Boulden B-835 is a proprietary blend of carbon-filled PEEK (polyether ether ketone). The unique manufacturing process from Boulden results in a material with a coefficient of thermal expansion very close to the same as carbon steel. B-835 can be used in temperatures from -40 F to 275 F (-40 C to 135 C) primarily in clean services for the following components:

  • Pump wear rings
  • Pump throttle bushings
  • Pump center-stage bushings
  • Pump throat bushings
  • Vertical pump shaft bearings
