Enerpac PU-Series electric pumps are compact, low-cost electric hydraulic power units built to drive single-acting tools and cylinders at up to 10,000 PSI (700 bar). The PU-Series trades the larger reservoir and duty cycle of full-size industrial pumps for a smaller footprint and lower entry price, making it a practical fit for intermittent shop and field work. Running an older or discontinued Enerpac power unit? Match the voltage, valve function, and usable oil capacity, then send your specs for a cross-reference.

Item SKU: PUJ1401B

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.

Enerpac PU-Series, Economy Electric Pumps – Frequently Asked Questions

How do I size a PU-Series pump for my cylinder?

Start with the cylinder's oil capacity at full stroke and add a margin so the reservoir is never run dry. Confirm the pump's usable oil volume covers the longest stroke you run, and match the pressure rating to the tool. If you are driving several cylinders, add the volumes together before choosing a unit.

What pressure are Enerpac PU-Series pumps rated to?

Enerpac high-pressure tools and pumps operate at up to 10,000 PSI (700 bar). Confirm the rating on the specific model and on the tool it drives so both sides of the circuit are matched; check the product listing or send us the model number to verify.

Are PU-Series pumps for single-acting or double-acting tools?

The PU-Series is most often configured for single-acting tools with a return-to-tank function, where the cylinder retracts by spring or load. Verify your application before ordering, and confirm the valve function on the specific model listing.

What is the difference between the PU-Series and the ZU-Series?

The PU-Series is the economy tier built for light-duty, intermittent single-acting work at a lower cost and smaller footprint. For higher flow, larger reservoirs, and heavier duty cycles, step up to the Enerpac ZU-Series, Electric Pumps.

What voltage do these pumps require?

Electric models are offered in single-phase and three-phase versions depending on the configuration. Match the pump to your available supply and confirm the circuit can carry the motor draw; check the listing or ask us to confirm the voltage on a given model.

Do I need a separate reservoir or filter?

PU-Series units include an onboard reservoir, but you can add Hydraulic Reservoir Tanks when you need more usable oil. Adding Hydraulic Filters helps keep contamination out of the high-pressure circuit and extends pump life.

Can a PU-Series pump run a hydraulic motor instead of a cylinder?

The PU-Series is built for high-pressure tool and cylinder work, not continuous rotary flow. For rotary loads, pair the right power source with Hydraulic Motors and tell us the speed and torque you need so we can confirm the match.

My PU-Series pump is discontinued — what replaces it?

Give us the original part number along with the voltage, valve function, and the tools it drives, and we will identify a current Enerpac unit that matches the pressure, flow, and reservoir capacity. Send the details to request a quote.
