Haskel Two Stage R600 Butane Extraction Pump 83354-2-87992

The Haskel EXT420-2 is a pneumatically driven two stage, double acting R600 butane extraction pump. 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.

• 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
