Darda Hydraulic Power Packs — Gas, Electric, Air & Diesel
The engine room of every hand-held Darda system: a two-stage pump runs the wedge out fast at low pressure, then delivers the split at 7,250 psi — and every pack connects up to three splitters or shears at once. Five power systems cover every site from occupied buildings to underground headings.
The short version
Match the pack to the site: BP3 gas for everyday surface work, EP3 110V electric indoors and at night, AP3 air underground and in refineries, D4 diesel (electric start optional) for quarry duty. Buying your first Darda? A complete splitter kit pairs the pack with the cylinder. Compare all brands in Hydraulic Power Packs, or start at the Darda hub. Above 5,000 ft on gas? Add the high-altitude kit. Call 1-888-883-5144 to size it.
One Pack, Five Power Systems
Darda Hydraulic Power Pack
Wheeled and handle-barred for one-person moves, with a manifold block and pressure gage, oil level and temperature display, return-line filter, and a lockout against third-party start-up. The two-stage pump gives 1.3 GPM of fast low-pressure travel and 0.4 GPM at the full 7,250 psi (the D4 diesels push 1.4 GPM at high pressure for multi-tool work).
Choose it when: you buy a cylinder bare, add a second pack to the fleet, or need a different power source for a new site — every pack runs any Darda splitter or the HCS8 shear.

Power Pack Questions, Answered
Which Darda power pack should I choose?
By site, not by spec: the BP3 gas (Honda engine, from $13,265) is the everyday surface pick; the EP3 110V electric runs indoors, at night, and in occupied buildings with no exhaust; the AP3 compressed-air pack belongs underground and in refineries where engines are unwelcome; and the D4 diesel — with optional electric start — is the quarry workhorse with a stronger 1.4 GPM high-pressure stage and a side mount for transporting splitters.
How many splitters can one pack run?
Every pack has a manifold for up to three tool connections — splitters, the HCS8 shear, or a mix. The D4 E stretches to five connections with the optional manifold and the S2–S5 hose sets. That is why adding a bare cylinder to an existing pack is the cheapest way to grow a splitting crew.
What pressure and flow do these packs deliver?
Two stages: about 1.3 GPM at low pressure to run wedges out fast, then 0.4 GPM at the working pressure of 7,250 psi (50 MPa) to make the split — the D4 diesels deliver 1.4 GPM at high pressure. An oil-level indicator with temperature display, a return-line filter, and a pressure gage on the manifold keep the system honest.
Do I need the BP3 high-altitude kit?
If you run the BP3 gas pack anywhere above roughly 5,000 ft, yes: the $152.98 carburetor kit keeps the Honda engine running right at elevation — the factory rates standard carburetion to about 5,000 ft (1,500 m). Electric, air, and diesel packs do not care about altitude the way a carbureted gas engine does.
Will a Darda power pack run other hydraulic tools?
It is purpose-built for the Darda system: 7,250 psi is far above the 1,500–2,500 psi that common hydraulic breakers and pumps expect, and the two-stage flow profile is tuned to splitter cylinders and the HCS8. Run Darda tools on Darda packs; if you need general-purpose hydraulic power, call us and we will point you at the right pack for that tool instead.
