ZJP series vacuum pump is a roots vacuum pump that can be used in vacuum smelting, vacuum welding, vacuum spraying, vacuum drying, vacuum power experiments, chemical pharmaceuticals, electric vacuum device manufacturing and other vacuum treatments within the vacuum range that this type of pump can achieve. This pump is able to get a higher pumping rate at a lower inlet pressure and achieve a higher ultimate vacuum, so it can meet the vacuum requirements of different industries.
