Pumpada suyuqlik takror-takror harakatlanadi. Pumpani piston, torna, g'ildirak, rollar, diafragma yoki palletlar yordamida haydash mumkin. Ba'zi eski manbalarda suv pistonni palanka bilan ishlatish orqali chiqariladi. Pumpaning o'ziga xos egri chizig'iga kelsak, bu yagona nisbatni ko'rsatadigan grafik tasvir.
