Gear Joint Kits

WestCoast Rotor has over 30 years’ experience in manufacturing gear joint kits for progressing cavity pumps (PC pumps). Our replacement gear joint kits are available in all OEM-standard sizes. Using advanced CNC production equipment, we are able to ensure perfect precision and repeatability in every part we manufacture. All components are measured and tested for fit and function.

Made in the USA from high quality, domestically-sourced materials, our Progressive Cavity (PC) pump gear joint kits are precision manufactured and machined to meet OEM specifications. Our components meet or exceed the tight tolerances required for reliable, worry-free performance.

Each WestCoast Rotor gear joint kit includes:

  • Ball gear
  • Ring gear
  • Thrust plates
  • Drive keys
  • Seal support ring
  • Set screw
  • Lock nut

All individual components are also available separately.  (Parts vary on select models.)
