BV-2 Balanced mechanical seals
DIN 24960
The mechanical seal design of BV-2 type prevents the springs from contacting the delivery fluid and due to this problems which occur with other multi-spring seals are avoided. The profiled sealing surface of the rotating part provides for good hydraulic relief, making it possible to use the BV-2 type mechanical seal at a pressure of up to 40 bars.
Different types of sealing materials can be easily used due to the simple replacement process and commonality of the sealing surface.
The replacement of all seal components is easy and requires minimal cost, which makes seal repair an easy and inexpensive procedure.
