Do You Need an Enerpac 50-Ton Press, a Double-Acting Pump, or Neither?

Start With the Job, Not the Catalog

I've managed purchasing for a 240-person industrial services company since 2020. My role sits between the maintenance crew and finance, so I get asked 'Can we order an Enerpac?' a lot more often than 'Should we order an Enerpac?' The second question is the one worth answering first.

There is no single Enerpac setup that fits everyone. A 50-ton press is brilliant in one shop and wasted floor space in another. A double-acting hydraulic pump is a no-brainer for some crews and an unnecessary cost for others. It comes down to three scenarios: pressing, pushing and pulling with hydraulics in the field, or cutting.

The rest of this guide walks through each one, including a mistake I almost made when our maintenance team asked for more pressing capacity.

Scenario A: You Need to Press Bearings, Bend Steel, or Straighten Parts

If you've been searching for an 'enerpac hydraulic press 50 ton', this is probably your scenario. You want a fixed press frame, a hydraulic cylinder, and a bed that can handle regular heavy jobs in one location. The key decisions aren't about brand loyalty. They're about tonnage, working space, and the pump that drives the press.

Tonnage gets the most attention, and it's where I see buyers get trapped. In 2023, we almost ordered a 50-ton press because one seized component had pushed our old 20-ton unit to its limit. When I reviewed the maintenance logs, that job was the exception, not the rule. Most pressing work fell below the bigger machine's capacity. My gut said to buy the larger press so we'd never be stuck again. The data said we'd be paying for capability we would rarely use, and that a larger cylinder can be slower when matched with the same pump.

What to check before ordering:

  • Real tonnage range. Focus on the largest regular job, not the one-off crisis. If regular work is around 35 tons, a 50-ton press leaves a reasonable margin. If it's under 25 tons, a smaller press may serve you better and avoid the expense of unused capacity.
  • Working area. Bed width, throat depth, and maximum opening height matter more than the tonnage number. You can't fit a tall assembly into a frame with too little clearance.
  • Pump speed. Manual pumps suit occasional use. For repeated pressing, a powered pump keeps the crew moving; otherwise the press can end up sitting unused.
  • Cylinder return. Many press setups use single-acting cylinders that return by spring or gravity. That's usually fine for a downstroke press and doesn't require a double-acting pump.

Looking back, I should have asked for a utilization log before we bought our last press. At the time, I was trying to make one supervisor happy and almost sized the machine around a rare event. The lesson stuck with me: a 50-ton press is a specific tool, not a status symbol.

Scenario B: You Need Hydraulic Power Away From the Bench

This scenario is for teams that don't spend the whole day next to a workbench. They're pulling flanges apart, lifting equipment in the field, or positioning heavy components on a job site. What they need isn't a press frame; it's a hydraulic pump connected to cylinders or hydraulic tools.

What is a double acting hydraulic pump?

A double acting hydraulic pump is a pump-and-valve package with two pressure work ports instead of one. In a typical single-acting setup, the pump sends oil to the cylinder to extend it, and the return stroke is handled by a spring or gravity. In a double-acting setup, the control valve shifts oil to the other port so the cylinder retracts under power.

Put another way: single-acting is push; double-acting is push and pull. You get powered movement in both directions.

When is that worth the extra cost? If a job requires pulling toward the cylinder, holding a position against an external force, or cycling back and forth many times, a double-acting pump is the right call. It also helps with long hoses, since the return stroke has real hydraulic force behind it instead of relying on a spring.

One warning: don't order a double-acting pump unless the cylinder is double-acting too. The pump can't create two-way movement if the cylinder has only one hydraulic port. It sounds obvious, but mismatches happen when people order from a spec sheet instead of checking the existing equipment.

The bigger trend I've noticed since 2020 is how practical battery-powered pumps have become. Our field crews used to avoid hydraulic tools when there was no compressed air or power outlet nearby. In 2024, we added Enerpac battery pumps for remote work, and it changed how often the tools actually got used. The fundamentals of hydraulics haven't changed; the execution has.

Scenario C: You're Cutting, Not Shaping

The third scenario is easy to overlook. Sometimes the job isn't forming metal into a new shape; it's removing rusted bolts, cutting chain, or slicing through rebar. If that's the daily reality, the right purchase is probably a cutter rather than a press or pump.

For occasional cutting, a good manual bolt cutter with sharp, hardened blades is simple and reliable. For repeated cuts or hard-to-reach spots, hydraulic cutters take most of the effort out. Either way, the blades are the wear items. Bolt cutter blades can chip, dull, and need replacement long before the tool body gives out.

I'm honestly not sure why so many buyers expect blades to be universal across brands and models. My best guess is that the word 'blade' sounds generic. It isn't. The cutting head, blade dimensions, and pin spacing vary, so replacement blades need to match the specific cutter you own.

And if you ended up here because you were searching for a chainsaw bar size chart, I'll be straight with you: this isn't that chart, and a chart alone probably won't solve your problem. Guide bar length is only part of the specification. You also need the right pitch, gauge, and number of drive links for your saw. For any saw with a guide bar, gas, electric, or hydraulic, the manual is the correct starting point.

How to Figure Out Which Scenario You're In

The fastest way is to answer three questions. Where does the work happen? Does the tool need to push, pull, or both? Is the main task shaping metal or removing it?

If your crew stays in one bay and the work is bearings, bushings, bending, or straightening, you're in Scenario A. Start with the tonnage and pump style before you settle on a press frame.

If your team travels to the equipment, and you need cylinders to lift, push, or pull at the job site, you're in Scenario B. Focus on the pump power source and whether your cylinders are single-acting or double-acting.

If your work is mostly cutting bolts, rebar, chain, or cable, you're in Scenario C. Decide whether manual or hydraulic cutting fits the volume, then choose cutter blades based on the exact model.

Still not sure? Ask the people who will use it. In my experience, they can tell you within five minutes whether they are pushing, pulling, or cutting. That answer, more than any product sheet, tells you which Enerpac tool deserves a place in your budget.
