Production times are equivalent to revenue, so maximize your daily extraction capacity with a Corken recovery pump. Recovery up to 2lbs per minute with butane, 4lbs of 70/30 solvent mix, or 6lb of propane with a Corken T-91. These pumps are suggested to be used with a chiller as they have a higher consumption rate of dry ice, hit the contact form and ask us about condensing chillers for your butane and propane extraction. Corken also provides bigger pumps for more recovery, so don't be afraid to ask for something larger. This recovery pump is C1D1 compliant and oil-less.
