About this site

The Ram Pump Knowledge Base is an independent educational reference. Technical figures quoted across the site (efficiencies 60–80%, drive-pipe 3–7× rule, historical dates and attributions) follow the consensus of the sources above; where sources disagree — notably on efficiency nomenclature — the discrepancy is flagged in the text. All illustrations are original schematics drawn for this site and are deliberately not to scale. No affiliation with any manufacturer is implied by mention.

The site is a static HTML/CSS/JS build with no external dependencies: it works offline, from a file, forever — much like its subject.
