SPECIFICATION
Product Name: Water Ring Vacuum Pump
Note: For detailed model specifications, please refer to the actual product.WORKING THEORY
1. The SK and 2SK series water ring vacuum pumps are suitable for exhausting both ordinary gases and condensable gases (such as water vapor). These pumps have the advantage of isothermal compression, making them ideal for handling flammable and explosive gases. If made from corrosion-resistant materials, they can also be used for exhausting corrosive gases.
2. The 2SK series two-stage liquid ring vacuum pumps operate similarly to two sets of SK series water ring pumps. Since the SK series only reaches a maximum vacuum of -700 mmHg, the 2SK series was developed in the 1980s to meet the need for high vacuum and large pumping speed under such conditions.
3. 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, allowing for a wider range of applications.
4. These pumps operate smoothly with low noise and energy consumption. They are 30% more energy-efficient compared to water jet and steam jet pumps.
ADVANTAGE
1. Compared to SK water vacuum pumps, it achieves higher vacuum and pumping speed.
2. Simple structure and easy maintenance.
3. The primary working medium is water, resulting in low maintenance costs.
4. Widely used in many areas, capable of suctioning water vapor, flammable, explosive, and various gases containing small amounts of dust and liquid.
5. Can operate in harsh conditions.

5. The pump can work in harsh conditions.
Regular Selection for Water (Liquid) Ring Vacuum Pump
1. Based on the vacuum value
(1) If the pump is operated for long time with the inlet pressure range between 1.3×10â´~1×10âµ Pa (between 100 and 760 Torr), choose the SK series water ring vacuum pump.
(2) If the pump is operated for long time with the inlet pressure range between 5×10³~1.3×10ⴠPa (between 40 and 100 Torr), choose the 2SK series water ring vacuum pump.
(3) If the pump is operated for long time with the inlet pressure range between 1×10³~1.3×10ⴠPa (between 8 and 100 Torr), choose the 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
If water is selected as the working medium, the best supply water temperature should be lower than or equal to 15°C; the highest should not exceed 40°C. When transformer oil or other low viscosity and saturated vapor pressure industrial oils are used as the working media, the general supply temperature should not exceed 40°C, and the working media temperature inside the pump chamber should not exceed 60°C. In special cases where a liquid with a lower boiling point is selected as the working medium, a cooling unit must be equipped to cool the working media to ensure that the maximum temperature is between 30°C-50°C, which is below the boiling point. For closed circulation systems of working media, a liquid storage unit and cooler must be equipped, and a gas-liquid separator must be installed at the outlet. A mechanical seal should be used for the dynamic seal of the shaft.
3. Choose the dynamic seal of the shaft:
Choose the packing seal in general occasions; choose the mechanical seal when the pump is used in a no-leak occasion.
4. Choose the material of the part that the gas passed:
(1) For non-corrosion-resistant pumps, the shaft is made of 45# steel or 40Cr, and other parts are made of cast iron or brass;
(2) For corrosion-resistant pumps, the parts that the gas passes through should be made of stainless steel 304 and 306, or other materials suitable for the respective corrosive gas, or the parts should be coated with anti-corrosion coatings.
5. The motor should be selected based on pumping pressure.
If the pump is used for vacuuming while transferring gas, the pressure of the pump outlet exceeds the 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 power of the equipped motor should be increased significantly. Additionally, a special gas-liquid separator and automatic drainage unit should be equipped.
When the outlet pressure is below 0.15 MPa, the vacuum pump can be used as a compressor. The power of the equipped motor should be increased appropriately.
6. Composition methods of the water ring vacuum pump system
The open circulation system should be used if the working liquid in the outlet need not be circulated or partially circulated.
The closed circulation system should be used if the working liquid in the outlet must be circulated.
APPLICATIONS
Widely used in papermaking, chemical, petrochemical, light industry, pharmaceutical, food, building materials, electrical appliances, coal washing, and mineral dressing industries, fertilizer, etc.
In the coal industry, it can especially pump highly flammable and explosive gas, such as mash gas, methane, and can design installation of ground gas drainage station, forming a complete set of mobile gas drainage system.
