There are two types of water pumps, submersible and fixed position. Each pump is wired differently from one another.
Use the discussion page to state what type of pump you are talking about.
The amount of amperage needed for a 220V well will depend on the wattage of the well pump. To calculate the amperage, divide the wattage of the pump by the voltage (220V) to get the amperage required.
No, the neutral wire is not needed for a 220V setup as it is a single-phase system. The two hot leads will supply the necessary power for the motor, while the ground wire is for safety grounding purposes. Always refer to the motor's specifications and local electrical codes when making such conversions.
The amperage a 220 volt well pump will pull depends on the wattage of the pump. You can calculate it by dividing the wattage by the voltage (220V) to get the amperage. For example, a 1 HP well pump typically pulls around 8-10 amps at 220 volts.
The contraction phase of the cardiac cycle is called systole. This is when the heart muscle contracts to pump blood out of the heart and into the circulatory system.
It sounds like you have a three phase motor that you are trying to put in where you have a single phase 120volt motor. You can purchase a three phase inverter, but the cost will exceed the cost of the new motor sized for the right wiring and voltage.

Assuming that your pump start relay is a contactor with overload protection and a 220 volt coil. Connect the incoming 220V to the connection points on the top of the contactor. Connect the pump motor to the bottom contactor connection points. From the right incoming voltage connection point take a # 14 wire, in flexable conduit, to one of the N.C. (normally closed) terminals in the pressure switch. The pressure switch which should be connected into the water line at this time on the pressure side of the pump. From the opposite N.C. terminal in the pressure switch take another # 14 wire, in the same flexable conduit, to one side of 220V contactor coil. At this point, (1) if overload contacts are available, take a # 14 wire from the other side of the 220V contactor coil to one side of the N.C. contacts in the overload block. From the opposite side of the N.C. contact in the overload block take a # 14 wire up to the left side of the incoming 220V connection point. If there is no overload block, as some motors have internal overload protection, (2) take a # 14 wire from the other side of the 220V contactor coil directly to the left side of the incoming 220V connection point. As you can see the circuit is all series connections from voltage supply to pressure switch, to overloads, to return voltage supply. With the pressure switch contacts closed and the overload contacts NOT tripped the pump will start. When pressure reaches the set point the switch will open and the pump will shut off.
No, as long as the generator has sufficient KW for the pump's requirements. A 3/4 hp, 220V motor draws around 5 to 6 amps. That's 1.1 to 1.3 KW, but because motors have high starting current, your generator should be rated for at least twice that, preferably 3 times. I would recommend a 3.6KW 220V generator to be safe.
Downstream of the pump.
No, the neutral wire is not needed for a 220V setup as it is a single-phase system. The two hot leads will supply the necessary power for the motor, while the ground wire is for safety grounding purposes.

It depends on what kind of car and engine you have. Some don't connect to the water pump but to the radiator.
what is the type of pump three phase or single phase
You will have to get that from the dealer.
A lymphedema pump is used to remove excess fluid from an injured or affected limb. The pump returns the fluid to the cardiovascular system. Treatment is done in two phases: the preparatory phase, or manual drainage and the drainage phase, which the pump is used for.
Not usually, if the three phase pump is a three wire pump then the disconnect does not need a neutral. The pump control may or may not need a neutral depending on the voltage system that the control panel needs.
