Product Description

This Palmetto style 1555 graphite filament compression packing with a graphite coating and a solid lubricant protects rotating and reciprocating shafts, valves, and agitators from fluid leaks in severe service and high-speed applications. The interwoven braided packing seal is made of a 99-percent assay graphite filament impregnated with fine graphite particles. Graphite resists high temperatures and pressures, exhibits a low coefficient of friction, and transfers heat away from the shaft to prevent glazing and scoring, reducing leakage and extending the packing and sleeve life. The graphite coating further reduces frictional heat to allow for higher shaft speeds and higher temperatures. The packing seal contains a solid lubricant that provides a bearing film between the shaft and seal to prevent any wicking or fraying. This packing seal is compatible with media in the pH range of 1-14, except for strong oxidizers in the 1-2 pH range, such as oleum, fluorine, and fuming nitric acid. It has a maximum pressure limit of 3,500 pounds per square inch (psi), a pressure-velocity (PV) factor of 800,000, and a shaft speed of 4,000 feet per minute (fpm). It operates to a maximum temperature of 1,200 degrees F (650 degrees C) in steam, 800 degrees F (427 degrees C) in oxidizing atmospheres, and 6,000 degrees F (3,300 degrees C) in non-oxidizing atmospheres. Style 1555 is suitable for use in rotating and reciprocating equipment such as digesters, boiler feed pumps, and chemical pumps.Specifications
