This is a voltage drop question. To answer this question the voltage of the pump must be stated
That can't be answered until you state the voltage.
From the question it is hard to establish whether the service size is 350 amps or the service conductors are 350 MCM in parallel. If the service is 350 amps, the grounding conductor is #3 bare copper wire. Parallel 350 MCM conductors will allow for a 600 amp service. The grounding conductor for a 600 amp service is a #1 bare copper wire.

Nope. 350 meters is less than 1,214 feet. (350 meters = 1,148.29 feet).
That depends on the load. In other words how many amps does your load utilize or how many watts? Either figure will work. <<>> Wire size is based on amperage. The higher the load amperage the larger the wire size has to be. In this case also, the wire has to be increased in size to over come the voltage drop for the distance to the load. To receive an answer restate the question with the load amperage or wattage.

i would use a pump that pushes at least 350 gallons an hour
About $350 depending on the size

7/16-14
2 1/2" EPVC schedule 40
A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.
to answer this we need to know what size engine and whether diesel or gas engine

buy a window, thru the wall, or portable unit. you can size it wherever you buy it. they will have a chart of some sort to size it for you.
350 kilometers = 1,148,293.96 feet.
350 metres = 1,148.3 feet
