High Quality Water Ring Vacuum Pump for Lab

High Quality Water Ring Vacuum Pump for Lab


2SK series two-stage liquid ring vacuum pumps can function effectively like two sets of SK series water ring vacuum pump. Due to SK sequence vacuum pumps only get to the optimum vacuum of-700mmHg, to meet up with the higher vacuum and the massive pumping pace underneath substantial vacuum, China created the 2SK collection drinking water ring vacuum pump in 80s in the 20th century. 


1. When compared with SK drinking water vacuum pump ,It receives high vacuum and pumping pace etc..

two. Basic framework and straightforward maintenance.

3. The mostly doing work medium is h2o and minimal upkeep expenses.

4.The pump is widely use in several regions and suction h2o vapor,flammable, explosive and various gases have a modest sum of dust and liquid.

5. The pump can performs in the harsh issue


one. Sequence SK,2SK H2o Ring Vacuum Pumps can be utilized to exhaust normal gases as properly as condensable gases(such as h2o vapor). Because they have the attributes of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion materials is picked, it can be used for exhausting corrosive gases too.


2. Collection 2YK Liquid Ring Vacuum Pumps have the functions of larger vacuum and better applicability. The different types of gases can be pumped with the picked ideal doing work media. As a result, they can be utilized in broader selection.


3. The pumps run efficiently with lower sounds and usage. The power-saving is 30 percent comparing with the H2o Jet and the Water Vapor Jet Pumps.

It can be applied to the vacuum drying, vacuum degassing, vacuum concentration, vacuum evaporation, vacuum impregnation process in chemical, pharmaceutical, metallurgy, food, medicine, textile, papermaking, electrical industry ( electronic industrial field) and so on. It can compose a vacuum system together with Roots Vacuum Pump and atmospheric Jet pump to achieve high vacuum, high efficiency, low power consumption.

Regular Selection for Water(Liquid)Ring Vacuum Pump
1,Based on the vacuum value
(one)If the pump is operated for long time with the inlet pressure range between1.3×104~1×105Pa (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 between5×103~one.3×104Pa(between40 and 100 Torr), please choose series 2SK Water Ring Vacuum Pump.
(three)If the pump is operated for long time with the inlet pressure range between1×103~one.3×104Pa(between8 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)
(one) Lower saturated steam pressure
(2) Lower viscosity
(three) Stable physical & chemical features no chemical reaction with the pumped gasno corrosion to the pump no pollution to the environment.
(four) Economy

      If the water is chosen as the operating medium, the greatest temperature of offer water should be lower than or equivalent to fifteen °C the greatest one must not be greater than 40°C. Although the transformer oil or other low viscosity and saturated vapor stress industrial oils are as the doing work media, the basic supply temperature should not larger than 40°C and the functioning media temperature within the pump chamber must not be larger than 60C, when the liquid with decrease boiling position is picked as the working media beneath some specific conditions, the cooling device have to be equipped to great down the operating media in buy to make sure that the max temperature is 30ºC-50ºC, reduced than the boiling point. For the shut circulated method of operating media, the liquid storage unit and cooler have to be outfitted, and the gasoline-liquid separator need to be mounted at outlet. The mechanical seal should be employed for dynamic seal of the shaft.

three,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:

(one) For the non anti-corrosion pump, the shaft is created of 45#metal or 40Cr, other elements are made of solid Iron or brass

(two) For the anti-corrosion pump,the areas that the fuel passed, should be created of stainless steel 304 and 306, or other substance suited for the respectively corrosive gasoline, or the components must be put with anti-corrosion coating.

5, The motor should be selected based on pumping pressure.

If the pump is utilised for vacuuming while transferring gas, the strain of pump outlet exceeds the CZPT atmosphere force.

When the outlet pressure exceeds .15MPa, the particular double-phases liquid ring compressor must be chosen and not the vacuum pump refitted. Tthe power of the outfitted motor should be increased naturally. And the specific gas-liquid separator and vehicle-drain device should be geared up also.

When the outlet force is underneath .15MPa, it can use the vacuum pump refitted as compressor. The power of the outfitted motor need to be increased appropriately.

six,Composition methods of the water ring vacuum pump system
The opening 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.
