Your benefits

High process reliability:

• In the event of an accident, the feed chemical does not escape to the outside or into the pump drive, thanks to the patented multi-layer safety diaphragm with optical (optional electrical) signaling
• Integrated relief valve to protect the pump against overload
• Reliable function thanks to venting option during the suction process

Flexible adaptation to the process:

• Variants with EU 1935/2004, FDA or Hygienic Design can be selected for food applications.
• Adaptation to special installation situations, as "liquid end left" can be selected as standard.
• Wide selection of drive variants, also for the ATEX range, and various flange designs for the use of customer-specific motors.
