Water ring vacuum pumps VVN type
Water ring vacuum pumps VVN type are designed (depending on the material of the flow path) for suction of air, inert or aggressive gases, insoluble in water, in order to create or maintain a vacuum.
The working fluid is water.

They are used in the chemical, mining and metallurgical, coal, food, pulp and paper industries, agriculture, construction and medicine.

• coupling connecting the ends of the shafts;
• drainage basin (if provided by the design);

• a set of spare parts, tools and accessories;
• technical documentation.
