Single stage direct liquid ring vacuum pump

* Machine pump coaxial compact design inlet pressure range: 33 ~ 1013mbar (with air injector up to 10mbar); * Reliable operation, superior performance, a variety of material selection, strong corrosion resistance, suitable for various operating conditions. Can handle almost all gases and vapors, can handle a small amount of entrained liquid. Cavitation protection device is optional. Pump structure is reasonable, easy to maintain, no special tools for installation and disassembly. * optional motor: ABs VA series can be equipped with 50 and 60HZ wide voltage motor. Wide range of voltage applicable to different countries/regions. * Low life cost, excellent performance, high efficiency and energy saving; ABs liquid ring vacuum pump is equipped with stainless steel impeller to ensure low maintenance and long downtime maintenance cycle; Special heat treatment is applied to the surface of the disc to reduce the damage caused by cavitation and prevent the disc from rusting and starting after a long stop. * 100% oil-free design without any oil lubrication. Almost isothermal compression, conducive to environmental protection. The shaft does not contact the medium and there is no mechanical contact between the rotating parts.
