Haskel 420-2 Butane/Propane Extraction Pump

Quantity

Applications

Designed for supercritical extraction of essential botanical oils, like Cannabis

EXT-420-2 Specifications

• Switchable between single and two-stage mode by turning a valve
• Use single stage mode for most of the transfer - when the inlet pressure starts to drop - switch to two-stage mode to pull vacuum as your process requires
• In single stage mode - the pump has identical performance to EXT420
• Two stage mode allows the pump to draw vacuum down to 23-in. Hg

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)
