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 visual (optional electrical) signaling.
• Integrated relief valve to protect the pump against overload and 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 "left-hand liquid end" 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.
• Customized designs are available on request.
