EXT-420 Butane Propane Extraction Pump 

High- Pressure Positive Displacement Piston Pump-

Single Stage Pneumatic Recovery Pump 

EXT-420 high-pressure, positive-displacement single 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.

Applications

  • Designed for supercritical extraction of essential botanical oils
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

Operation

Proper operation of the Haskel EXT420 pumps will require the following additional equipment:

  • Compressed air source capable of providing approximately 25 CFM of air at 90 psi (6.2 bar) or higher (Compressor must be located in an area away from the LPG gasses)
  • Compressed air filter filtering to 40 microns or better
  • Drive air pressure regulator
  • Drive air speed control valve - such as a gate valve or a globe valve (not a ball valve)

EXT-420 Specifications

  • Single stage
  • Ideal when inlet pressures are 25 to 50 psi (1.7 to 3.4 bar) and outlet pressures are 125 to 150 psi (8.6 to 10.3 bar)
  • Pump will transfer approximately ½ lb/min with an inlet pressure of 50 psi (3.4 bar) and an outlet pressure of 150 psl (10.3 bar) at maximum speed
  • Will draw pressure down to 15 psi (1 bar) with an outlet pressure of 150 psi (10.3 bar)
