Chemical centrifugal pump in plastic

Vertikale Chemie-Pumpe aus Kunststoff
RVKu Chemie-Pumpe aus Kunststoff
Chemie-Kreiselpumpe aus Kunststoff

The vertical centrifugal pump RVKu is specially designed for pumping aggressive, slightly contaminated media such as acids, alkalis and chemical waste water. The closed impeller design with long axial throttle gaps allows immersion depths of up to 3m at operating temperatures of 90°C. Smooth running of the shaft is ensured by the use of a ball joint bearing located outside the aggressive zone as well as an immersion plain bearing made of SIC, carbon or ceramic.
