Thank you for revision 3 of the general arrangement drawing. By this change the majority of the dead ends were eliminated. The remaining crevice, between the axle and the fixed seal part, is small. Although not fully complying with the EHEDG guideline it can be acceptable if there is a good reason to choose this construction. Rationale: the food safety risk for the intended use is negligible. Could you please check if a construction like fig 4.2 in Review seal design drawing 15-116-02-GA revision 2 is not possible at all and give the reason? For instance: the seal, already bought, cannot be used in a construction like fig. 4.2. For future projects (production machines) with AVEBE we have to pursue full compliance with the EHEDG guidelines which means further improvement of the seal construction. 
Please give your comments.
