SPECIFICATION
Products Name: Water Ring Vacuum Pump
PS: Detailed model refer to REAL PIECE pls.WORKING THEORY1. Series SK, 2SK Water Ring Vacuum Pumps can be used to exhaust ordinary gases as well as condensable gases (such as water vapor). Because they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion material is selected, it can be used for exhausting corrosive gases too.
Â
2SK series two-stage liquid ring vacuum pumps can work well like two sets of SK series water ring vacuum pump. Due to SK series vacuum pumps only reach the maximum vacuum of -700 mmHg, to meet the high vacuum and the large pumping speed under high vacuum, China developed the 2SK series water ring vacuum pump in the 80s of the 20th century.
Â
2. Series 2YK Liquid Ring Vacuum Pumps have the features of higher vacuum and better applicability. The different types of gases can be pumped with the selected suitable working media. Therefore, they can be applied in a wider range.
Â
3. The pumps run smoothly with low noise and consumption. The energy-saving is 30 percent compared with the Water Jet and the Water Vapor Jet Pumps.

ADVANTAGE
1. Compared with SK water vacuum pump, it gets high vacuum and pumping speed etc.
2. Simple structure and easy maintenance.
3. The mostly working medium is water and low maintenance costs.
4. The pump is widely used in many areas and can suction water vapor, flammable, explosive and various gases containing a small amount of dust and liquid.
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), please choose series SK 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), please choose series 2SK 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), 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 the 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 the transformer oil or other low viscosity and saturated vapor pressure industrial oils are as the working media, the general supply temperature should not be higher than 40°C and the working media temperature inside the pump chamber should not be higher than 60°C. When the liquid with lower boiling point is selected as the working media under some special circumstances, the cooling unit must be equipped to cool down the working media in order to ensure that the max temperature is 30°C-50°C, lower than the boiling point. For the closed circulated system of working media, the liquid storage unit and cooler must be equipped, and the gas-liquid separator must be installed at outlet. The mechanical seal should be used for dynamic seal of the shaft.
3, Choose the dynamic seal of the shaft:
Choose the packing seal in general occasion; choose the mechanical seal when the pump is used in no leak occasion.
4, Choose the material of the part that the gas passed:
