With the MNK 200–150–315 (flow rates of up to 600 m³/h) Richter Chemie-Technik has an efficient PFA/PTFE-lined magnetic drive pump in its range. At Wacker Chemie this pump has been undergone a practical test since December 2007, conveying a very corrosive mixture consisting of acetic acid, formic acid and acetaldehyde at temperatures of up to 80 °C. The MNK 200–150–315 is designed as a single-stage, sealless chemical centrifugal pump of heavy-duty, horizontal design. All components which come into contact with the medium either have a thick PFA and PTFE fluoroplastic lining, are made of solid PTFE fluoroplastic or of sintered silicon carbide SSiC. The Safe-glide Plus plain bearing system prevents damage in the event of brief dry-running.
