DESCRIPTION
The 2SK Series Two-Stage Liquid Ring Vacuum Pumps are designed to perform like two sets of SK series water ring vacuum pumps. Due to the limitations of the SK series, which only reach a maximum vacuum of -700 mmHg, China developed the 2SK series in the 1980s to meet the need for high vacuum and large pumping speed under high vacuum conditions.


ADVANTAGE
1. Compared with the SK water vacuum pump, it offers higher vacuum and better pumping speed.
2. Simple structure and easy maintenance.
3. The main working medium is water, resulting in low maintenance costs.
4. It can be used in various areas to handle water vapor, flammable, explosive gases, and gases containing small amounts of dust and liquid.
5. The pump operates well in harsh conditions.

FEATURES
1. The SK and 2SK series water ring vacuum pumps are suitable for exhausting ordinary gases as well as condensable gases (such as water vapor). Because of their isothermal compression characteristics, they can also handle flammable and explosive gases. When made from anti-corrosion materials, they can even be used for corrosive gases.

2. The 2YK series liquid ring vacuum pumps offer higher vacuum levels and broader applicability. By selecting appropriate working media, different types of gases can be pumped, making them suitable for a wider range of applications.

3. These pumps operate smoothly with low noise and energy consumption. They are 30% more energy-efficient compared to water jet and water vapor jet pumps.

PARAMETER

 
APPLICATIONS
This pump can be applied in vacuum drying, vacuum degassing, vacuum concentration, vacuum evaporation, and vacuum impregnation processes across industries such as chemical, pharmaceutical, metallurgy, food, medicine, textile, papermaking, and electronics. It can be combined with Roots Vacuum Pumps and atmospheric jet pumps to achieve high vacuum, high efficiency, and low power consumption.

Regular Selection for Water/Liquid Ring Vacuum Pump
1. Based on the vacuum value
(1) If the pump is operated for long time with inlet pressure between 1.3×10⁴ ~ 1×10⁵ Pa (100 to 760 Torr), choose SK series water ring vacuum pump.
(2) If the pump is operated for long time with inlet pressure between 5×10³ ~ 1.3×10⁴ Pa (40 to 100 Torr), choose 2SK series water ring vacuum pump.
(3) If the pump is operated for long time with inlet pressure between 1×10³ ~ 1.3×10⁴ Pa (8 to 100 Torr), choose 2YK series liquid ring vacuum pump.

2. Working Media
There are four principles to choose working media (i.e., ring liquids):
(1) Lower saturated steam pressure
(2) Lower viscosity
(3) Stable physical and chemical features; no chemical reaction with the pumped gas; no corrosion to the pump; no pollution to the environment.
(4) Economy
When using water as the working medium, the best supply water temperature should be below or equal to 15°C, and the highest should not exceed 40°C. For transformer oil or other low viscosity and saturated vapor pressure industrial oils, the general supply temperature should not exceed 40°C, and the working media inside the pump chamber should not exceed 60°C. In special cases where a liquid with a lower boiling point is used, a cooling unit must be equipped to keep the temperature below the boiling point. For closed circulation systems, a liquid storage unit and cooler must be installed, along with a gas-liquid separator at the outlet. A mechanical seal is recommended for dynamic seals.

3. Choose the dynamic seal of the shaft:
Packing seal is generally used; mechanical seal is preferred for leak-proof occasions.

4. Choose the material of the part that the gas passed:
(1) For non-anti-corrosion pumps, the shaft is made of 45# steel or 40Cr, and other parts are made of cast iron or brass.
(2) For anti-corrosion pumps, the parts that the gas passes through should be made of stainless steel 304 or 306, or other suitable materials, or coated with anti-corrosion coatings.

5. Motor selection based on pumping pressure:
If the pump is used for vacuuming while transferring gas, the outlet pressure exceeds standard atmospheric pressure. When the outlet pressure exceeds 0.15 MPa, a special double-stage liquid ring compressor should be chosen instead of a vacuum pump. The motor power should be increased significantly, and a special gas-liquid separator and auto-drain unit should be equipped. If the outlet pressure is below 0.15 MPa, the vacuum pump can be used as a compressor with an appropriately increased motor power.

6. Composition methods of the water ring vacuum pump system:
An open circulation system should be used if the working liquid in the outlet does not need to be circulated or only partially circulated. A closed circulation system should be used if the working liquid in the outlet must be circulated.
