The Robust Pump for Safe and Reliable Use
The Sigma/ 1 diaphragm metering pump, together with pumps of type Sigma/ 2 and Sigma/ 3, represents 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 overload and bleed option during the suction process ensures reliable operation.
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.
- Adaptation to specific installation situations, as the ‘Liquid end on left’ option can be selected as standard.
- Wide range of power end versions, also for use in ATEX areas and different flange designs for the use of customised motors.
