Enerpac hollow plunger hydraulic cylinders are designed for applications that require pulling, pushing, tensioning, testing, or access through the center of the cylinder. The hollow plunger design allows rods, cables, bolts, and other components to pass through the cylinder for specialized industrial work.
This collection includes single-acting and double-acting Enerpac hollow plunger cylinders in both steel and aluminum configurations, giving you options for capacity, weight, stroke, and return method.

Choosing a Hollow Plunger Hydraulic Cylinder
Start with the required capacity and stroke, then determine whether a single-acting or double-acting cylinder is better for the application. Single-acting models use hydraulic pressure to advance the plunger and a spring to return it, while double-acting models use hydraulic pressure for both advance and return.
Choose aluminum when reduced cylinder weight and easier handling are important. For applications that do not require a center hole, browse our General Purpose Hydraulic Cylinders. For high-capacity lifting applications, see our High Tonnage Hydraulic Cylinders.
