Pumps of the RCNKu and RCFKu type family are horizontal, single-stage, end-suction, top-discharge centrifugal pumps, standardized to EN 22858, ISO 2858 and ISO 5199. With RCFKu, only the overall length is increased by the amount of the spiral width to ensure a free housing passage. 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. The same applies for the RCKu with open impeller design. The RCFKu is able to handle fluids with larger solids.
