In BV-2 seal design springs are not emerged in operating fluid. In that manner spring blocking and material incompatibility problems are eliminated. In BV-2 seal design rotating part O-ring is in static state all the time, even during operation. Seal face wear is compensated by springs, therefore O-ring is never under dynamical load. Mechanical seal type BV-2 can be applied in conditions of pressure up to 40 bar due to shaped seal face cross-section. Standardized seal face dimensions allowe simple application of wide range of seal face materials and easy component replacement.
