Mechanical seal, has a simple structure, easy installation, no oil, safe and reliable shaft. 2BV series water ring vacuum pump suitable for pumping gas and wet steam, suction pressure can reach 33mbar absolute pressure (97% vacuum), when the suction pressure 2BV type water ring vacuum pump is less than 80mbar work under long-term conditions, should is connected to the protective tube pump cavitation protection, 2BV water ring vacuum pump, such as an air ejector pump suction pressure reaches 10 mbar, the injector can be mounted directly on the pump suction port, used in a compressor, pressure up to 0.26MPa (absolute pressure). 2BV series water ring vacuum pumps and compressors are widely used in petroleum, chemical, pharmaceutical, food and sugar industries. During the operation, the gas isothermal compression, so the compression and pumping flammable gas, is not easy to explode, so its wider application.
