Did you know the American manufacturing industry employs almost 12 million people?
This figure alone means your manufacturing business has stiff competition. As such, you must have the right component for your machines. One of these is the water pump impeller since it moves the water.
If you want to buy a pump impeller, you will likely feel confused. With the variety of models in the market, choosing the best one is a challenge. Read on to find out where to start:
First, assess your purpose for the impeller. Learn in detail what you would use it for and to what extent the expected wear and tear would be.
Also, know the different types of impellers for pumps to see which one suits your requirements. Here are some examples:
When selecting the right type, you have to consider four major factors. These are solid handling, duty, strength, and efficiency.
The flow pattern dictates the type of pump impeller you should get. For an axial flow, the vessel needs a pitched blade turbine. It’s common in liquid-liquid blending and heat transfers.
For gas-liquid dispersion, a radial flow is suitable. It has a higher shear, requiring the use of crossed blades. You also have to consider if the flow is tangential, which needs an anchor or a square type.
Type of Material
What media or fluid is going to pass through the impeller? Does it contain solids? How corrosive is it?
The design and material of the impeller play a role in how well it can move certain liquids. The viscosity, temperature, and such are vital factors, too.
A centrifugal pump impeller, for example, is best for thin liquids. Impellers in API process pumps can handle crude oil.
What type of pump is housing the impeller? A flexible impeller pump needs a flexible impeller, for instance.
The diameter of the vessel dictates the size, but it also depends on the flow pattern. The impeller should be a third of the vessel’s radial and axial flow measurements. Choosing the right size is crucial as it determines the pump’s efficiency.
The costs associated with an impeller go beyond the initial price tag. They also include maintenance fees.
It all depends on the material and durability. Low maintenance pump impellers are usually the best choice as they save you money in the long run.
The initial costs are higher for a quality impeller. Still, it gives you a higher return on investment because you spend less on maintenance. It also boosts productivity as it spends more time working.
