Model Comparison: Pressure vs. Flow Rate
| Model | Ratio | Max. Pressure | Max. Output | Ideal for |
|---|---|---|---|---|
| 60012 | 12:1 | 84 bar | 36 l/min | Large areas / high rinsing capacity |
| 230027 | 27:1 | 216 bar | 21.6 l/min | Universal cleaning |
| 333037 | 37:1 | 240 bar | 33 l/min | High pressure + good throughput |
| 270049 | 49:1 | 245 bar | 16.5 l/min | Tough buildup / Adhesions |
| 60001 | 1.7:1 (hydraulic) | 247 bar | 33 l/min | Hydraulic operation |
Up to 247 bar
Maximum cleaning performance
Up to 36 l/min
High area coverage
Stainless Steel
Rust & acid resistant
Pro Tip: Start with 60–80% of the maximum permissible inlet pressure (guideline value) and optimize the nozzle angle and distance first – do not increase the pressure immediately.
Professional Workflow
- Choose model based on cleaning goal (throughput or impact)
- Select nozzle 15–25° as a starting point
- Set inlet pressure conservatively
- Test the cleaning pattern
- Adjust pressure step-by-step
- Optional: use foam injection
- Document settings
Conclusion
The right choice of model determines efficiency, safety, and surface quality. With the combination of the correct pressure ratio, flow rate, and properly selected nozzle, you achieve reproducible results – especially in industrial surface preparation.
