The Enerpac HPT-1500 high-pressure, two-speed hydraulic hand pump is for use with hydraulic bolt tensioning tools and hydraulic nuts in construction, manufacturing, and maintenance and repair applications. It should not be used for holding a load or advancing a cylinder. This two-speed hand pump requires fewer handle strokes to move a load than a similarly rated single-speed pump, increasing productivity. When the pump reaches 200 psi of pressure, it switches to the second stage, which requires fewer handle strokes and slows the flow rate to produce more pressure. The pump comes with a gauge and coupler for connecting to Enerpac GT-Series bolt tensioners (sold separately). It can be operated in either the horizontal or vertical position, and it can be used as a vented or a non-vented pump. An internal pressure relief valve helps protect the pump from overload.

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.
