2XZ is a two-stage high-speed direct-coupled rotary vane vacuum pump, which is small in size, light in weight, low in noise, easy to start, and is a relatively sophisticated equipment. the pump itself Equipped with a gas ballast valve device to prevent the pump oil from mixing with water, prolong the service life of the pump oil, prevent oil return, prevent oil leakage, and protect the environment clean. The main working parts are immersed in Run in special vacuum pump oil. Therefore, it is not suitable for pumping out oxygen-containing, toxic, explosive, chemically reactive to vacuum pump oil or harmful to vacuum pump oil. Ferrous metals have corrosive gases, and cannot be used as compressors and delivery pumps. The pump can be used alone as a suction pump, or as a booster pump, expansion pump Backing pumps for bulk pumps, molecular pumps, etc., and pre-pumping pumps for maintenance pumps and titanium pumps.
