The 15GBM is a gas powered pump that produces 10,000 PSI of hydraulic pressure. It is designed to handle any high-pressure tool up to and including the 60 ton press. The two-stage pumping system allows for rapid ram advance. The “suc-o-matic” valve helps tools retract faster. The manual control has three settings: advance, hold and retract. Whether making one crimp or 1,000 crimps, the 15GBM is the lightweight, portable answer.
