One of Hottest for Aramid Fiber Braided Packing with PTFE Impregnated for Holland Manufacturers

Aramid fiber PTFE packing is braided from high quality Dupont aramid fiber with PTFE impregnated and lubricant additive. This packing can bear higher pressure applications than other types of braided packing. Due to its steel like strength, this yearn can used separately or as back up rings with other types of packing. This packing has been developed to replace asbestos packing for pump systems. It covers all the service ranges which asbestos packing provides and even much better.

Technical Data Sheet

Application Area

It affords longer service life under severe conditions which conventional asbestos packing can bot provide satisfaction, such as mine, tin ore, paper pulp, feed water pump of power stations, etc.

When you spend your life in the water, I guess you tend to develop a good intuition for its subtleties. Dolphins have been observed to create bubble rings by exhaling air carefully in the middle of the vortices caused by the motion of their fins through the water, among other techniques.

Besides being nice to look at (and a neat demonstration of fluid mechanics), this phenomenon also might throw some light on dolphin cognition, since the skill to create the rings is a bit subtle and tends to be taught from one dolphin to the next via careful observation and practice. I’m also intrigued by the report that they seem to be using sonar to locate the vortex in the water, since that would be a fairly amazing bit of audio analysis.
