Liquid-packed ring-type vacuum pumps

Depending on material of inner flowing part designed for pumping (creation of vacuum ) of air, inert or aggressive gases, insoluble in water, to produce or maintain vacuum. Operating medium - water.

Application: chemical, ore mining and smelting industry, food industry, pulp and paper industry, agriculture, construction and medicine.

Main advantage of pumps - easy operation and maintenance. Pumps consist of small quantity of parts. They have no special system for lubrication and oil pumps. All clearances between rotor and static casing are sealed with operating medium. Simplicity of construction, no friction pairs in inner flowing part provide reliability and service life of pump operation.
