Without knowing the exact amperage and voltage and phase it is hard to say. Many motors have different characteristics depending on their applications even though the horse power remains the same. A rule of thumb used is 746 watts = 1 horsepower, this is a general figure.
1000 watts
About 3/4kW
It would depend on how deep your well is, and how efficient the pump.
19.a heat pump has a COP rating of 2.5 to 1. If 200 watts of electricity are used to run the heat pump, how many equivalent watts(heat) are produced?
1 horsepower = 745.699872 watts So a 1/2hp pump would use 372.8497936 watts
Probably 100-200 watts but only when the pump motor is running.
Take Amps times the volts to get Watts 115x15= 1725 120x15=1800 or 125x15=1875 (These are different voltages found in houses) i would go with the max of 125 volts and 1875 Watts so go for a 2000 watt (2kW) generator.
Voltage of the pump (12) multiplied by the current draw = the watts used. This would be 12 watts if the current was 1 amp, 24 watts if the current is 2 amps, and 36 watts if the current is 3 amps, and so on...

It is NOT electric!
Increasing the watts, but the hire the watts the more u pay for ur electric bill. so 120vac will have to be 208vac to increase the wattage.
1 horsepower = 745.699872 watts So a 1/2hp pump would use 372.8497936 watts
at least 1500 watts, 1horse power is 746 watts, therefore 1/2 horsepower is 373 watts. But the answer will depend on the %age efficiency of the motor in the pump. Assuming an efficiency of 50% 746 watts would be an appropriate answer.
the impeller of the pump, discharges the water of a steam or air or electric driven pumps.
You can approximate the horsepower capabilities of any electric motor by calculating incoming electric power. This is done by simply multiplying the rated voltage by the rated current. This will give you a unit of watts. There are about 746 watts per horsepower. Say if the motor is about 85% efficient, then incoming power will match output power minus this efficiency. Anyways, multiply incoming power by .85 and divide by 746 should give an approximate horsepower of the water pump's motor.
Probably 100-200 watts but only when the pump motor is running.
An electric air pump oxygenates the water in an aquarium, this allows the fish in the fish tank to breath. if there was no air pump the water would lose its oxygen and the fish would drown.
The big issue isn't an electric water pump, but the fact that you have to replace the pulleys. If you can pull that off you should be good to go, even with a belt-driven water pump.
