JSC “HMS Livgidromash” in order to meet the needs of consumers continues to expand the range of serially manufactured vacuum water ring pumps of type VVN - serial production of VVN2-50 pumps has been started.
Vacuum water ring pumps VVN2-50 and plants that are based on them are designed with the purpose of creating or maintaining a vacuum depending on the material of the flow part, suction, inert or insoluble in water aggressive gases.
Pumps are general-purpose product, recoverable according to GOST 27.003. Pumps available in climatic class U or T for location category 2, 3.1 according to GOST 15150. Shaft sealing: packing gland.
The drive in the units is electric motors of general industrial design.
Application:
chemical, mining, metals, coal, food, pulp and paper industries, agriculture, construction and medicine.
