Metering pump Sigma/ 3 (Basic Type)

for chemicalswith electric motordiaphragm

The patented multi-layer safety diaphragm for excellent process reliability is just one feature of the extremely robust motor-driven metering pump Sigma/3 Basic. It also offers a wide range of power end versions, such as three-phase or 1-phase AC motors, also for use in ATEX areas. The robust pump for safe and reliable use The Sigma/ 3 diaphragm metering pump together with pumps of type Sigma/ 1 and Sigma/ 2 represent an integrated product range. They cover the capacity range from 17 to 1,030 l/h, with a consistent operating concept, control concept and spare parts management. A wide range of power end versions is available, including some for use in areas at risk from explosion. Your benefits Excellent process reliability: 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 Integrated relief valve protects the pump against overloading Reliable operation by bleed option during the suction process Flexible adaptation to the process: The entire Sigma product range is available as standard in a "Physiologically safe in respect of wetted materials" design. Metering pumps with electro-polished stainless steel metering head enable them to be used in hygienically challenging applications Wide range of power end versions, also for use in areas at risk from explosion, and different flange designs for the use of customised motors
