Correct. No individual internal part available, from either MB or OEM
(I thought sometimes it is Bosch but I may remember wrong). Anyway, I
tried too. Same MB part # on the pump assembly outside but different
internal design in the motor. Don't waste your time.
One of the pump I disassembled was made from graphite (like the lead in
2B pencil). That surprises me. I thought that is too soft to last but
maybe easy/cheap to make.
