ProMinent® Sigma/1 Motor Driven Metering Pump

The Sigma/ 1 diaphragm metering pump together with the Sigma/ 2  and Sigma/ 3  represent an integrated product range. They cover the capacity range from 17 to 1,040 l/h. The entire Sigma Control product range is equipped with intelligent features to provide a high level of operating convenience, safety and efficiency. The pump features a removable operating unit and adjustable metering profiles to ensure optimum metering results.

Excellent process safety and reliability:
  • In the event of an accident, the feed chemical does not escape to the outside or into the pump's power end, thanks to the patented multi-layer safety diaphragm with optical (optionally electric) signalling
  • Integrated overload shut-down in the pump control to protect the pump from overloading and thus significantly reduced pressure surges caused by blockages.
  • Integrated relief valve protects the pump against overloading and bleed option during the suction process ensures reliable operation
  • Metering accuracy is better than ┬▒ 2% with a 30-100% stroke length adjustment range under certain defined conditions and with proper installation.

Flexible adaptation to the process (control range)

  • Detachable operating unit with large illuminated LC display for outstanding user convenience
  • Metering profiles for optimum metering results
