2SK Series Two-Stage Water Ring Vacuum Pump is equivalent to two SK series water ring vacuum pumps connected in series.
Since the SK series water ring vacuum pump can only achieve an ultimate vacuum of -700mmHg, the 2SK series vacuum pump was developed domestically in the 1980s to achieve higher vacuum levels and greater pumping speeds under high vacuum conditions. With the emergence of the new generation of energy-efficient products such as the 2BV and 2BE1 series, the 2SK series will gradually be phased out.
The 2SK-P1 series two-stage water ring vacuum pump - atmospheric ejector pump unit primarily operates in the absolute pressure range of 10~50mmHg, but its efficiency is lower in the high vacuum region. For long-term operation, a Roots water ring vacuum unit can be selected to achieve optimal pumping efficiency in the high vacuum region.
Main Features:
Compared to the SK series single-stage water ring vacuum pump, it offers higher vacuum levels and greater pumping speeds in the high vacuum region.
At the same pumping speed, the shaft power is significantly higher than that of the 2BV and 2BE1 series.
Due to its dual-impeller structure, manufacturing and maintenance are more complex, and there are more vulnerable parts.

The power of the 2SK-P1 series two-stage water ring vacuum pump - atmospheric ejector pump unit is the same as that of the 2SK series, with an ultimate vacuum of -750mmHg. The pumping speed can be seen in the performance curve (left section).
Note:
I. The performance indicators and performance curves listed in the table refer to the performance under the following specified conditions:
1. Atmospheric pressure of 0.1013MPa (760mmHg)
2. Inlet water temperature of 15°C
3. Suction air temperature of 20°C
4. Relative humidity of air at 70%
II. The water supply is the value at a suction pressure of -0.05MPa (-400mmHg), and it may be higher at the ultimate vacuum.
III. Performance tolerance ±10%
