Well Pump Power Consumption

A deep well pump typically uses 250 to 1 100 watts of power.

Well pump power consumption.

The power consumption for pumping water can be expressed in metric units as. Pumps and air conditioners. P h kw 1 m 3 h 1000 kg m 3 9 81 m s 2 10 m 3 6 10 6 0 027 kw. A typical water pump s wattage can vary between 250 watts to 1 100 watts.

Power consumption in metric units. This maxes out my 5500w generator at startup. P q h ρ 6116 10 3 μ 3 where. P power kw q flow liter min h head m ρ density kg m 3 water 1000 kg m 3 μ pump efficiency decimal value example power required to pump water.

The shaft power the power required transferred from the motor to the shaft of the pump depends on the efficiency of the pump and can be calculated as. If you have a 100 ft deep well and if you want to pressurize your water to a bare minimum of 30 psi ie another 69 ft of lifting each gallon of water you pump will require almost exactly 1 watt hour of power assuming the 55 efficiency. Big water pump station figure 3 projected average day power usage 2011 projected average day flow 0 200 400 600 800 1000 1200 1400 1600 1800 january february march april may june july august september october november december month average power kw 5 10 15 20 25 30 average power consumption current condition pumps 877 kw after. Pumpingenergy ep x 8760 equation 30.

For modeling best available pump motor systems we assume a combined efficiency of 0 60. Then multiply it by how many days a year it runs and divide by 1000. Finally we calculate annual energy consumption for well pumping using the following equation. Take the wattage of the specific water pump and multiply it times how many hours a day it runs.

The most common types of pumps are jet pumps and submersible pumps. I wouldn t recommend anything smaller than a 5kw generator for.
