The Haskel EXT420 is a pneumatically driven single stage, double acting R600 butane refrigerant transfer pump. EXT-420 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 bypass valves, simply add gauges and hoses to suit your application.

Features and Benefits
- Single stage 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)
- The pump will transfer approximately lb/ min with an inlet pressure of 50 psi (3.4 bar) and an outlet pressure of 150 psi (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)
- 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
