Mechanical Sealsd breakdown-type seals. This is generally correct, but there are applications for which mechanical seals represent “too much technology,” and services for which they are not suitable (see the introduction to Chap. 8).

Bearingsder the action of radial and axial forces. Their design, therefore, is as critical as any of the other major pump parts; a pump with unreliable bearings is a continual cause of unnecessary outages and maintenance expense.

Special Effect Pumpsaddition is still kinetic, the addition of velocity, but that employ effects other than that of the classical centrifugal pump (see Chap. 2) to do so. At present there are six distinct types of special effect pumps: regenerative, partial emission, induced vortex, viscous drag, impact, and reversible.

Impellers and Wearing Ringsction of its vanes on the liquid and is the only component of a centrifugal pump that does so. The other components, even those that convert kinetic energy to pressure, absorb some energy from the liquid. Given its unique function, the impeller can be considered the fundamental component of a centri
