WORKING THEORY
The SK and 2SK series water ring vacuum pumps are designed for exhausting both non-condensable and condensable gases, such as water vapor. They offer isothermal compression, making them suitable for handling flammable and explosive gases. When constructed with anti-corrosive materials, they can also manage corrosive gases effectively.
The 2SK series two-stage liquid ring vacuum pumps function similarly to two sets of SK series pumps. These models were developed in the 1980s to achieve higher vacuum levels and increased pumping speed under high vacuum conditions, as the SK series only reaches a maximum vacuum of -700 mmHg.
The 2YK series liquid ring vacuum pumps provide better vacuum performance and broader applicability. By selecting the appropriate working medium, they can handle various types of gases efficiently, expanding their range of applications.
These pumps operate smoothly with low noise and energy consumption, offering a 30% energy saving compared to water jet and water vapor jet pumps.

APPLICATION
This pump is ideal for vacuum drying, vacuum degassing, vacuum concentration, vacuum evaporation, and vacuum impregnation processes in industries like chemical, pharmaceutical, metallurgy, food, medicine, textile, papermaking, and electronics. It can be combined with Roots Vacuum Pumps and atmospheric jet pumps to create an efficient vacuum system with high vacuum, high efficiency, and low power consumption.
CURVE
Â
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 1.3×10^4~1×10^5 Pa (between 100 and 760 Torr), please choose series SK Water Ring Vacuum Pump.
(2) If the pump is operated for long time with the inlet pressure range between 5×10^3~1.3×10^4 Pa (between 40 and 100 Torr), please choose series 2SK Water Ring Vacuum Pump.
(3) If the pump is operated for long time with the inlet pressure range between 1×10^3~1.3×10^4 Pa (between 8 and 100 Torr), please choose series 2YK 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 & 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 temperature of supply water should be lower than or equal to 15°C; the highest one should not be higher than 40°C. While 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 be higher than 60°C. When a liquid with a lower boiling point is selected as the working medium under special circumstances, a cooling unit must be equipped to cool down the working media to ensure that the max temperature is 30°C-50°C, lower than the boiling point. For a closed circulation system 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.
Â
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 the non-anti-corrosion pump, the shaft is made of 45# steel or 40Cr, and other parts are made of cast iron or brass;
(2) For the anti-corrosion pump, the parts that the gas passed 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 coating.
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 atmosphere pressure.
When the outlet pressure exceeds 0.15MPa, a special double-stage liquid ring compressor should be chosen instead of a vacuum pump refitted. The power of the equipped motor should be significantly increased, and a special gas-liquid separator and auto-drain unit should be equipped as well.
When the outlet pressure is below 0.15MPa, the vacuum pump can be refitted 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.
Empty Squeeze Tube
An empty squeeze tube is a container that is designed to hold and dispense various types of liquids, gels, and creams. These tubes are typically made of plastic and have a narrow opening at one end that can be sealed with a cap. The other end of the tube is usually tapered and can be squeezed to dispense the contents. Squeeze tubes are commonly used for packaging products such as toothpaste, shampoo, lotion, and other personal care items. Once the contents are used up, the tube can be discarded or recycled.
