220 wiring question for my well

my sons well is a 220 volt above ground pump, there are (in the pressure switch) 2 spots for the live wires and a ground. there is a cord mad up of regular 2 wire with a black and white (and ground) wired to a 220 volt cross slotted plug. at the receptacle the feed wire is 3 wire (red, black, white and ground) but the white wire is just capped off with a mar. Is this proper or should this be a 4 wire receptacle and the white wire carried to the pump's pressure switch and be bonded some where?

No need to carry the neutral to the pump if it is 240 only. It's fine the way it is.

The neutral is necessary in case you decide to cover the well and need a 120 volt supply to power a heat strip or other lower voltage item. Having it capped off is fine until such use is required.
