Pump Impellers – The Types & Their Impact
Of all pumping technologies centrifugal pumps are the widest known thanks to their efficient handling of many fluids. However, the specification of the right centrifugal pump for an application involves various considerations; one being the choice of impeller/s. But what is an impeller?
Description
Points to Consider in Impeller Selection
The impeller is the rotating component within the centrifugal pump design, which transfers the energy from the pump’s motor to the fluid. It is made up of vanes that come off an open inlet at the centre, known as the eye, which create a centrifugal force as they spin to move the liquid from the casing to the discharge point.
There are several types of impeller, each of which offer different performance characteristics that make it more or less suitable than the others for a particular application. Given the vital part it plays in a centrifugal pump’s operation, you can see why the type and size of the impeller is an important factor in pump specification. But what exactly are the differences and when do you choose which? This article will cover just that, but if you’d rather a quick summary
