Goliath Vacuum Pump

The GOLIATH Dual Stage extraction pump is a 4:1 ratio pneumatically driven refrigerant / hydrocarbon rated vacuum pump for transferring butane, propane, and similar gases. Because it is pneumatically driven, it is 100% safe and legal to use in a Class 1 Division 1 rated room - unlike most extraction pumps on the market today. Engineered to move large volumes quickly, this pump is ideal for anyone looking to make their essential oil extraction machine operate both quickly and safely. These mammoths boast some of the fastest recovery times on the market with a single pump recovering 1lb of butane in as little as 1 minute*. The Goliath pumps also have the ability to pull near full vacuum. This allows for lower boiling points and faster recovery times without hotter recovery temperatures. Also, this eliminates the need for additional vacuum pumps to evacuate the system prior to flooding. Video: LINK * 1lb/min under ideal conditions.
