As a leading supplier of essential components for industry, Daemar is proud to offer an extensive lineup of shaft seal products. Its wide selection combines the quality and performance that design engineers require, with the total cost of ownership savings that today’s businesses demand. This critical offering includes uniquely designed bearing isolators, which protect bearings by preventing lubricants from leaking and contaminants from entering the bearing housing.
A unique design
The problem with lip seals is that they are primarily designed to keep lubricants in, and are not always effective at keeping contaminants out. Bearing isolator technology has been developed to solve this problem and increase bearing operating life. The isolators provide total bearing protection by ensuring zero leakage of lubricant to atmosphere, as well as the total exclusion of contaminants from the bearing housing.
The DMR Bearing Isolator is based on a simple, unitized, two-piece design, which is normally manufactured in chemically resistant PTFE. The Bearing Isolator ProTech 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 Type FS and FN isolators, which feature an internal lip seal for zero leakage and zero entry of contaminants.
High-grade PTFE composites in the construction of the standard bearing isolator range ensure a wide range of operating capabilities, including the ability to perform in 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 the need to modify the equipment.
In addition to the food and beverage and pharma sectors, these isolators are suitable for use in chemical processing, the pulp and paper industry, the oil and gas sector, and mining.
