The average well pump uses anywhere between 750 and 1,050 watts of power. The wattage will depend on the size of the pump's horsepower. For a median-sized home, the pump will generally consume 1/3 horsepower, meaning 800 watts. The starting power requires two times the wattage it needs for running.

One way or the other, how do I know what size well pump I need?
The key to sizing a submersible well pump is to calculate the gallons per minute of water required during peak periods. Smith recommends sizing a submersible well pump based on fixture count, which involves counting the fixtures and faucets in a home.
Thus, how do I know what HP water pump to get? The following formula can be used to calculate water horsepower (WHP).WHP = HQ / 3960.Where H is the change in pressure measured in height of water in feet and Q is the water flow rate in gallons per minute. ... WHP = (112 x 460) / 3960 = 13.0.
Equal, what is the difference between 1/2 hp and 3/4 hp water pump?
The ½-horsepower model can pump up to 8 gallons per minute, while the ¾-horsepower model can move 12 gallons per minute; its 1-horsepower model can pump up 18 gallons per minute. The ½-horsepower motor runs off a 115-volt power source, while the ¾- and 1-horsepower models require a 230-volt power source.

Stainless Steel Submersible Well Pump The 1.5hp Submersible Deep Well Water pump gives you a class-leading flow rate, producing a consistent flow rate at up to dizzying 380 ft depth under surface.
For example if an 0.5 HP motor with discharge rate of 200 litres per hour takes 2 hours to lift the water, then an 1 HP pump with higher discharge rate 400 litres per hour can complete the task in less than 1 hour.
For each 1.5 inch intake line, the maximum flow into the pump will be 42 gallons per minute (GPM).
It is 95 feet down and pumps a consistent 11 gallons per minute at 40 psi, which is more than adequate for my needs. Unless you are completely knowledgeable about submersible pump installation, I strongly recommend professional installation.
The higher it is, the quicker it pumps. A range of 100-200 LPM is usually sufficient for a household. Head Range – Head here refers to the discharge head – the vertical distance that you will be pumping the water. The head range should fall within this distance for the water pump to pump water effectively.

The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).

For a 1/2 HP submersible pump, a 15 amp 2 pole breaker would be normal. You can run 12 AWG, but unless the run is very long, 14 AWG is sufficient. Bigger wire would let you switch to a bigger pump later if you wanted.
5000 watt is plenty to run the well, a furnace, refrigerator, some lights, small tv, and even make coffee.. I have a 4400 watt gen. and do all that with no problems at all.. Well pumps have a a very high start up current.
Central furnaces typically use less than 1,000 watts, but large air conditioning units can easily run over 2,000 watts. In addition, remember that you may need to run a well pump or sump pump. ... So, 3,500 watts is perfect for home use if you only need to run relatively small appliances around your kitchen.

A 1/2 Hp pump should be able to push water up hill 40 ft without problems. The distance it pumps is somewhat irrelevant. The more important question is how deep the well is. If the well is shallow then a pump is able to suck water up the well pipe.
When choosing a motor for a centrifugal pump, you must consider the impeller size, maximum capacity, specific gravity of the fluid, and service application in case API requirements apply. If you take these things into account, you will select the right motor for your centrifugal pump application.
Pumps are rated in GPM (gallons per minute). A typical 3- to 4-bedroom home requires 8-12 GPM. When determining your home water needs, add one GPM for every water fixture in your home.
