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.

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.

While markets for large industrial and municipal pumps often draw the most attention, there is a thriving market for smaller pumps for commercial buildings—even though the two markets are as different as apples and oranges. Experts Tim Zacharias, president of Cougar USA, and Devin Carle, the president of Hurley Engineering, explore those differences.
