Centrifugal Pump 50-32-160 PVDF/EPDM
The RCNKu type is a single-stage horizontal centrifugal pump equipped with a SIC/SICA/ITON mechanical seal system. It is designed with a spacer coupling (back-pull-out version) and mounted on a common baseplate, ensuring ease of maintenance and full compliance with DIN 22858 / ISO 2858 standards.
Key wetted components are made from high-performance thermoplastics (PP, PPH, PVDF, FEP, PEHD), reinforced with metal armouring to provide dimensional stability and mechanical strength. The pump can be fitted with single or double mechanical seals from leading domestic and international brands, making it suitable for handling corrosive liquids containing suspended solids or crystals.
The generously sized shaft, bearings, and closed impeller ensure long service life and high reliability, even in demanding industrial process applications.
