Safe: In the event of an accident, the feed chemical does not escape to the outside nor into the pump's power end, thanks to the patented multi-layer safety diaphragm with optical (optionally electric) signalling.
Integrated relief valve protects the pump against overloading and reliable operation by means of a bleed option during the metering process.
External control is scalable via potential-free contacts with pulse step-up and step-down, batch mode or via a 0/4-20 mA standard signal.
Flexibly connectible: Connection to process management systems via integral PROFIBUS®, CANopen interface.
Integral log book saves up to 300 events and simplifies troubleshooting and analysis of the cause.
Application
All industrial applications, either as a stand-alone unit or integrated in a complete system
Volume-proportional addition of chemicals in water treatment, e.g. sodium-calcium hypochlorite for the disinfection of potable water
Neutralisation in waste water treatment
Pulse-controlled metering in the bottling of different volumes e.g. glycerin filling of manometers
With an integrated timer as a control unit for simple processes, e.g. biocide metering in cooling water
