History of Reciprocating Pumps
Although reciprocating pumps have been around for over 2000 years, they did not gain wide popularity until 1840 when Henry R. Worthington invented the steam pump. These early, simple machines have evolved into the advances reciprocating products seen today in many industries. During the last 50 years, technology improvements have allowed centrifugal and other pump types to become more popular, and reciprocating machines have become somewhat marginalized. That being said, there are still many applications where reciprocating pumps outperform their centrifugal counterparts. The dominance of these alternative pump types has led to a knowledge gap for positive displacement machines. However, the positive displacement reciprocating pump is still a vital part of industry and will remain in use for the foreseeable future. It is important for those who use the pumps to have a fundamental knowledge of the principles of these machines, what they do, and when to use them.
