RCNKu⁺

Standardized chemical pump in plastic

Pumps of the RCNKu⁺ type family are horizontal, single-stage, end-suction, top-discharge centrifugal pumps, standardized to EN 22858 and ISO 5199. The pumps are used for handling chemically aggressive and/or inflammable liquids within the wide field of chemical processing and environmental technology. The RCNKu⁺ with closed impeller is foreseen for clean liquids and fluids with a small content of solids.
