Haskel EXT-420 Butane/Propane Extraction Pump

Quantity

Applications

designed for supercritical extraction of essential botanical oils from plants, like cannabinoids for the cannabis industry.

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)

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)
