New Inpro/Seal mini66 Bearing Isolator Provides Permanent Bearing Protection in Applications with Limited Space

Two European hydropower plant operators have replaced the bearings on their Francis-type turbines with water-lubricated bearings from Canada’s Thordon Bearings after oil was leaking from their original metal bearings.

Matching the right elastomer to an application is key to ensuring an o-ring’s optimal performance and mitigating premature failure. One critical factor to consider is resistance to process fluids.

Sustainable ingredients will help curb the carbon footprint of some polymer compounds at Freudenberg

Sulzer has launched a new shut-off device SOD for horizontal SALOMIX™ SSA agitators that significantly reduces the time spent on servicing the seal. The device enables seal maintenance without emptying the tank, which makes the feature especially useful for very large tanks, wastewater treatment plants, and other critical processes.

In appliances used for water purification and carbonated water, the valve of a carbon dioxide cartridge and the pressure-reducing valve on the device itself must be joined with a secure seal. Now, Freudenberg Sealing Technologies has developed a patented, high-performance polyurethane seal for a customer that has a specific geometry that not only accommodates different valve dimensions on the various gas cartridges, but also offers high impermeability under long-lasting pressure.

Thordon Bearings has further strengthened its presence in the Taiwanese market, delivering water-lubricated elastomeric polymer bearings for installation to cooling water pumps commissioned for a major power plant expansion project.
