Five pumps or water-raising machines are described by al-Jazari in his monumental treatise of mechanics Al-Jami' bayn al-‘ilm wa 'l-‘amal al-nafi' fi sina'at al-hiyal (A Compendium on the Theory and Useful Practice of the Mechanical Arts). The following long article is a detailed study of the third of these water-raising devices. The study presents a detailed analysis of the mathematical and mechanical principles of this sophisticated machine and explains its functioning. Further, the various components of the pump are reconstructed via computer assisted design. A profusion of 3D graphics and 3D animations show the device in different angles and helps in viewing it in operational mode.
