Even though the first centrifugal pump was introduced about 1680, kinetic pumps were little used until the 20th century. Centrifugal pumps include radial, axial, and mixed flow units. A radial flow pump is commonly referred to as a straight centrifugal pump; the most common type is the volute pump, illustrated in Figure 4.
