Enerpac PU-Series, Economy Electric Pumps

How to Choose an Enerpac PU-Series Electric Pump

• Usable oil capacity — Confirm the reservoir holds enough oil to fully stroke your cylinder; an undersized tank will starve the tool on long strokes or multiple actuators.
• Max pressure (PSI) — Enerpac high-pressure tools are rated to 10,000 PSI (700 bar); pair the pump rating to the tool so neither side is the limiting factor.
• Valve function — PU-Series units are commonly configured for single-acting tools with a return-to-tank function; verify whether your application is single-acting or double-acting before ordering.
• Motor voltage and power — Match the supply (single-phase 115V/230V vs. three-phase) and confirm the available circuit can carry the motor draw.
• Coupler and port — Note the outlet port and coupler half so the pump mates to your hose and tool without an adapter.
• Duty cycle — Economy units are intended for intermittent use; for continuous or production work, step up to a heavier series.

Which Enerpac Electric Pump Is Right for the Job?

The PU-Series is the economy tier — pick it for light-duty, intermittent single-acting work where cost and a small footprint matter most. For higher flow, larger reservoirs, and configurable valving on demanding or double-acting applications, step up to the Enerpac ZE-Series, Electric Hydraulic Pumps or the workhorse Enerpac ZU-Series, Electric Pumps. When you need to advance and hold multiple cylinders independently for synchronized lifting, look at the Enerpac SFP-Series, Electric Split Flow Hydraulic Pumps. Where no electric supply is available in the field, the battery-driven Enerpac XC-Series, Cordless Hydraulic Pumps remove the cord entirely.

Complete the System

Build out the power unit with the parts that keep it running clean and connected. Add Hydraulic Reservoir Tanks when you need more usable oil than the onboard tank holds, and protect the pump with Hydraulic Filters to keep contamination out of the high-pressure circuit. For rotary loads instead of cylinders, pair the pump with Hydraulic Motors, and connect tools quickly and leak-free with Hydraulic Quick Couplers matched to the pump outlet.

Cross-Referencing an Obsolete Enerpac PU-Series Pump

If your PU-Series unit is discontinued or hard to source, the equivalent power unit is what gets your tools moving again — not the legacy model number. Give us the original part number, the voltage, the valve function, and the tools it drives, and we will identify a current Enerpac pump that matches the pressure rating, flow, and reservoir capacity you need. As a hydraulics distributor since 1963, we cross-reference older power units against current catalogs so you order the right replacement once. Send the details to request a cross-reference.
