The Enerpac SCR-256H single-acting cylinder pump set includes the P-392 lightweight two-speed hydraulic hand pump and a RC-256 twenty-five-ton capacity general purpose hydraulic cylinder for lifting, bolting, or applying pressure in intermittent and non-repetitive construction, manufacturing, and maintenance and repair applications. The P-392 hand pump has an internal pressure relief valve that protects against overload. The nylon-covered aluminum base, glass-filled nylon reservoir, and fiberglass handle provide corrosion resistance and are lighter than steel hydraulic hand pumps. The two-speed pump requires fewer handle strokes to move a load than a similarly rated single-speed pump, increasing productivity. The pump handle locks into place for secure transport. The set also includes a 6’ safety hose, a 25.5-ton hydraulic force and pressure gauge, and 1/2" gauge adaptor to connect to the pump’s 3/8" National Pipe Taper (NPT) threads port.

Hydraulic pumps lift, bolt, or apply pressure to objects by pressurizing and moving hydraulic fluid. A hydraulic pump consists of a base, a reservoir that holds hydraulic fluid, and an operating mechanism, such as a handle or foot pedal, an electric motor, compressed air, or a gasoline engine. When the operating mechanism is activated, pressurized hydraulic fluid from the reservoir is delivered through an attached hose to a hydraulic cylinder. The pressurized hydraulic fluid in the cylinder lifts the cylinder’s piston, which in turn lifts the load. Hydraulic hand pumps are usually made of steel, or aluminum and nylon, and can be single-speed or two-speed. They are used in a wide range of applications, such as construction, manufacturing, and maintenance and repair applications in both industrial and home settings.

Enerpac manufactures industrial hydraulic equipment for lifting, workholding, and other applications, and provides integrated lifting solutions for bridge construction, mining, shipbuilding, and other industries. The company, founded in 1959, is headquartered in Menominee Falls, WI.
