Enerpac SCH-121H Single Acting Cylinder Pump Set RCH-121 Cylinder with P-142 Hand Pump

• High-pressure, lightweight hydraulic hand pump with a hydraulic cylinder for lifting, bolting, or applying pressure.
• Includes a single-acting, 12-ton capacity, hollow plunger cylinder for pushing and pulling applications.
• Internal pressure valve protects against overloading the pump.
• Two-speed operation requires fewer handle strokes than single-speed hydraulic hand pumps.
• First-stage pressure rating of 200 psi and second-stage pressure rating of 10,000 psi.

The Enerpac SCH-121H single-acting cylinder pump set includes the P-142 high-pressure, lightweight two-speed hydraulic hand pump and a RCH-121 twelve-ton capacity hollow plunger hydraulic cylinder for pushing and pulling in intermittent and non-repetitive construction, manufacturing, and maintenance and repair applications. The P-142 two-speed hand pump requires fewer handle strokes to move a load than a similarly rated single-speed pump, increasing productivity. An internal pressure valve helps protect the pump from overload. The glass-filled nylon reservoir, nylon-covered aluminum base, and fiberglass handle provide corrosion resistance and are lighter than steel hydraulic hand pumps. The pump handle locks into place for secure transport. The set also includes a 6’ safety hose, a 10-ton hydraulic force and pressure gauge, and 1/2" gauge adaptor to connect to the pump’s 1/4" 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 oline 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.
