ZJ type Roots vacuum pump

The ZJ type Roots vacuum pump, due to the use of CNC machining centers, is sealed with "O" rings between the pump body and the side cover, as well as between the side cover and the end cover, with cylindrical pin positioning. It has good parts interchangeability and easy maintenance. The pump adopts a structural design of one inlet and three exhaust ports, which is convenient for users to install and use. Roots pumps cannot be used alone, only series connected front-end pumps can be used. Screw pumps, oil seal pumps, and liquid ring pumps can be selected as front-end pumps. It is worth mentioning that when screw pumps and liquid ring pumps are used as front-end pumps, they are particularly suitable for extracting large amounts of suspicious gases.
