AROLAN MERKEL AROLAN 6210
  

AROLAN 6210 is a multi-filament aramid yarn with PTFE impregnation and lubricant that has already been used successfully in a wide range of applications. It offers a high level of resistance to wear, particularly where hard crystalline or abrasive media have a destructive effect on the packing. Proven areas of application include media containing solid particles, refiners, juice pumps, slurry pumps, as well as plunger pumps, dryers and mixers. PTFE is bonded to the smooth surface of the yarn in a special pre-treatment process; it optimizes running characteristics, closes leakage paths in the braid and improves adhesion between yarns. A physiologically neutral running-in lubricant assists sealing effect even at low levels of gland pressure.

The PTFE yarn filled with graphite shows very good running qualities and protects the surface of plungers sand shafts. The aramid yarn braided into the corners stabilizes the packing and hinders gap extrusion, thus ensuring long service life. It's particularly suitable for difficult sealing situations such as bridging large sealing gaps and sealing against abrasive media. In high-pressure plunger pumps long operating cycles have been achieved with constant sealing effect through the use of end rings in a precompressed spring packing set. These sealing sets can be supplied as a complete unit ready for installation.

  • Pressure (PSI): 7150
  • Max. Temp (F°): 536
  • Speed (ft/s): 6.4

AROCHEM MERKEL AROCHEM 6212

It has been successfully used in the sealing of mixers, kneaders and soot blowers. The use of end-rings usually required where PTFE silk packings are applied against high pressures and borderline temperatures is not necessary. This yellow/white packing can be used in an extensive range of applications due to the chemical resistance provided by PTFE silk and aramid yarn.

  • Pressure (PSI): 7150
  • Max. Temp (F°): 536
  • Speed (ft/s): 6.4
