Standardized chemical pump in plastic

Chemie-Pumpe RCNKu-plus
Horizontale Chemie-Pumpe aus Kunststoff
Horizontale Chemie-Normpumpe
Chemie-Normpumpe aus Kunststoff

Pumps of the RCNKu+ type family are horizontal, single-stage, end-suction, top-discharge centrifugal pumps, standardized to EN 22858 and ISO 5199. The pumps are used for handling chemically aggressive and/or inflammable liquids within the wide field of chemical processing and environmental technology. The RCNKu+ with closed impeller is foreseen for clean liquids and fluids with a small content of solids.  

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.
