10184
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.
