Detailed Description

Features: FR501 is manufactured from du Pont's Kevlar yarn impregnated with PTFE dispersion and treated with lubricant, braided into square cross section. This packing is used in higher pressure applications than are normally tolerated by other types of braided packings. Because of the steel-like strength of this yarn, it can be employed separately or as back-up rings with other types of packing to combine different features into a packing set.This packing has been developed to replace asbestos packing for pump systems. It covers all the service ranges which asbestos packing provides and more. It affords longer life under severe conditions which conventional ashestos packing can not provide satisfactorily, such as sand glurry tin mining, paper slurry,feed water pump of power stations,ect.
