With the continuous increase of environmental protection, some enterprises or manufacturers of water ring vacuum pump were forced to stop using this type of vacuum pump due to many sewage discharge. It is necessary to choose oil-free vacuum pump or closed circulation system and large-scale oil-free vacuum unit instead, such as vertical oil-free reciprocating pump and oil-free rotary vane pump, oil-free vertical vacuum pump and oil-free vacuum pump with vacuum High degree, fast pumping speed, no pollution benefits. Because there is no sewage discharge, so the oil-free vertical vacuum pump is especially suitable for chemical, pharmaceutical and food industries, especially in clean high vacuum or gas recovery environment.
The application scale of oil-free vacuum pump is more extensive, which is used in the absorption and transportation of various goods, and the material supply equipment of active machinery. The planning of closed cycle system is to recycle the discharged polluted liquid, which greatly reduces the damage to the environment; the second is to recover the usable medium and reduce the cost of production.
