1. Product introduction
2BV/SKA series water ring vacuum pump is suitable for pumping out gas and water vapor. The suction pressure can reach 22mbar absolute pressure (97% vacuum degree). When the vacuum pump works for a long time under the condition that the suction pressure is lower than 80mbar, a cavitation protection pipe should be connected to protect the pump. When it is used as a compressor, the maximum pressure is 0.26mbar absolute pressure.

3. Scope of application
2BV/SKA 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) The water ring vacuum pump is designed with coaxial direct connection, which saves space and is easy to install.
(2) The mechanical seal is used as the standard device to eliminate leakage and facilitate maintenance.
(3) The operation is stable and the noise can be as low as 62 decibels.
(4) Uniform corrosion resistance design, bronze impeller improves the corrosion resistance of the pump, and stainless steel material is more suitable for more demanding applications.
(5) The unique flexible exhaust port design will not produce over compression, ensuring the best efficiency of 2BV/SKA within its performance range.

6. Specifications
Note: 1. The modified performance parameters are obtained when the suction medium is 20 ℃ saturated air, the working fluid temperature is not more than 15 ℃, and the exhaust pressure is 1013 mbar. The allowable performance deviation is ± 10%.
