Seals (O-ring, oil seal, back-up ring)

Same position, every family - full table

One row per drawing position in this category, one column per pump family. This is where you can see at a glance whether a number carries across families or changes with the family and the control variant (DT / DTP / DTH / SH). A dash means the catalogue does not list that position for that family, and every number is a link to its own page.

Reading the table: a position that is filled in every column is a part that is common to the whole range; a position with one filled column belongs to that family only. If your number does not appear here, send it to us - the catalogue line it belongs to is what decides, not the position alone.
