⚙️ Operating Principle – Scroll Technology:
How ISP Scroll Pumps Work:
- Two spiral scrolls – one fixed scroll, one orbiting scroll
- Eccentric orbiting motion – orbiting scroll moves in circular path without rotating
- Multiple gas pockets form between the scrolls
- Gas is trapped at outer periphery
- Pockets move inward as orbiting scroll moves, volume decreases continuously
- Gas is compressed progressively toward center
- Discharge occurs at center port when pocket reaches minimum volume
- Continuous process – multiple pockets at different compression stages simultaneously
💡 Why Scroll Technology is Ideal:
| No Metal Contact |
Scrolls don't rub against each other = no wear, no lubrication needed |
| Continuous Compression |
Smooth, pulsation-free operation = quiet and efficient |
| Multiple Compression Stages |
Several gas pockets at different pressures = efficient compression |
| Simple Design |
Few moving parts = high reliability, minimal maintenance |

🔧 Installation & Operation:
📐 Installation Requirements:
- ✓ Level surface – place on flat, stable surface
- ✓ Ventilation space – allow 10 cm clearance on all sides for cooling
- ✓ Power supply – verify correct voltage (100-240V AC)
- ✓ Inlet connection – use appropriate hose/tubing size
- ✓ Exhaust routing – ensure exhaust is not blocked
- ✓ Vibration isolation – use rubber pads if needed (included on most models)
⚡ Operating Guidelines:
- ✓ Check power supply voltage matches pump specification
- ✓ Start pump before opening vacuum valve to chamber
- ✓ Allow pump to warm up for 1-2 minutes before full load
- ✓ Monitor operating temperature – should remain stable
- ✓ Keep inlet filter clean (if equipped)
- ✓ Avoid pumping liquids – use cold trap if condensates present
- ✓ Don't block exhaust port
🔧 Maintenance & Service Life:
📅 Minimal Maintenance Schedule:
| Task | Interval | Description |
|---|
| Visual Inspection |
Monthly |
Check for unusual noises, vibrations, or temperature |
