Butane & Propane Extraction Pumps

Low-Pressure, High Flow, Oil Free

These units, Butane & Propane Extraction Pumps are designed for subcritical and supercritical Botanical Oil extraction using Butane & Propane. It consists of a large area double acting drive piston directly connected, through a high pressure seal and bearings, to a double acting or 2-stage boost piston. The drive section includes a
spool type directional control valve and poppet type pilot valves to allow automatically reciprocate when compressed air (or a suitable gas) is applied to the drive port. Drive exhaust is routed to a muffler which is positioned near the finned gas section to enhance cooling.

Model: GBX-424 is a double acting configuration. The boost piston provides double acting flow due to the action of the dual inlet and outlet check valves built in.

Model: GBX-412 is a 2-stage configuration. Output is only provided during the “pull” stroke (2nd stage). On the opposite stroke (1st stage), gas is compressed and transferred into the 2nd stage whose volume is somewhat smaller due to the connecting rod.

Model GBX-741 is a double acting configuration. The boost piston provides double acting flow due to the action of the dual inlet and outlet check valves built in.

Model GBX-722 is a 2-stage configuration. Output is only provided during the “pull” stroke (2nd stage). On the opposite stroke (1st stage), gas is compressed and transferred into the 2nd stage whose volume is somewhat smaller due to the connecting rod.
