and Beverage
