Bronze has been the main material for Bearing Isolator products since it is invented in 1970’. Bronze can offer excellent performance for labyrinth seal, such as no sparking, easy machining and certain anti-corrosion property.

Currently more and more Bearing Isolators are used in various pumps and other special rotary equipment. Some critical environment is forbidden for bronze, such as strong chemical corrosive application. Especially in lithium battery material process industry, bronze and zinc material are extremely prohibited for potential explosive risk.

BRS has launched new carbon fiber filled PTFE material Isolator products after long time test. The new material can offer excellent self-lubricating small formal deformation and low friction properties. It can be used in almost any chemical corrosive environment when matched with PTFE-coated O-ring.

The unique structure can avoid falling apart between the stator and the rotor parts, also the improved structure will ensure the stator will not fall out from the housing during high vibrative condition. Also the low cost of PTFE material will bring huge advantage compared to expensive bronze.We are confident PTFE bearing isolator will help the pump manufacturers to improve their competitiveness in the fiercely manufacturing market.
