The 2BV stainless steel vacuum pump is suitable for extracting gases and steam vapor, with an aspiration pressure that can reach 33mbar absolute pressure (97% vacuum). When the vacuum pump operates under an aspiration pressure below 80mbar for an extended period, it should be connected to an air-eroding protection pipe to protect the pump. If an atmospheric jet ejector is used, the aspiration pressure can reach 10mbar, and the ejector can be directly mounted on the vacuum pump. When used as a compressor, the maximum pressure is up to 0.26MPa (absolute pressure).

The 2BV stainless steel vacuum pump is corrosion-resistant, but we should still pay attention to the following points during use to extend its service life:

1. Ensure the stainless steel vacuum pump operates as close to the operating range as possible, which is within the critical vacuum or critical exhaust pressure area.

2. Avoid operation near the highest vacuum level or maximum exhaust pressure. Operation within this area is not only inefficient but also highly unstable, prone to vibrations and noise.

3. For stainless steel vacuum pumps with high vacuum levels, although made of stainless steel, cavitation often occurs within this region. The clear sign of this is noise and vibration within the pump.

4. Cavitation can lead to damage of parts such as the pump housing and impeller, rendering the pump inoperable.
