RVKu

Chemical centrifugal pump in plastic

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.

The pump is equipped with the i-ALERT®2 sensor as standard. This monitors vibrations and temperature. If preset limit values are exceeded, LEDs in the sensor light up. All measured values can be retrieved via an app or the Ai Platform. This means that necessary measures can be taken in good time before the pump fails.
