LSJ type water jet roots vacuum pump unit, has a large pumping volume, high vacuum degree characteristics, can also be used separately, i.e. when rough vacuum with water jet pump, high vacuum when, then serial up roots pump, limit vacuum can reach 150Pa, water jet pump limit vacuum degree is limited by water temperature, can only reach certain limit vacuum, after serial up roots vacuum pump can reach higher vacuum degree, and the pumping volume is larger than the general mechanical vacuum pump or soda serial injection vacuum pump, suitable for light industry, food, pharmaceutical, oil, pesticides and other industries.

Roots water injection serial vacuum pump unit, ye rots vacuum pump ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot ye rot A ye kë ye cɔl vacuum degree, pumping volume, according to the actual working condition can be divided into sections, water jet pump can work in a rough vacuum state, requiring a high vacuum to start the roots pump, a first level roots can reach 150Pa, a second level roots can reach 30Pa, suitable for light industry, food, pharmaceutical, oil, pesticides and other industries.

F3LSJ type three roots water jet vacuum unit, with faster pumping speed, vacuum higher characteristics, extreme vacuum can reach 2Pa, equipped with electronic control box, the roots pump can achieve automation.
