VERDER Liquids has introduced the Verderflex Ds500, a metering and dosing pump which has been designed specifically to challenge traditional technological solutions to chemical dosing in municipal and industrial pumping applications.
The principle behind this technology is to improve accuracy and save the end user money by taking into consideration total cost of ownership, which includes upfront and lifetime operation costs. For the end user it is not just purchasing the pump but the working life and all it entails, i.e.: service, tool-free maintenance and chemical usage.
A key advantage of the Ds500 is that it has an easy ‘click and go’ cartridge change. The main wearing component, the peristaltic cartridge, can be changed in one minute equating to minimal maintenance time and spare part components. In combination with Remote Assistant (RA) IoT Monitoring, it adds real value. The Remote Assistant supports monitoring but does not allow control of the pump. It ensures accuracy in the process and provides alerts to any problems. Changes are predicted, so maintenance can be scheduled.
Performance is recorded and feedback provided. As a result, downtime is managed and minimised.
The Ds500 can deliver up to +/- 1% accuracy with a smoothed flow (i.e., reduced pulsation due to the design). Furthermore, this pump has an accurate flow performance from 0.1 up to 500 ml/min and pressures of up to 7 bar, resulting in greater accuracy and smoothed flow. It wastes less chemicals and saves on the life operation costs, supported with a 5000:1 turndown.
The unit, by virtue of being a peristaltic pump, can handle solids, abrasives, slurries, crystals and is not affected by ‘off gassing’ (i.e., such as sodium hypochlorite in the potable water industry). The Ds500 will deliver a reliable working life. It does so without the need for additional valves or complicated pipework required by other systems, and therefore has lower installation costs.
Tthe new Ds500 is available across Verder Group’s operational footprint, including in South Africa and Africa.
