615 5H15

Stokes 6" series process isolation boosters are designed to be used in conjunction with rotary-piston, dry vacuum, rotary vane and liquid ring pumps to increase pumping speed at working pressures and shorten pump down time significantly.

Features and Benefits

  • Mechanical shaft seal – improved life and serviceability
  • Ringfeder® keyless gear locking system – stronger, faster timing
  • Large shaft diameters – allowing improved performance at high pressures
  • Belt drive or direct drive capability
  • Vertical or horizontal gas flow  
  • Drive end roller bearing – resists belt pull and thermal effects
  • Over-sized anti-friction bearings – increased uptime and longer service intervals
  • Rugged proven design and construction
  • Quiet operation
  • Unique impeller design -Dynamically balanced to minimize vibration
  • High volumetric efficiency
  • High differential pressure – operation capability
  • Available by-pass option for improved pumpdown
  • Available process isolation seal option – optimum protection from dust and particulate contamination
