Often thought of as the simplest and most widely used of all the various types pumps, centrifugal pumps have a rotating impeller, within a casing, which imparts radial velocity to the liquid, which then exits the part by way of the discharge nozzle. The flow is smooth and will change according to the system backpressure. Some can handle suspended solids. Not inherently self priming can be adapted to be. Applications such as chemical transfer, wastewater, slurries, plating solutions, cooling systems, where a smooth, consistent flow rate is need. Centrifugal pumps can handle liquids that are less viscous than water, up to 300 SSU on a practical basis. Look no further than Pumpbiz.com for the top centrifugal pumps on the market.
