  • Variable Speed
  • Oil Lubricated Seals (Can Run Dry)
  • Compact (Will Fit Through a 34″ Opening
  • Wide Range of Performance
  • Can Be Bolted Directly Into a Pipeline
  • Safe Hydraulic Drive Can Be Used Where Electric Power is Hazardous or Impractical
  • Balanced Vane Type Hydraulic Motor
  • Operates With Our HT150DD to HT150DJV Power Units or Other Hydraulic Power Sources with flows of 30-70 GPM
