Speed rings vary according to the diameter of cylinder block to which they are attached. You may 

order them directly from the pump manufacturer or a Sauer-Danfoss Global Service Partner may 

retrofit them to existing pumps and motors (mounting requires some specialized tooling). Order 

them using numbers in the following table. Pump and motor listed is typical. Several may use the 

same speed ring.
