Used with aluminum packing box

It may be used for low positive pressure and vacuum applications. Using the graphite-impregnated PTFE packing and ACE Stir-Lube, a very-high-film-strength lubricant, pressures down to 7 microns have been obtained at 170 rpm using only a mechanical pump. Speeds over 1000 rpm are not advisable due to the heat generated. Lubrication (4 or 5 drops) is required at intervals depending on the speed of operation (about every two hours at 200 rpm). Packing life is indefinite. Frequent tightening of the packing box is unnecessary once the packing has run in
