Primary Mover 200cc Gas-Powered Hydraulic Power Unit
Built to Perform Under Load — Not Just on Paper
Most gas-powered hydraulic units look impressive at no load, but once pressure increases, performance drops off fast. That’s where cycle times slow down and frustration begins.
The Primary Mover 200cc Gas Power Unit was designed to solve that exact problem. After years of selling and supporting traditional 160cc gas units sourced from vendors, we engineered our own system from the ground up — optimized to maintain usable hydraulic flow at real working pressure.
The result is a power unit that stays fast where cheaper units fall off — especially near 3200 PSI, where heavy dump trailers and truck beds actually operate.
Why Flow at High Pressure Matters
Many gas power units advertise high flow numbers, but those ratings are typically measured at very low pressure. In real dump trailer applications, pressure rises quickly, and flow is what determines how fast your bed actually lifts.
The Primary Mover 200cc unit was tested and tuned to maintain strong flow from 0 to 3200 PSI, delivering noticeably faster dump cycles when lifting real weight.
- Up to 80% more flow at 3000 PSI compared to typical 160cc gas units
- Nearly flat flow curve from 0–3200 PSI
- Faster dump cycles under load, not just empty beds
- Reduced engine strain when operating near relief pressure
Real-World Performance Comparison
Below is measured flow data for the Primary Mover 200cc gas power unit. Unlike typical 160cc gas units that lose usable flow as pressure rises, this unit was tested and tuned to maintain strong, consistent output all the way through working pressure and beyond relief.
| Pressure | Primary Mover 200cc Unit | Typical 160cc Gas Unit |
|---|---|---|
| 0 PSI | 10.0 L/min (2.64 GPM) | 2.38 GPM |
| 500 PSI | 10.0 L/min (2.64 GPM) | Flow begins to drop |
| 1000 PSI | 10.0 L/min (2.64 GPM) | 2.25 GPM |
| 1500 PSI | 9.5 L/min (2.51 GPM) | Significant drop |
| 2000 PSI | 9.1 L/min (2.41 GPM) | 2.11 GPM |
| 2500 PSI | 9.1 L/min (2.41 GPM) | Minimal usable flow |
| 3000 PSI | 9.0 L/min (2.38 GPM) | 1.32 GPM |
| 3200 PSI | 9.0 L/min (2.38 GPM) | Unable to sustain operation |
| 3500 PSI | 8.8 L/min (2.32 GPM) | Not achievable |
What this shows: the Primary Mover 200cc unit maintains a nearly flat flow curve from 0 to 3200 PSI and continues operating past relief, which is exactly where heavy dump trailers and truck beds spend most of their time.
Ideal Applications
- Heavy dump trailers
- Dump truck beds
- Scissor hoists operating near relief pressure
- Applications where faster cycle times improve productivity

Frequently Asked Questions
(Click to expand)
How is this different from a standard 160cc gas power unit?
Traditional 160cc units are designed to look strong at low pressure, but flow drops sharply as pressure increases.
The Primary Mover 200cc unit was engineered specifically to maintain usable flow near 3200 PSI, resulting in faster dump cycles under real load.
Will this make my dump trailer lift faster?
Yes — especially when lifting heavy material. Because this unit maintains higher flow at working pressure, it reduces total dump time compared to standard gas units.
Why does my current gas unit feel slow with a heavy load?
As load increases, pressure rises. Many gas units lose most of their flow at higher pressure, which dramatically slows the lift speed.
This unit is designed to stay fast where others fall off.
Is this unit designed for continuous heavy use?
Yes. The 200cc engine and tuned hydraulic system reduce engine strain when operating near relief pressure, making it ideal for frequent heavy dumping.
Is this the right power unit for my application?
If your application involves lifting real weight and operating near 3000–3200 PSI, this unit is an excellent choice. If you’re unsure, our team can help verify compatibility.
