## How much kWh does a water pump use?

Well pumps should be sized by a professional. It is not uncommon for people to have 3/4 hp pumps installed in their wells equaling 30 minutes of pumping per day or 350 kWh/yr, while a ½ hp pump, which uses only **240 kWh/yr**, would be sufficient.

## How much power does a water pump draw?

A water pump’s wattage can range from **250 to 1,100 watt**. Take the wattage of the water pump and divide it by the number of hours it runs. Divide by 1000 the number of days it runs. The amount of kilowatt-hours the pump is using will be given by this.

## How much power does a 1 kW motor use?

If the motor is fully loaded, it will provide output power of 1 HP = (1 X 0.746) kW = **0.746kW**. Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW.

## How much do water pumps cost to run?

The average cost is **$0.12 per Kilowatt hour**. You will then multiply the three (power consumption, operating hours, cost of electricity) together to calculate total cost per month.

## Does a water pump use a lot of electricity?

A typical water pump’s wattage can vary between 250 watts **to** 1,100 watts. Take the wattage of the specific water pump and multiply it times how many hours a day it runs. Then, multiply it by how many days a year it runs, and divide by 1000. This will give the amount of kilowatt-hours the pump is using.

## Do water pumps consume a lot of electricity?

Pumps draw power every time you turn on a tap. The **energy consumption of pumps increases as the pumps get more powerful**. For example, pumps rated at about 35L a minute use about 600 watts when they are pumping, while pumps rated at 45L a minute can consume about 800 watts.

## How much energy does a 1 hp pump use?

Our 1 hp example pump uses **1.75 Kw per hour**; whereas a 2 hp motor of the same type (UST1202) would draw 2.4 Kw per hour. That’s around 24 kWh per day, or around 720 kWh per month, just running only 10 hors per day.

## How much power does a 12v water pump use?

A water pump when used when running will pull about 5 Amps at 12 volts or **about 60 watts**. The good news, is that the water pump usually only runs for a few minutes at most. Thus it is a relatively small load.

## How much power does a 1hp well pump use?

Different Sizes of Well Pumps and Wattages

Size of Pump Motor | Running Wattage | Starting Wattage |
---|---|---|

1 HP | 2,000 to 2,400 |
4,000 to 7,200 |

1.5 HP | 2,500 to 2,800 | 5,000 to 8,400 |

2 HP | 3,750 to 4,000 | 7,500 to 12,000 |

3 HP | 5,000 to 5,500 | 10,000 to 16,500 |

## How many kW is a 5hp motor?

Three Phase Motors

MOTOR RATING | HP | APPROX. F.L.C. AT LINE VOLTAGE |
---|---|---|

3.7 kW |
5 | 15 |

4.0 kW | 5.5 | 16 |

5.5 kW | 7.5 | 20 |

7.5 kW | 10 | 27 |

## How much power does a 100 hp motor use?

Data Logger information imported into a spreadsheet for analysis. This 100-horsepower centrifugal pump motor, if fully loaded, should be consuming nearly **80,000 watts (80 kW)**.

## How much power does a motor consume?

Calculate the power the motor consumes while in operation. The equation is **W = AV(sqrt 3)** where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts.
