From context, I got that it's a pump. That's sufficient unless I have to actually deal with such a system....

Of course, mholland's comments indicate it's a pump at the top of a well, not at the bottom.

Ok, you got me curious, so I looked. This is a pumpjack:

One for a water well will be a lot smaller. They are mostly thought obsolete for water wells, but they do require only a small motor, and you can work them manually if you have to.

It's a pump jack, Jody Mack,
Used since Teapot Dome,
M'holland's ma's got one at home.

A pump jack is a device to convert rotary motion to a vertical reciprocating motion to operate a submersible piston-&-valve pump from the surface, commonly used to lift water and also liquid crude petroleum from underground sources.

I have a certain fondness for the old-style flywheel engines that powered oilfield pumpjacks for decades, self-powered from the flammable gaseous "top" of the pumped petroleum. I saw too many to count crossing the country on I-70 in the 60's and 70s, then a few dozen, then the last crossing mebbe 2 still running, all given over to maintenance-free electrical power now widely distributed.

Oh God those old one cylinder gas engines, they came in all sizes. The lumber yard across the river had a big one that could be heard all over. Every once in a while it would fail to fire and you would hear bump, bump, bump, nothing, bump. You never saw so many rotating shafts and belts as that single engine ran every tool in the building. With that big flywheel nothing would stop it.

DesJardains was a major mfgr of those large flywheel horizontal engines in Canada decades ago, AFAIK they may still be in biz. Down here Fairbanks Morse tended to be the 800lb gorilla tho' there were literally hundreds of makes at one time, the engine in the pic may be an Ajax.
Met a guy in rural SLC several years back that had one of these monsters under cover in the back that drove a generator to charge a set of lead/acid batteries for his dual-wired house.

My oldest brother, rest his soul, had a walk behind tractor powered by one of those, quite a machine. How things change, I have an 18 HP tractor that is all hydraulic even the steering.
