Would it be possible to run my lubrication system[10W motor continously run] and the coolant[motor about 5inch diam by 4inches long[no plate]] pump, from one vfd? I am guessing the coolant motor is around a 1/4hp.

Do you intend to use it permanently set for 50hz?
If so, you most likely should have no problems, especially for those small a motor.
The only thing I can see is they may have to be the same pole count, 2 or 4, for setting up the parameters.

Seems the answer is get a vfd and see.

I have used two identical motors on a VFD and variable speed/Hz, but not ones that were different size so it may be a case of each application being different and may well be a case of try and see.

I would be switching from the oil pump to having both pumps running.
