Multi-spring balanced double mechanical seal independent from direction of rotation. Double seal shows exellent perfrmance in media that do not have lubricating effect, in toxic, flammable and explosive media.  Sealing fluid system provides seal lubrication, its cooling and prevents precipitation on friction surfaces, thus increasing its efficience and life time. 

Analog to the following types of mechanical seals: Burgmann M74D, Anga VD
