Enerpac ZA-series air hydraulic pumps run on shop compressed air to drive Enerpac high-pressure hydraulic tools, cylinders, and rams without an electrical connection. Enerpac, a Milwaukee-based hydraulics manufacturer founded in 1910, builds air-driven pumps for industrial lifting, bolting, pressing, and tensioning at working pressures up to 10,000 PSI. We supply ZA-series air pumps and cross-reference discontinued Enerpac air-pump part numbers against current-production equivalents — request a cross-reference quote for any model you cannot source.
The right pump depends on the cylinder it has to feed and the air supply you can give it. Match an air hydraulic pump to single-acting Enerpac hydraulic cylinders by oil-volume capacity, or pair it with double-acting rams that need a pump with the matching port configuration. If you are comparing air drive against an electric or hand pump, review the broader Enerpac hydraulic pumps range to weigh duty cycle and power source. For straight load-holding and jacking, confirm fit against Enerpac hydraulic jacks; for the full power-tool side of a setup, see Enerpac hydraulic tools. When the pump feeds a torque wrench or cutter, also confirm the rating of the Enerpac hydraulic hoses and couplers in the circuit.
Air-driven Enerpac pumps stay in service for decades, so the part number on the data plate is often older than the current catalog. We cross-reference legacy Enerpac air-pump model numbers and supply equivalent current-production air pumps that match your pressure rating, oil capacity, and valve function. Pump bodies, seal kits, and air-motor parts on discontinued units can frequently be matched to in-production replacements, and where the original pump is fully obsolete we identify the closest active Enerpac equivalent for the same cylinder. Send the model number, capacity, and the cylinder it drives, and we will return a replacement or equivalent — request a cross-reference quote.
