There are several reasons why engineers typically oversize pumps when designing hydraulic systems. First, they want to build in a margin of error to accommodate uncertainties or changes in design or as facilities evolve. Second, engineers know that fouling, rust, sediment, and increased internal running clearances will reduce performance over time.

To understand how the viscosity of a liquid affects a pumping system, it is important to understand what viscosity represents. By definition, viscosity is the property of a liquid that causes it to offer resistance to shear stress such as that caused by liquid flow, primarily in the area of the pipe wall.

In 250 BCE, Ancient Greeks and Romans used a device called the Archimedes screw: the first water pump, which was shaped as a giant screw and used to raise water. ANSI/HI 14.6-2022: Rotodynamic Pumps For Hydraulic Performance Acceptance Tests provides critical performance test procedures for rotodynamic pumps to ensure they are safe to use.

System design engineers typically “round up” system capacity and losses to leave room for everything from changes during construction and potential facility expansions to fluid viscosity changes and the gradual roughening of pipe surfaces over time. As a result, pumps in the field often run at higher pressures and flowrates than their application requires.
