Hydraulic Power Packs

A hydraulic power pack is a self-contained, engine-driven hydraulic supply — a gas engine, pump, reservoir, and controls on a portable frame. It lets you run hydraulic tools and attachments anywhere, without a tractor, skid steer, or excavator to feed them. Contractors use them for breakers, post drivers, cutters, and pumps on sites where no carrier machine is available or where dragging a full-size machine in makes no sense.

Sizing a Power Pack: Pressure and Flow

Two numbers decide whether a power pack will run your tool. Get both from the tool's spec plate before you buy.

• Pressure (PSI): Determines the force the tool can generate. A tool rated for higher pressure than your pack supplies will run weak or not at all.
• Flow (GPM): Determines speed — how fast the tool cycles or the motor turns. Undersized flow means sluggish operation; oversized flow can overheat or damage a tool not rated for it.
• Match both, not one: A pack that meets your pressure requirement but falls short on flow will disappoint. Tools list a range for each — stay inside it.
• Reservoir capacity: Larger reservoirs shed heat better on long continuous runs. Small tanks are fine for intermittent work.

What Else to Look For

• Recoil vs. electric start: Recoil is simpler and lighter with nothing to go dead. Electric start earns its keep on larger engines and cold mornings, and when the pack lives on a trailer.
• Circuit type: Confirm whether your tool needs an open-center or closed-center circuit, and whether it requires a return line, a case drain, or both.
• Couplers and hose: Flat-face couplers stay cleaner and are easier to connect under residual pressure. Verify coupler size and style matches your tool.
• Frame and portability: Roll cages, lift eyes, and skid frames matter when the pack has to go up stairs, into a trench, or onto a truck bed daily.

Frequently Asked Questions

How do I know which power pack my tool needs?

Check the tool's data plate or manual for its required operating pressure and flow range, then pick a pack that falls inside both. If the tool lists a maximum flow, do not exceed it — too much flow generates heat and can damage seals and motors.

Can a power pack replace a skid steer or excavator for running attachments?

For handheld and stationary hydraulic tools, yes — that is exactly what it is for. For attachments that need a carrier machine to position and apply down-pressure, like a breaker on a boom, a power pack supplies the hydraulics but not the machine. It is the right answer when you need hydraulic power in a spot a carrier cannot reach.

What hydraulic fluid should I run?

Follow the manufacturer's specification in the manual for the pack you buy. Fluid viscosity affects pump life and cold-weather startup, so do not substitute based on what is on the shelf, and change it on the recommended interval.
