The Enerpac STF-14H bolting tool pump set includes an Enerpac FSH-14 hydraulic wedge spreader and an Enerpac P-392 hydraulic hand pump and is suitable for spreading a flange joint. The spreader has an Enerpac RC-102 single-acting hydraulic cylinder, delivers 14 tons of spreading force, and holds up to 4.76 cu. in. of hydraulic fluid. Single-acting cylinders use liquid pumped through a single port for rod extension and an internal spring for rod retraction to produce continued movement. The wedge inserts between the flange faces, fits access gaps as narrow as 0.24", and spreads as wide as 3.16". The wedge is stepped for grip and can spread on each step under a full load. The two sides of the wedge move in a parallel fashion to prevent spreader failure or flange damage. The stepped safety block can be inserted into the gap to hold it open. A quick coupler connects the cylinder to the pump. The hand-operated, two-speed pump has a glass-filled nylon reservoir and a nylon-encased aluminum base for corrosion resistance and a fiberglass handle for non-reactivity. The reservoir holds up to 55 cu. in. of hydraulic fluid. 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 pressure relief valve helps prevent overloading. The wedge spreader weighs 15.7 lb. The pump weighs 9 lb. and has a maximum operating pressure of 10,000 psi.

Enerpac manufactures high-pressure tools and equipment for industrial applications. The company, founded in 1910, is headquartered in Menomonee Falls, WI.
