Pumps of the CPDR and CPRF type family are horizontal, single-stage, end-suction, top-discharge centrifugal pumps, standardized to EN 22858 (formerly DIN 24256; ISO 2858 and ISO 5199). The installation length of type CPRF is simply longer about the channel width so that a free passage for the fluid is given. The pumps are used for handling chemically aggressive and/or inflammable liquids within the wide field of chemical processing and environmental technology. The CPDR with open impeller is foreseen for clean liquids and fluids with a small content of solids. The CPRF is able to handle fluids with larger solids. Both types are possible in close-coupled design instead of bearing block.
