Haskel H-420-2 Butane Transfer Pump Pneumatic

EXT-420-2 high-pressure, positive-displacement two-stage piston pumps are safe, proven, reliable, and energy saving butane / propane extraction pumps. The high-pressure pumps offer the flexibility to speed completely variable from zero to maximum lbs/minute. No need for unloaders or bypass valves, simply add gauges and hoses to suit your application. Features and Benefits:

  • Safe for handling propane and butane (Vent port must be connected to an exhaust line that vents leaked gas outdoors)
  • Viton and PTFE seals
  • Stainless steel and aluminum wetted components
  • High butane transfer rates
  • No electrical components
  • Stall against load – start against load – or run dry
  • Requires compressed air to drive the pump – approximately 30 CFM at 100 psi (7 bar) to run the pump at maximum speed (about 60 cycles per minute)
  • Clean – No lubrication required in the gas section – Nothing is added to the gas
