Operating Principle of Claw Technology:
In claw pumps, two claw-shaped rotors run against each other in the housing without contact. Synchronization occurs via gears outside the pumping chamber. This design enables:
- ✓ Absolutely dry running operation without operating fluids
- ✓ No contamination of the medium
- ✓ Minimal wear due to contact-free operation
- ✓ High efficiency and low operating costs
Technical Advantages of Rietschle Claw Pumps:
- ✓ 100% oil and lubricant-free - no contamination
- ✓ Highly efficient - low energy costs in operation
- ✓ Low maintenance - long maintenance intervals, minimal operating costs
- ✓ Reliable - robust construction for continuous operation
- ✓ Compact design - space-saving installation
- ✓ Quiet operation - through precise manufacturing and silencers
- ✓ Environmentally friendly - no oil consumption, no emissions
- ✓ Versatile application - for vacuum, pressure, or both

Why Claw Pumps Instead of Rotary Vane Pumps?
Claw pumps offer decisive advantages over conventional rotary vane pumps:
| Criterion | Claw Pump | Rotary Vane Pump |
|---|---|---|
| Oil-Free | ✓ 100% oil-free | ✗ Requires oil |
| Maintenance | ✓ Very low maintenance | ✗ Regular oil changes |
| Energy Efficiency | ✓ Higher efficiency | ○ Good |
| Operating Costs | ✓ Low | ○ Medium (oil costs) |
| Environmentally Friendly | ✓ No emissions | ✗ Oil disposal required |
| Ultimate Vacuum | ○ 50-250 mbar | ✓ Down to 0.1 mbar |
