1. Product introduction
SK series water ring vacuum pump and compressor are used to pump or press gas and other non corrosive, water-insoluble and solid particle free gases, so as to form vacuum or pressure in closed containers and meet the requirements of process flow. A small amount of liquid is allowed to be mixed in the inhaled or compressed gas.

3. Scope of application
SK series water ring vacuum pumps are widely used in petrochemical, pharmaceutical, food, sugar industry and other fields. Because the gas compression process is isothermal in the working process, it is not easy to cause danger when compressing and pumping flammable and explosive gases, and its application is more extensive.
4. Product Features
(1) During the working process, the work will generate heat, which will heat the working water ring, and some water and gas will be discharged together. Therefore, during the working process, the pump must be continuously supplied with water to cool and supplement the water consumed in the pump.
(2) Mechanical seal can be used for sealing, which is installed in the packing chamber, and the packing is omitted. The packing gland is replaced with a mechanical seal gland, and the other structures are the same as those of the packing seal.
(3) A disc is installed on the end cover. The disc is provided with a suction hole, an exhaust hole and a rubber ball valve.
