The propeller in an axial-flow pump is the main rotating component of the pump and its design. By spinning the propeller at a certain speed, the flow and head can be […]
There are many pump designs that fall into the positive displacement category but, for the most part, they can be nicely divided into two basic groups. The reciprocating group operates […]
Rotary pumps are positive displacement pumps that utilize rotary, rather than reciprocating, motion in their pumping action. They can be designed to pump liquids, gases, or mixtures of the two. […]

The constant pressure booster not only adds pressure to the incoming water (boosts), but also provides constant (or nearly constant) pressure at its discharge.
In this tutorial, we will investigate several aspects of centrifugal pump efficiency. First I will define efficiency and give some examples. Next we will examine some of the design criteria […]
Cavitation (from cavity) is defined as the rapid formation and collapse of vapor bubbles or pockets in a liquid, due to dynamic action, and resulting in the formation of cavities […]
