Water ring vacuum pump basics

The water ring vacuum pump (referred to as the water ring pump) is a rough vacuum pump. The ultimate vacuum that can be obtained is 2000~4000Pa, and the series atmospheric injector can reach 270~670Pa. The water ring pump can also be used as a compressor, called a water ring compressor, which is a low pressure compressor with a pressure range of 1 to 2 x 105 Pa gauge.

The water ring pump was originally used as a self-priming pump and was gradually used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry, medicine and food. In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum regain and vacuum degassing, water ring pumps are widely used. Due to the rapid development of vacuum application technology, water ring pumps have been paid attention to in the acquisition of rough vacuum. Since the gas compression in the water ring pump is isothermal, the flammable and explosive gas can be removed, and the dusty and water-containing gas can be removed. Therefore, the application of the water ring pump is increasing.
