BOT ring pair
The pressure balanced ring pair
- BOT ring pair (balanced overlapping tangent)
- even pressure distribution over the whole packing
- increased lifetime of the ring pairs
- considerably power friction at the piston rod
- thoroughly tested under extreme conditions
- proven HY-material selection to provide optimum life
Conventional ring design
BOT ring design
A unique ring design to overcome an old problem
The new design provides an even pressure distribution through the packing. Each single BOT Ring Pair (Balanced Overlapping Tangent) is an engineered combination of radial/tangential cut rings, whereby the radial cut ring supports the tangential cut one. This means remarkably increased lifetime of the BOT Ring Pairs and consequently of the whole pressure packing.
