Models PA91 and PA95 air-over-oil portable hydraulic pumps provide up to 70 cubic inches of flow in the low-pressure stage and 10 cubic inches at 10,000 psi. The pump's pressure-relief valve protects the hydraulic circuit from damage, and the 3-position treadle with a built-in carrying handle provides advance, hold and retract operation.
