If an old bearing was being refurbished I'd wash it with parafin or similar to flush out all the crap and give me a clean bearing to visually inspect. Then repack by hand.

Indespension do bearing savers ..They are a stainless steel cup that fits over the bearing. Within the cup is a grease resevoir with a grease niple facing outward. Fit the bearing saver, pump full of waterproof grease and the internal spring mechanism will keep the bearing greased. Works very well for me so far.
Let me know if you want a photo.

Its a trailer I have just had made for my sib . Only little 8" wheels very light . Made by Dutchy trailers .
The guy sells trailers on ebay by the Name of Garydutchy . Iam very pleased with it , he made it to my drawing all galvanised for £375 in under 2 weeks .
Here is his Number maybe the hubs are available for other trailers . 07968321097.
Surely it would be easy enough to drill and tap grease nipples into your existing hubs ?

several different types of this simple idea. Some are nothing more than a spring loaded pressure plate that keeps a bit of pressure on the grease reservoir; some have a ring to show how full the reservoir is. Sold under the names Bearing Buddy, Buddy Bearing, Bearing Saver, bearing protectors, and probably a host of other names.
There is also a system that has the spring located at the back; filling with new grease routes the grease through the outer bearing, then the inner bearing, and back out to a port at the end of the axle (Dexter EZ-Lube.)
Last, there are oil-bath hubs; These replace the greased bearings with oiled bearings; the system keeps a quantity of oil (usually about half full) in the bearing chamber so that on each revolution of the bearings, the thing rides through the oil bath.
Probably a few other types that I'm forgetting as well.

edit: pics are in the wrong order: Standard is 3. Indicating is 1. Turbo Lube pics are self-explanatory.
I've got something similar to that on my trailer (in truth, I have no clue what it looks like, as it came from my builder that way.) This is for flushing the brakes, not so much to protect the hubs.
Basically some plumbing to get water from a hose connection on the frame to each of the brake drums. There, there's some kind of spray head thingie which is attached thru the backing plate, and that saturates everything inside. Mine is a brass hose connector (female), a bunch of clear plastic tubing, and the aforementioned and unseen spray heads. All held on with zip ties.
No idea whether it does any good or not, but since its there, I use it after every trip.
I would bet that you could kludge together something from stuff from the hardware store/garden center for a hell of a lot less than 70 pounds, though.
