Air Hydraulic Pumps are designed for fast operation, greater versatility and durability. Ideal pump where Shop-Floor air is available at 7 bar. Carrying handles are of treadle design, which allows easy operation by hand and foot. Built in Relief Valve protects hydraulic system components regardless of air pressure. Assembly can be done to fit on larger reservoir (if required). Provides greater speed at low cost. Positive holding even if air pressure turned off. It is recommended to attach a Filter-Lubricator unit at air inlet.
