A dual pneumo-hydraulic pump unit is provided. The dual pneumo-hydraulic pump unit includes a central pneumatic cylinder that works in the center of two hydraulic piston pumps. The two hydraulic piston pumps are mounted parallel to the plunger of the central pneumatic cylinder, positioned one on each side. Compressed air or other pressurized gases are used to move the central pneumatic cylinder, as a source of motor energy to pump oil under pressure to a hydraulic pressure accumulator for later activation of hydraulic actuators.
