How to interpret our model key?

The model codes that we use to identify our instruments can be found in the brochures of our various product series. In a few cases it may happen that the codes used are not listed there. From 2018 we have introduced a number of new codes for couplings and seals that are not used so frequently. For this reason you will find the complete, current coding for these items in the tables below.

Note: 9 (numerical) and Z (alphanumerical) are used in our model key to indicate non-standard options (not listed in below tables). Details about these non-standard options are specified on our order acknowledgement.
