Bosch In-Line Pumps

Hay maker2 · Apr 20, 2015

Educate me on the Bosch in-line pumps. The Bosch part numbers have a alpa-numacical sequence that clearly states what the pump is, can someone explaine to me what they mean? Is it safe to say that any of the pump from a 40 or 50 series or evan a combine will interchange? Maybe a few minor adjustments?
Thanks

PES6A95D410RS2522 for example, PES is flange mount, PE is base mount. 6 is # of cylinders, A is size, there's also M, MW, P, and Z. 95 means 9.5 millimeter plunger size. D is latest version with delivery valve holders with O rings and top sealed delivery valves 410 refers to supply pump and pump mount location, left or right. RS means clockwise cam rotation while LS is left hand. 2522 means 2000 series with heavier cam and bearings than 1000 models, both have adjustable tappets for internal phase timing. 3000 series has larger shim type tappets. Some combine pumps have a higher low idle speed, and governor regulation set quicker than tractors. For example, Gensets are 3% regulation, combines 5 to 7% and most tractors are 8 to 10%.
