Belland pilotpack Gland packing 3435PILOTPACK 3435 Graphite + PTFE Usage: Pump, shaft - high efficiency Rotate application :: Speed: 25 m / s Temperature range: -100 to 290C Maximum pressure: 25 bar Valve Application: Speed: 2 m / s Temperature range: -100 to 290C Maximum pressure: 350 bar Reciprocal application: Speed: 2 m / s Temperature range: -100 to 290C Maximum pressure: 200 bar Chemical Compatibility: In the range of 0-14 pH is chemically inert. Description: PILOTPACK 3435 Packing is made from superior performance graphite ePTFE yarn, then woven using "Crossplait" manufacturing techniques. This results in packaging that has high thermal conductivity which removes heat from the running surface, which ensures cooler running packaging thereby increasing service life. Yarn has been specially developed using PTFE graphite with high temperature lubricants which are an integral component of the yarn. This process ensures that the lubricant cannot be washed or removed as can occur with several coated threads. Size: all square sections from 3mm (1/8 ″) to 25mm (1 ″) are generally available from stock. Teflon Packing Gland
