The Enerpac P-392AL aluminum two-speed hand pump is portable, has a main handle and a second handle for two-hand use, holds up to 55 cu. in. of hydraulic fluid, and is suitable for powering hydraulic equipment. The pump has an aluminum reservoir and a nylon-encased aluminum base for corrosion resistance and a fiberglass handle for non-reactivity. Two-speed pumps typically require fewer handle strokes than single-speed pumps for efficiency and optimal flow. The handle displaces 0.687 cu. in. of fluid per stroke at 200 psi (pounds per square inch) or 0.151 cu. in. per stroke at 10,000 psi. The handle locks for carrying. An internal relief valve helps prevent overloading. This hydraulic pump has a maximum operating pressure of 10,000 psi.
