本型泵系雙級油封機械變容真空泵，它具有向大氣直接排氣的特點，適用于電子、制冷、電光源、化工、醫療、瓶膽、包裝、脫水、干燥等行業。（但不能用于抽除含氧過高的、有爆炸性的、對金屬有腐蝕性的、對真空油起化學反應的以及含有顆粒，塵埃的氣體，也不能作為輸送泵及壓縮泵使用）。
This type of pump is two-stage oil-sealed mechanical displacement pump, which has a direct exhaust gas to the atmosphere, suitable for electronics, refrigeration, electric light, chemical, medical, bottle lamps, packaging, dehydration, drying and other industries. (But not for the high oxygen extraction, explosive, corrosive to metal, the vacuum oil from the chemical reaction and containing particles, dust, gas, and not as a pump and compressor pumps).
