  • Check Vanes for minimum width.
  • Inspect vanes for improper wear (cupping or uneven wear).
  • Some cupping of the flat surface of the vane is normal. If cupping exceeds 25% of the original thickness, replace the vanes. Make sure to replace the vanes so the beveled edge rides smoothly against the cylinder wall. If the vanes are installed backwards the vane only contacts the cylinder wall at one point.
  • Check and clean the end shield for heat damage or scoring. If any exists, contact your factory representative. Wipe grease off rotor shaft before reinstalling the end shield. Inspect Teflon tube seals in end shield. If the hollow center shows through, replace them.



Vane life depends mostly on two factors: temperature and vacuum level. Run the pump as cool as possible by installing the pumps in an ambient environment that has adequate air flow and a max temperature of 100°F. Also, keep dirt and debris off the pump and motor using compressed air every 2000 hours when performing other maintenance procedures. Starting and stopping should be done as few times per day as possible (no more than twice per day). Run the pump at the lowest acceptable vacuum level.
