The sealing is not included in the scope of delivery.
Hygienic design
| The wetted surfaces made of stainless steel are executed according to EHEDG Doc.8 and ASME BPE SF3 (Code: HY). |
| We guarantee the following surface roughness values: |
| Diaphragm foil: Ra ≤ 0.38 µm Laser welds: Ra ≤ 0.76 µm Turned parts: Ra ≤ 0.76 µm |
| Further versions of hygienic design upon request. |
System filling
