Course Number: 735

The Pumps textbook explains how pumps are used and the principles of their operation. It covers a wide variety of pumps, including reciprocating pumps and various kinds of rotary pumps. A lesson on special-purpose pumps describes diaphragm pumps and pumps used for corrosive and abrasive materials. The final chapters deal with the maintenance of pumps, including the replacement of packing glands, seals, and bearings.
