7-DE Diesel Hydraulic Power Pack
Reliable Power for Rock Splitters Anywhere on Site
A hydraulic rock splitter is only as good as the power behind it. On a quarry face, a remote trench or a demolition site, there is often no mains electricity nearby, and waiting for a connection wastes hours. A diesel-driven power pack solves that problem. The 7-DE Diesel Hydraulic Power Pack gives your splitter the pressure it needs, right where you are working, with nothing more than a tank of diesel.
It is compact, easy to move around, and built to handle high hydraulic pressure for long working hours. Here is what it offers and how it fits into your setup.

What Is the 7-DE, Really?
Think of the power pack as the heart of the system. A diesel engine drives a hydraulic pump, the pump pushes oil at high pressure through the hoses, and that pressure is what makes the splitter's wedges open the rock. The 7-DE Diesel Power Pack puts the engine, pump, tank and controls in one frame, so you can set it down near the work and start.

How the Power Pack Works
Once the engine is running, the pump draws oil from the tank and sends it under pressure through the hose to the splitter. When you operate the control, the oil pushes the splitter's wedge forward and the rock cracks. When you release it, the oil returns to the tank and the wedge retracts. In simple terms, the 7-DE Hydraulic Power Pack turns engine power into the hydraulic pressure that does the splitting.
A normal setup looks like this:
- Place the power pack on firm, level ground close to the work area.
- Check the fuel and hydraulic oil levels.
- Connect the hoses to the splitter and make sure the couplings are fully locked.
- Start the engine and operate the control to run the splitter.
One tip: keep the hoses as short and straight as the site allows. It cuts pressure loss and makes it easier to keep an eye on the whole line.
Where You Can Use It
The 7-DE is useful anywhere a splitter needs to work away from a mains supply. As a 7-DE Rock Splitter Power Pack, it runs hand-held rock splitters such as the S36s, S90 and S240, so you can break boulders, slabs and concrete without depending on site electricity. It also suits remote quarries, hillside jobs and temporary demolition sites.
Why a Diesel Power Pack Makes Sense
Site power is rarely where you need it. With a diesel unit, you set up where the rock is, not where the socket is. That saves time on cabling, and it keeps the splitter working even when the site has no reliable electricity.
It also means the whole setup can be moved as the job moves. On a large quarry or a long trench, that makes a real difference.
Prepare Before You Begin
A few minutes of preparation prevents most problems on site:
Safety and Maintenance
Regular care keeps the power pack dependable, job after job.
Compact Enough to Move Around
At about 125 kg and 1200 mm long, the 7-DE is far easier to reposition than a large stationary unit. It takes up little space near the work face, and you can shift it along as the splitting line moves. Setting up at a new spot takes minutes, not hours.
Who Uses the 7-DE?
Buying a Power Pack: What to Check
If you are looking for a 7-DE Power Pack Supplier, ask for the engine rating, the maximum working pressure and the number of splitters the unit can run. It also helps to confirm which splitter models it suits, and whether spare hoses, couplings and service support are available. A good match between the power pack and the splitter is what keeps the whole system reliable.
