The 2SK water-ring vacuum pump is a double-stage model equivalent to two SK pumps in series. As SK series can only reach -700mmHg ultimate vacuum, 2SK is designed for higher vacuum and larger pumping speed in high-vacuum conditions.
The 2SK-P1 two-stage water-ring vacuum pump - air ejector unit operates at 10~50mmHg absolute pressure, but with lower efficiency in high vacuum. For long-term use, a Roots-water ring unit is recommended for optimal high-vacuum pumping efficiency.
2SK pumps/units suck air or non-corrosive, water-insoluble, solid-free gases to create vacuum in sealed containers, suitable for light textile, food, metallurgy, chemical industries in processes like vacuum evaporation, concentration, rewetting, drying, and smelting.

Features
1.Higher vacuum degree and larger pumping speed in high-vacuum zone compared to SK single-stage pumps.
2.Significantly higher shaft power than 2BV/2BE series at the same pumping speed.
3.Dual-impeller structure complicates manufacturing/maintenance with more wearing parts, leading to gradual replacement by 2BV/2BE series.

Note:

1.The performance indicators and curves of the 2SK water-ring vacuum pump listed in the table refer to those under the following specified conditions:

① Atmospheric pressure: 0.1013MPa (760mmHg);

② Inlet water temperature: 15℃;

③ Inhaled air temperature: 20℃;

④ Relative air humidity: 70%.

2.The water supply volume is the value at the suction pressure of -0.05MPa (-400mmHg), which may exceed this value at ultimate vacuum.

3.The allowable performance tolerance is ±10%.
