SZ series liquid ring type vacuum pump and compressor is used to suction or compress air and other gas that is non-corrosive, unsolvable in water and with no solid powder, so that vacuum and pressure can be obtained in the sealed container. However, small amount of liquid is allowed in the suctioned gas. The pump is widely used in several sectors such as mechanical, petrochemical, pharmaceutical, food, sugar making and electronic industry. 

      Since the air compression is operated under the same temperature, it won′t easily lead to any danger, when the pump is suctioning or compressing any flammable or explosive gas. Therefore, the pump is widely used.

Technical parameters:

Note:

 1. When the vacuum percentage range is 40% to 90%, or the pressure range is 0.05Mpa to 0.15Mpa, the gas suction and drainage will be subject to the amount of the supplied water amount and the crevice between the impeller and the side cover. If the flux is rather small, and the adjustment is not accurate enough, the gas suction and drainage tends to be smaller.
 2. The value in the table is obtained under the following condition: ① water temperature is 15℃ ② air temperature is 20℃ ③ relative humidity of the gas is 70％ ④ air pressure is 0.1013Mpa
 3. The performance difference in the table will not exceed 5%
