  • Enhanced hardened bearing system mitigates the impact of abrasives and limits vibration
    • Provides thrust and radial support throughout the pump to mitigate shaft vibration
    • Limits pump shaft thrust load on the protector. Limits pump shaft thrust load on the protector
    • Improves abrasives handling
  • Mixed-flow design prevents pump plugging and erosive wear
  • Standard and corrosion-resistant metallurgies are available
  • Enhanced bearing system extends the ESP operating range
    • As production declines, GRINDSTONE pumps can handle the corresponding higher pressure and force in the pump
  • Unlike compression pumps, GRINDSTONE pumps are fully assembled in a service center, not at your wellsite
    • Eliminates potential for errors
    • Reduces rig time

Reliable, flexible pumps keep your ESP in the well, where it belongs
