Vacuum pumps
Depending on material of flow part, water packed vacuum pumps are designed for suction (vacuum production) of air, aggressive or inert gases insoluble in water, in order to create or maintain vacuum.
Operating fluid is water.
Scope of application: chemical, mining, coal, food, pulp and paper industries, agriculture, engineering and medical industry.
The main advantage of pumps is easy operation and maintenance. Pumps have no special lubrication systems and oil pumps. All gaps between rotating rotor and stationary casing are sealed with operating fluid. The simplicity of design, absence of friction pairs in flow part provides reliability and durability of pump operation.
