How many watts does a water pump consume - ERNIEGRAVES | Process measurement and control (2023)

Energy consumption of water pumps

Water pumps consume energy like any other device. When considering the purchase of a well water system, there are several components to consider. Additional costs to consider are those incurred for operating the various components (eg the water pump).


A water pump is a mechanical device that mechanically pushes water from the bottom of a well into a storage tank within the structure, from where it distributes the water. Although it does not run continuously, the water pump consumes electricity when it is turned on and off.


The energy consumption of a water pump can be determined using a mathematical formula. The power of a standard water pump can be between 250 and 1100 watts, depending on the model. Take the wattage of each water pump and multiply it by the number of hours a day it runs. Then add the number of days in a year that it's running and divide by 1,000 to get the number of kilowatt hours the pump is using at any given time.


You can calculate the dollar amount each year by multiplying the kilowatt hour by the local cost of electricity, which in the example above is typically 8.5 cents per kilowatt hour. Note that a higher horsepower (0.5 to 5 hp) will require more horsepower to operate due to its variable horsepower.

How much electricity does a water pump use?

Asked in the following category: General Last updated Feb 18, 2020. The power consumption of a typical water pump can range from 250 watts to 1100 watts. Take the wattage of each water pump and multiply it by the number of hours a day it runs. Then add the number of days in a year that it's running and divide by 1,000 to get the number of kilowatt hours the pump is using at any given time. As per industry standards, a typical water pump can range from 250 to 1100 watts of output power.

Second, how is the power consumption of the pump calculated?

  1. Locate and record the pump's voltage and amperage. Detailed engine specifications must be printed on the engine tag. Multiply the voltage rating by the current rating to get the current rating. Calculate kilowatts (kW) by multiplying the total watts by 1000. Multiply the number of hours per day the pool pump runs by the kW. Multiply the kilowatt hour per day by the cost per kilowatt hour

With that in mind, how much electricity does a horse pump use? For electrical devices, one unit equals one kilowatt-hour, which means that one kilowatt of electricity is used for one hour. In this case, we have a one-horsepower engine. One horsepower (Horsepower) for 24 hours equals 74624 = 17904 watt-hours, which equals 17904/1000 = 17,904 power units. What is the power consumption of a fountain pump?

How much electricity does my submersible well pump use? — Oakville Pump Service

Over the last few months, a number of our customers and blog readers have expressed an interest in finding alternative methods to keep their well pumping equipment running during power outages. Our blog post on sizing generators got a lot of traffic from search engines; However, in this article, we've only covered the basics of knowing what size pump you have. What if you don't know what size pump you have and therefore can't choose the right generator? In this article, we go into detail to help you determine how much power your pump has, how much current/amps it is drawing, and how many watts of power it is using while running.

  • This label provides information such as the number of horsepower or kilowatts the motor is rated for, the number of amps the motor must draw, and the voltage the pump requires for effective operation.
  • But what about a submersible pump?
  • Submersible pumps are usually equipped with a distribution box to which the cables from the well are connected.
  • It may be necessary to remove the cover with a screwdriver to see the label on the inside of the control box.

If your submersible well pump does not use a control box pressure switch and instead uses a constant pressure or variable frequency drive to provide the information, read our latest blog which covers generator sizing for home pumping systems with VFD controls in more detail. 🇧🇷

(Video) Measuring well pump startup surge amp draw an amp clamp.

  • Call the man who installed the submersible pump if you know who he is!
  • Pay attention to this information and keep it safe!
  • If you don't know who installed the well pump and you don't have previous invoices or documents, look for the specific circuit breaker for the well pump.
  • What ampere range does the breaker display information on?

Please note that these suggestions are for classic pump kits that include a pressure switch/control box and a large pressure vessel.

A general summary of breaker sizes and alternator sizes for various 230 volt pumps is as follows:

A 15 Amp circuit breaker will indicate that the pump has less than 5 HP and will draw approximately 5 Amps/700 watts while running, requiring the use of an internally controlled generator of at least 1.2 KW to start and run the pump. A 20 amp circuit breaker indicates that the pump has less than 0.75 hp and is drawing 8 amps/1100 watts while running, requiring the use of an internally controlled 2 kW alternator to start and stop pump operation. One-horsepower pumps may run occasionally from a 20-amp breaker, depending on the installer and the amount of wiring available.

  • A 1 HP submersible well pump requires the use of an internally controlled 2.5 KW alternator to power the pump.
  • It is also used for 1.5HP pumps that require an internally controlled 3KW alternator to function properly.
  • A 50 A circuit breaker indicates that the pump has less than 5 HP and draws approximately 25 A/5300 watts while running, requiring the use of an internally controlled 7.5 kW alternator to ensure optimal pump operation.
  • This is not a typo or spelling error!
  • Once the pump has finished accelerating to full speed, current and power consumption will return to normal levels.
  • See page 5 of the AIM manual for more information or visit our blog for more information on sizing a generator for your submersible well pump.
  • What is the reason for the difference?
  • The pump may be capable of producing 1hp/946 watts of usable water flow/pressure, but the actual amount of power needed to do so is slightly higher due to design inefficiencies.
  • Imagine the following situation: you cannot identify the circuit breaker on your pump, you cannot locate the label or it is illegible and you have no documentation on the pump.
  • If that's the case, you might want to have a professional come in and do some simple electrical tests for you, such as: B. the winding resistance and the pump's actual operating current (amperage rating).

A professional in our field will charge around $200 to travel to your home, take the readings, and do some additional checks on your water pressure tank and pressure switch. He then gives you an idea of ​​what's going on and recommendations on anything unusual.

Here are some ideas to get you started.

After that, turn off the power to your pump and open Table 13 of the Franklin AIM manual for the necessary reference tables (also shown at the end of this blog). Locate the power line that connects to the submersible well of the pump; It should have four colored wires which are as follows: red, yellow, black and green.

  • Make sure your hands are away from power cords or devices before turning on the device!
  • If your submersible pump only runs on three wires and there is no control box, you can simply measure the amperage being drawn by one of the non-green wires and compare the value to the appropriate chart in the Franklin manual for two-wire motors. 🇧🇷 🇧🇷 (see Figure 1).
  • Be sure to turn off the power and replace all electrical covers before starting, then turn the power back on when finished.
  • Then turn on the T6-600 and set it to the omega signal (for ohms resistance measurements), connect the red/black leads from the tester to the black and yellow leads going to the pump and record the result.
  • Now connect the tester's red/black wires to the red and yellow wires connected to the pump and write down the result on a piece of paper.
  • Examine the resistance measurements and compare them to the values ​​listed in Table 13 in the Franklin AIM manual.
  • You should be able to identify the exact pump size in your well.
  • Be sure to reconnect the wires where they originally were and turn the power back on or you'll run out of water.
  • When it comes to keeping water flowing for businesses, homes and farms, our skilled Oakville Pump Service employees help customers in Napa, Calistoga, Pope Valley and everywhere in between.

An A1 high pressure pump MUST consume about 750 watts when running and about 15-1800 watts when starting. Can a 5000 watt generator power a well pump? Homeowners typically use most appliances between 3,000 and 6,500 watts. If your home has a modest oven and tap water, you can assume that 3000-5000 watts is enough to meet your needs.

Can my generator power my deep well water pump?

If you already have the generator, I encourage you to use it and give it a try. If the alternator is of any quality it will regulate the voltage more than is reasonable for an engine and ensure that the engine is not overloaded by alternator voltage. Even if the generator cannot handle the load, it will not damage the engine unless forced to stop continuously for a long period of time. Don't damage the generator, it's like trying to use a dead battery; If the battery doesn't generate enough power, it simply won't work.

Generators (including those used by power plants) provide electricity on demand; a home generator produces about a few hundred watts of electricity when idle; However, as more devices are connected or turned on, the demand increases and the generator recognizes this and increases its production.

Capacitors are usually able to handle the delay; Capacitors simply charge more slowly (which is barely noticeable under most circumstances), and capacitors act as a rectifier to handle other voltage fluctuations that occur during operation.

For example, if you connect a 220V motor to a 110V source under load, the coils will be energized but the motor will remain stopped.

How many panels do I need to run the lights and water pump?

  • However, the good news is that the water pump should only run for a few minutes on a regular basis.
  • Lights may look slightly different depending on your location.
  • If you have incandescent or fluorescent lighting, I recommend replacing them with LEDs before investing in solar power.
  • In fact, 20 LED lights can sometimes use less energy than an incandescent bulb.
  • To clarify your question, if your RV has the physical capacity to support a 190 watt panel that is 26.3" x 59.06" wide, I recommend purchasing the Go Power Overlander kit from Amazon.

RV Solar Controller protects your batteries

Introducing the new Go Power RV Solar Controller, which features Bluetooth communication for up to two battery banks. A charge controller prevents your batteries from being overcharged during use. A large solar array generates a lot of electricity, which can quickly drain a battery bank if not equipped with the right RV solar controller. Another factor to consider in this situation is the type of battery. Certain batteries, such as B. lithium batteries, provide energy for longer periods of time more efficiently than others.

Many people are at a loss as to the best way to connect their solar panels to their RV.

Sometimes it can be difficult to find pre-wired solar cables on a solar-ready RV.

MPPT controllers have the potential to increase the amount of solar energy reaching your home's battery bank.

How much does it cost to operate my submersible well pump?

Published on the Internet from submersible well pumps are generally accessible in maintenance and operation. In this blog post I will demonstrate the process of calculating the cost of running your submersible pump and motor. Costs can be calculated with just three entries. They are: You need to know the motor's energy consumption (in kilowatts), operating hours (in hours per month), and the cost of electrical energy to do this calculation correctly (per kilowatt-hours).

  • Check your pump specifications and/or data sheet for the maximum power the motor can handle.
  • The number of operating hours is estimated based on the average amount of water used per day and the pump flow rate in gallons per minute.
  • We then divide the number of gallons per day by the pump's flow rate in gallons per minute to get the number of minutes the pump is running each day.
  • Energy costs vary significantly depending on where you live in the United States.

The average cost per kilowatt hour is $0.12 per kilowatt hour. To calculate the total monthly cost for each month, multiply the three variables (energy consumption, hours of use and electricity costs). Known parameters include:

  1. O motor de 12 hp consome 960 watts
  2. Pump flow rate is 10 gallons per minute
  3. house for 4 people
  4. Electricity is $0.15 per kilowatt hour
  5. A 12hp engine is not recommended.

Do the math: the motor's power consumption is 960 watts divided by 1000 = 0.96 kilowatts. Hours of operation are as follows: 4 workers x 120 gallons per day = 480 gallons per day dividing 480 gallons per day by 10 gallons per minute equals 48 minutes per day of operation. 48 minutes a day multiplied by a month (30 days) equals 24 hours a month. Electricity costs $0.15 per kilowatt-hour, which is a very low cost. Monthly Charge Equals Motor Run Times Hours Run Times Energy Cost = 0.96 Kilowatts times 24 hours per month times $0.15 per kilowatt hour = $3.46 per month For water and wastewater, we are a distributor of pumps, packaged pumping systems for water and wastewater, Onsite Wastewater Treatment Plants, Onsite Wastewater Treatment Systems and Custom Electrical Panels.
