Adressing all dosing system challenges

With a SMART Digital diaphragm dosing pump, you do not need to install third-party bleed valves or manually vent your system when dosing sodium hypochlorite or other degassing chemicals; the pump’s automatic degassing features handle this for you. With a SMART Digital pump, you don’t need to purchase expensive external flow meters; the pump can measure the dosing flow. If a valve is clogged somewhere, or the flow is too high, the pump detects this and notifies you. And it can do so in more than 28 languages on the easy-to-read user interface.

Chemical dosing poses many challenges, but the SMART Digital range has been designed to solve them so you can reach your performance targets. The pump range handles flow rates up to 200 litres per hour and output pressure ratings up to 16 bar. No matter if you handle wastewater treatment at a municipal wastewater plant or add coagulants in complex industrial manufacturing processes, you need maximum uptime and minimal operating costs, and you need process safety, especially with hazardous chemicals. The SMART Digital range can help you achieve all of this, and more.

Key benefits:

  • Accuracy: Industry-leading accuracy confirmed by independent study
  • Durability: Diaphragm resistant to virtually all chemicals; pump housing IP65/NEMA4X certified
  • Reliability: Industry-leading service intervals
  • No vapour lock: Deaeration features enable continuous dosing of degassing chemicals
