Precise dosing, easy control, minimal downtime
The Verder Verderflex Ds500 utilizes precise peristaltic technology, offering significant advantages over traditional systems by removing the need for complex pipework or valves. This design not only improves accuracy, leading to less chemical usage and direct cost savings, but also excels with difficult media like abrasives and slurries. Furthermore, the pump minimizes whole-life costs through its "click and go" cartridge change—the only wearing component—and leverages Remote Assistant (RA) for IoT monitoring, actively managing and minimizing downtime.
Designed for versatile and reliable precision, the Verderflex Ds500 is the solution for a broad spectrum of challenging fluid metering and transfer applications, including:
- Metering & dosing
- Disinfectants
- Pigments
- Acids/Alkalies
- Cleaning agents
- Sampling
- Flocculants
- Additives
Technical features
