Pump selection, Part 2 -- performance curves: The fundamentals of pumped water systems.(Brief Article)

From: National Driller | Date: February 1, 2002| Author: | Copyright information

An understanding of pump performance curves is an important part of a pump installer's storehouse of knowledge. It is crucial to pump selection, and sometimes can mean the difference between an efficient water system and one that is marginally operable, leading to frequent callbacks.

Last month, we began this miniseries on pump selection with a look at the simplest of pump curves -- those showing only pressure and flow, as are typically seen for residential submersible pumps. When the capacity and horsepower requirements of a pumping system go up, pump specifiers may need ...
