6500 Series

6500 Series end suction centrifugal pumps are based on the proven technology of Gorman-Rupp's Prime Aire and
Prime Aire Plus priming-assisted pump models.  The 6500 Series was designed to extend Gorman-Rupp's end
suction centrifugal pump offering and to better serve applications where a suction lift is not required.  A double volute mitigates shaft breakage and extends the life of the mechanical seals, wear rings and bearings, all while maintaining hydraulic efficiency, while a side access port allows for easy access to pump interior for
inspection and clean out while the pusher bolt capability assists in the removal of the suction flange.  Other features include:

  • Alloy steel shafts with stainless steel options
  • Dual sight gauges for bearing and seal cavities
  • Smart Scroll® indexable discharge location
  • Atmospheric vent
  • Oversized bearings for longer bearing life
  • Double volute on larger models
  • Solids-handing models include side access for inspection and clean out
  • Five-year warranty
