This probably ins’t an “NEC” issue so much as a “listing” issue. I will outline some of the things a testing lab would consider, were such a thing submitted for evaluation.
First of all, cords have to be attached in such a manner that both protects the conductors from abrasion, and which relieves any strain- without that strain being transmitted to the electrical connections.
With that in mind, the connection of the UF to the pump with the two-screw connector may not be adequate; the connector should be one approved for UF.
In a similar manneer, the orange cord needs a proper connection to the housing. Since this part is more likely to be subjected to pulls and tugs, a better connector would likely be required- such as one of those with the rubber bushings in them. Passint unprotected conductors through a seam in the metalwork is not acceptable.
The size of the wiring chamber would be considered...is there enought room for the wires? I doubt this box has enough room.
Finally, there is the matter of over-current protection. If the pump is, say, a 220v 30A, with the "receptacles" tapped from the feed.....well, this would not be allowed.
If I had to describe this installation, I would note that the pump appears to have been modified in a manner inconsistant with its' listing, and seems to violate several generally accepted wiring practices.
I might also note that work such as this suggests that work was performed by an untrained person- and that a closer inspection of work performed by this person is warranted.
