Kit numbers on this page are taken from the Danfoss and Sauer-Danfoss quick reference parts manuals 520L0910 (variable pumps), 520L0911 (fixed motors) and 520L0912 (variable motors) for the Series 20 through 27 family, and from the Sauer overhaul kit quick reference for the Series 15, 18, 40, 42, 45, 51 and 90 families. A kit fits a frame size and a unit type, not a machine, so the model code from the nameplate is what decides it.

Which seal material do you need?

Sundstrand built to Buna-N and never cataloged an alternative material. Its part numbers also turn on the date code, so send that from the nameplate with any request.

Choosing the wrong material is the most common cause of a repeat failure, because the right choice is set by the fluid in the system rather than by the pump.
