Everything You Need to Know about Electric Motors for Pumps

Everything You Need to Know about Electric Motors for Pumps

Moving large amounts of liquids is no small feat, and throughout the world, pumps have been used to make this job easier. Pumps help move liquids certain distances, and at certain speeds to do the job they are intended to do. The type of pump you want to choose often depends on how far you need to move it, and the volume you are moving. Pumping systems currently account for 25% of all of the industrial motor usage in the United States, and almost 20% of the world's electric energy demands. If you work in one of the many industries that use pumping systems, you may be wondering how to choose the best one for the job or what to look for. Below, we will share about the specifics of pumping systems, and why Adventech motors can help make your system more efficient. 

What Industries Use Pumps with Electric Motors? 

Some of the leading uses for pumps that use industrial motors are for wastewater treatment, water treatment, pumping oil and gas, and use in the food and beverage industries. They can be used to pump water from wells, for water cooling or fuel injection, and to operate cooling towers. Because of their wide range of industry applications, North America accounted for 17.9% of the industrial pump market growth in 2015, and is projected to grow at the rate of 4.9% until 2025 (Source). Other examples of industries that utilize pumps include: 

  • Agricultural usage: Used to pump water for animals, irrigate areas, move slurries, and pressure wash animal homes. 
  • Construction usage: Pumps are used on a daily basis to maintain construction sites, to clean sites with pressurized water, and to lower flood risks by pumping water out. 
  • Emergencies: Pumps maintain pressurized water for fire suppression. Industrial pumps also can prevent flooding in commercial buildings (sump pumps). 
  • Municipal and waste water systems: Complex systems help maintain water pressure for a water network, and can facilitate movement of waste materials. 

What Size Motor is Right for Our Pump? 

Each company must choose the proper size motor for their pumping needs, which vary based on what they're pumping, and at what distance. Choosing the right size is integral to the success of the project, and buyers should consider rounding up to the nearest horsepower needed to prevent the motor from being overworked. If the wrong size is chosen, it can result in a unit that demands more electrical power than needed, and repeated electrical faults. For example, if a pump requires 4.5HP, it is best to round up to 5HP. Adventech can offer fractional sizes up to 1000HP, and can build larger motors upon request. 

It's critical to ask yourself these questions before choosing the industrial motor to run your pumps: 

-What will the daily operation look like for this pump? In some instances, pumps are installed and it is assumed they will operate at the designed rate all of the time. However, many pumps have to operate across a variety of conditions, including a range of operating heads. 

-Will it be operated on a VFD? Maxeff motors are more efficient without a Variable Frequency Drive, but they are compatible if we provide a line reactor as a filter to hide the circuit from the VFD. This still will reduce your operating costs, but they'll max out at about a 10% savings, whereas if you do not use a VFD, you can save up to 25% instead. You are better off removing your VFD and using the Maxeff alone, if this is the case. 

-How much power does the pump need? Choose the appropriate size motor to handle the maximum power demand, so it can operate the pump efficiently across operating conditions. 

How does an efficient motor for our pump systems save money? 

The food and beverage industry is one segment that uses pumps on a large scale and a daily basis, so they're the perfect example of increasing profits with a better motor. Industrial pumps are used for propelling ingredients, products, sanitation water or fluids, and they draw a large amount of electricity. To keep the pump's motor at maximum efficiency and prevent drawing excessive amounts of power, a Finnish study recommends choosing one that is created to save power. They also recommend making sure that the starting torque can be achieved with less power from the motor. Many pumps have a direct relationship between their speed and the power they draw, but because most food or beverage companies have some viscous products (like ketchup), they often have to produce more torque at startup than during daily operations. The difference between the startups and operations amounts draws more amperage every time it starts up, and falsely cause the operators to choose the wrong type of motor. A more efficient Maxeff motor that can run at a consistent speed across operations will save money by keeping products moving seamlessly and with less abrupt power draws. The faster that fluids are moving in an industry like food and beverage producers, the more profit that is created! 

Why Choose Adventech motors? 

When it comes to the industries that use pump systems, there are things like safety, productivity, and profits on the line. That's why it's crucial to trim costs where you can, but also choose something that you can rely on to get the job done. Saving money doesn't actually happen if the product is unreliable and needs constant, costly repair. Instead, switching to Adventech's Maxeff motors for your water cooling systems, emergency response, or construction needs (or any other industrial use) gives you confidence in the motors you are using. Our performance data sheets can give you an accurate portrayal of the costs and profits savings in real companies, and help you decide if they are right for you. We can also outfit your existing framework with new Maxeff motors, and begin saving you money today! Reach out to us for your custom quote today.
