emergency operation

Reliable emergency operation even in case of diaphragm rupture

Compared to other diaphragm systems in the low pressure range the LEWA safety diaphragm has two working diaphragms already! This alone provides double safety. If the first working diaphragm is worn the second working diaphragm takes over its work.

If the second working diaphragm is worn also this is immediately and reliably indicated by the monitoring diaphragm and the standard diaphragm monitoring system.

However interruption of the production process is not necessary! An also pressure stiff safety diaphragm takes over the task of the working diaphragms! The production process can be continued up to the next scheduled stop and the LEWA ecodos still remains hermetically tight!
