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.
