There are many kinds of water pumps on the market, and choosing the best type for your needs can quickly get pretty complicated. Not only are there many types, but there are also many different brands, each with specific features and varying price points. So, how do you choose the one that will work best for your home or business?
We’re here to help. We’re pump experts and, in this post, we’ll
talk about what one particular type of pumps—centrifugal pumps—do, as well as
what their advantages are. Plus, we’ll also take a quick look at some of the
best in the business, Grundfos pumps.
How Do They Work?
A centrifugal pump, like those from Grundfos, works kind of like a radial tire on a wet road. Both utilize “centrifugal pressure” or force to cause a pressure differential and move water or liquid where it’s desired. Or, in the case of tires, to move it away from where it’s not wanted so that your tires get better traction.
Basically, a centrifugal pump’s motor spins an impeller inside the liquid it’s pumping. This causes enough force to push the liquid through the pump housing and creates pressure inside the pump. This pressure (known as “pressure differential”) then creates the pumping motion, moving the liquid through the pump housing and out to the desired location or piping system.
Advantages of Centrifugal Pumps
There are many advantages to centrifugal pumps, including:
·
They are great for moving more than just water. Some can even transfer
high-viscosity liquids like fuel.
·
They’re compact in design, with all components
essentially wrapped around a short driveshaft.
·
In most designs, the powerful motor is separate
from the pump housing, meaning the liquid being pumped doesn’t come into
contact with the motor. This is what allows it to move flammable liquids without concern of overheating.
·
Most also have impressive seals and thermally
protected motors to guarantee safety further.
· They are easy to install and maintain.
A Closer Look at Grundfos Pumps
Now headquartered in Texas, the Grundfos company employs nearly 20,000 people. The brand was originally founded in a basement in Denmark in 1945. Since then, Grundfos has expanded to encompass over 83 subsidiary companies serving 56 countries around the globe! What’s more, Grundfos pumps are top sellers around the world.
Two of their most popular centrifugal pump models are the CM and the CME. While these two pumps share some common features, they are different. Let’s take a deeper look at each.
The Grundfos CM Model
The revolutionary Grundfos CM is known for being a solidly reliable, surprisingly quiet pumping solution. The compact, horizontal pump comes in either stainless steel or cast iron for further flexibility. Its multi-stage, close-coupled design works well for many applications. It’s also easy to maintain, with a quality Grundfos motor that was built to last.
The Grundfos CME Model
Like the CM, the innovative Grundfos CME is also quiet, reliable, flexible, and comes in either stainless steel or cast iron. Their main difference lies in their motors. Unlike the CM’s mains-operated motor, the CME has a PID controller and an integrated frequency converter. The integrated design provides a plug-and-pump solution and offers energy savings that you don’t see with the CM.
