2019 Braided Packing/Synthetic Yarn w/ PTFE, Lubricated
(12)CONSTRUCTION
Style 2019 is an interlock braid using carded synthetic yarns thoroughly impregnated with PTFE suspensoid. The finished packing is again coated with PTFE dispersion and a break-in lubricant is added to reduce shaft wear and eliminate glazing at start up.
APPLICATION/SERVICE
Style 2019 is an excellent multi-service packing that finds a wide variety of uses throughout a plant. It handles steam, water, solvents, oils, mild acids and alkalies, and a braod range of other chemicals. It is white in color and will not discolor the flow media. This style is recommended for use in centrifugal, rotary and reciprocating pumps and also mixers, agitators, and expansion joints.

2030 Meta-Aramid w/PTFE and Mineral Oil
(12)CONSTRUCTION
Style 2030 is braided from meta-aramid yarn, each strand impregnated with PTFE-dispersion during the braiding process, lubricated with an inert mineral oil.
APPLICATION/SERVICE
The high mechanical strength of the meta-aramid fiber, combined with the elaborate braiding process, results in a soft and pliable packing wih excellent mechanical and chemical resistance. Because of the low coefficinet of friction, shaft wear is largely avoided, even at high shaft speeds. No excessive heat build-up between the packing rings and the turning shaft; the packing runs cool, remains soft and flexible, resulting in longer servce life. Style 2030 is recommended for all kinds of pumps, mixers, agitators, reactors, etc. for the chemical industry, pulp and paper, sewage plants and more. Suitable for use with a wide variety of media in many different processes, including water, sewage, steam, solvents, chemicals, acids and caustics, as well as general service applications where a mechanically strong packing is required.

2255 Braided Packing/Synthetic Yarn, Graphited, Lubricated
(12)CONSTRUCTION
Style 2255 is an interlock braid using carded synthetic yarns thoroughly impregnated with a special petroleum based lubricant and graphite.
APPLICATION/SERVICE
Style 2255 is a dense, but flexible general service packing that adapts well to worn or scored shafts often found in older equipment. It assures an excellent seal against steam, brine, oil, and mild acids and alkalis. This style is well-suited for applications in rotary and centrifugal pumps and some valves.
