**Technical Parameters (2SK Series Double-Stage Liquid Ring Vacuum Pump):**
| Model | Suction Amount (m³/min) | Ultimate Pressure (MPa) | Power (kW) | Rotating Speed (r.p.m.) | Water Flow (L/min) | Suction Port Diameter |
|-------|--------------------------|-------------------------|------------|--------------------------|--------------------|------------------------|
| 2SK-1.5 | 1.5 | 0.9 | -730 | -0.097 | 4 | 1440 | 1015 | φ40 |
| 2SK-3 | 3 | 2 | -735 | -0.098 | 7.5 | 1440 | 1520 | φ40 |
| 2SK-6 | 6 | 4 | -735 | -0.098 | 15 | 1460 | 2535 | φ70 |
| 2SK-12 | 12 | 8 | -735 | -0.098 | 22 | 970 | 4050 | φ100 |
| 2SK-30 | 20 | 14 | -735 | -0.098 | 45 | 740 | 6080 | φ125 |
| 2SK-30 | 30 | 20 | -735 | -0.098 | 55 | 740 | 7090 | φ125 |
**Note:**
1. The values are obtained under the following conditions: Air pressure is 0.1013 MPa (760 mmHg), inlet water temperature is 20°C, relative air humidity is 70%.
2. The values are measured when the supplied water flow is at a suction pressure of 0.05 MPa (400 mmHg). It can be higher when reaching ultimate vacuum.
3. Performance differences will not exceed ±10%.
