The Sigma 1 is an extremely robust motor-driven metering pump with a patented multi-layer safety diaphragm for outstanding process reliability. It has a capacity range of 17 to 1,030 liters/hour and is available in a variety of power-end versions, some of which are used in explosion-endangered areas.
Functions and advantages
1.In the event of an accident, the feed chemical does not escape to the outside nor into the pump's power end, thanks to the patented multi-layer safety diaphragm with optical (optionally electric) signalling. 2.Integrated relief valve to protect the pump from overloading. 3.Reliable operation by bleed option during the suction process.
