Sundyne Gearbox Lube Oil Pump Expected Life
Sundyne Gearbox Lube Oil Pump Expected Life
(OP)
I'm looking to get a better sense of the life of the internal gearbox lube oil pumps on high speed Sundynes. The local salesman stated that I should expect ~2 years which seems very low to me. I'm not sure if this is their conservative answer to cover any issues one may have or if this part should be considered a standard wear item that needs to be replaced frequently.
I'd like to hear from actual users on the MTBF (mean time between failure) of the internal lube oil pump on Sundyne high speed gearboxes (and any other thoughts you have regarding this matter).
Thanks in advance,

You might simply take up the question with the manufacturer of the lube oil pumps to see what they advise a reasonable life is, and what a sensible maintenance strategy might be.

For other gearboxes, as described by geesamand, I agreed that shaft driven oil pumps are generally a bad idea. But, even with these I would expect 10+ years from the pump. The weak link tends to be the drive coupling. These are often coupled to the end of the bull-gear with a very crude tab-and-socket, steel-on-steel coupling. These need to be inspected at least once every four years for continuous service. Once again, the reliability of the pump depends on proper priming, good oil condition and good filtration

Location of the equipment will play a big role in how it gets maintained. With the proper maintenance they should last a while but as M&O practices vary between companies and regions of the world drastic differences in lube oil pump life will be observed.
Exactly what I was looking for, thanks!
