Motor-driven Metering Pump Sigma/ 1 (Basic type)

The Sigma/ 1 Basic is an extremely robust motor-driven metering pump with patented multi-layer safety diaphragm for excellent process reliability. It offers a wide range of power end designs, such as three-phase or 1-phase AC motors, also for use in areas at risk from explosion.

• 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 overload and bleed option during the suction process ensures reliable operation.
