Roots vacuum pump of application

The great advantage of Roots Vacuum Pump is that it has a higher pumping rate at lower inlet pressure, but it can not be used alone. It must be connected in series with a front-stage vacuum pump. In this case, Roots vacuum pump is not allowed to work under high pressure difference, otherwise it will be overloaded and overheated and damaged, so the use of Roots vacuum pump must be reasonable selection of the front vacuum pump, installation of necessary protection equipment.water-ring-vacuum-unit
