Vespel CR-6100 pump shaft bearings

Vespel® CR-6100 is an ideal shaft bearing material for multi-stage
LPG pumps.

Vertically Suspended Pump Shaft Bearings

Vespel® CR-6100 Application:

Vespel® CR-6100 is an ideal material for vertically suspended pump shaft bearings, replacing traditional materials like bronze, carbon, or plastic bearings.

What to do:

  • Replace existing bearing materials with Vespel® CR-6100
  • Keep the original design bearing clearance
  • Make sure the pump overhaul results in good rotor concentricity. The rotor should turn freely after assembly.
  • Vertically suspended pumps generally use rigid couplings. There should be a second check after coupling to make sure the rotor still turns freely to avoid coupling-induced shaft misalignment.

Benefits:

  • Greater tolerance of dry-running at start up compared to traditional materials
  • Low wear and long life
  • Durable material that does not break from mechanical or thermal shocks compared to carbon-based materials
