Enerpac ZU5-Series electric post-tensioning hydraulic pumps deliver high-pressure flow for cable and bar stressing in construction and structural work. Enerpac builds high-pressure hydraulic equipment rated to 10,000 PSI across pumps, cylinders, presses, and tensioning gear, and the ZU electric platform is its workhorse line for repeatable, motor-driven tensioning cycles. If you have an obsolete or superseded ZU part number, we cross-reference it to a current-production equivalent — request a cross-reference quote with your existing model number.
Match the pump to the load it has to drive and the cylinders it has to feed. A post-tensioning pump is only half the system, so confirm the rest of the train before you order. For ram and cylinder pairing, compare bore and stroke against our Enerpac hydraulic cylinders, and review the broader motor- and hand-driven options under Enerpac hydraulic pumps if your duty cycle differs from continuous tensioning. For lifting and jacking duties alongside a tensioning rig, see Enerpac hydraulic jacks. Round out the assembly with the right Enerpac hydraulic hoses rated to system pressure, and check accessory gear under Enerpac hydraulic tools and the wider Enerpac hydraulic tools range. When in doubt on fit, send us your tonnage, plunger count, and the original Enerpac part number and we will confirm the match.
This is where the part number on your old pump tag matters most. Enerpac has revised and superseded electric-pump configurations over the years, and a discontinued ZU number does not mean the application is dead — it means there is a current-production equivalent to identify. We cross-reference legacy Enerpac electric-pump part numbers and supply replacement and equivalent units, and we can map related tensioning-cylinder pairings such as the RCH and RRH hollow-plunger families when the original cylinder is also obsolete. Bring the data plate or the printed part number; the more you give us, the tighter the match. For full Enerpac context across product lines, start at the Enerpac manufacturer page, then request a cross-reference quote and we will return current equivalents.
