Enerpac PMU-10427 Portable Electric Torque Wrench Pump with Heat Exchanger
The Enerpac PMU-10427 two-speed portable electric torque wrench pump is for driving a double-acting hydraulic torque wrench (sold separately) in settings where compressed air is not available in construction, manufacturing, and maintenance and repair applications. It has a glycerin-filled pressure gauge with scale markings in pounds per square inch (psi) and bar. This two-speed pump requires fewer cycles to drive a load than a similarly rated single-speed pump, increasing productivity. An adjustable external pressure relief valve allows accurate torque adjustments and helps protect the pump from overload. A heat exchanger helps prevent freezing of fluid and overheating of oil. The pump has a timeout circuit that stops the motor after 10 minutes of idle time. It has a built-in handle for carrying between locations. The pump has two output ports for connecting to twin torque wrench hoses (sold separately). A pendant switch controls the motor and valves, and the switch has a 10-foot cord to allow the operator to control the pump from a distance. The pump has a 5-foot power cord, and the universal motor can be used with long extension cords or generator-driven power supplies.

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.
