Epiroc Pit Viper 291 rotary blasthole drill rig
Service technician

Epiroc's solution to virtually eliminate the maintenance visits needed for re-nulling main pumps. The solution consists of an electro-hydraulic displacement control which regulates the differential pressure between ports and reduces the unwanted motion of sub-assemblies.

Reduce maintenance visits, increase productivity

  • Reduced line-of-fire exposure by eliminating the maintenance visits.
  • The technician does not have to manually re-null to limit the pressure difference on the main pumps.
  • Eliminates the unwanted motion of 'downstream hydraulic sub-assemblies', contributing to a safer work site.
