The Downton pump is type of positive displacement pump patented in 1825 by Jonathan Downton. It was typically used on ships.

The design of the Downton pump sought to create a more constant flow of pumped liquid, and a steadier load-state on the pump, by increasing the number of buckets operating in the pump. These buckets were actuated by means of a rotating crankshaft and connecting rods, which caused the buckets to reciprocate up and down, with each feeding the next with liquid. Hebert (1836) contains a description and cut-away illustration of an early Downton Pump.

Power source

The power source for the pump could be either mechanical or human, with human powered Downton pumps being operated by means of a capstan.
