To simplify the installation of horizontal-shaft units, these machined surfaces are usually part of a conmion baseplate on which either the pump or the pump and its driver have been prealigned.

,Einleitung. Historische Übersicht,addition 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.

Classification and NomenclaturePumping can be defined as the addition of energy to a fluid to move it from one point to another. It is not, as frequently thought, the addition of pressure. Because energy is capacity to do work, adding it to a fluid causes the fluid to do work, normally flowing through a pipe or rising to a higher level.
