Centrifugal pump is often thought of as the simplest and most widely used of all the various pump types. A centrifugal pump has a rotating impeller, within a casing, which imparts radial velocity to the liquid, which then exits the pump by way of the discharge nozzle. The flow is smooth and will change according to the system backpressure. Centrifugal pumps: Sizes from 1 GPM to 100’s GPM. Are made in materials from CI to Titanium and CPVC, PP, PVDF and many others. Produce moderate pressures 1 PSI to 100’s PSI. Can handle liquids that are less viscous than water, up to 300 SSU on a practical basis. 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.
