  • 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

The enhanced hardened bearing system at the heart of GRINDSTONE ESP pumps enhances the reliability and operating range of UNBRIDLED ESP Systems to help achieve your production targets while lowering your operating expenses.
