Peerless large split case design from the 1940s being installed in the field. It is named after the Dutch-Swiss mathematician Daniel Bernoulli, who published it in a book “Hydrodynamica.” The principle is applied to various types of fluid flow and is loosely known as Bernoulli's equation. Moreland's pump may have been the first use of a piston rod and stuffing box (packed in a cylinder) to displace water.ġ687 French-born inventor Denis Papin develops the first true centrifugal pump, one with straight vanes used for local drainage.ġ738 In fluid dynamics, Bernoulli's principle states that for an inviscid flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. The emperor Ferdinand II granted him a “privilege” - the equivalent of a patent - in respect of this invention.ġ650 Otto van Guericke invents the piston vacuum pump, which used leather washers to prevent leakage between the cylinder and the piston.ġ675 Sir Samuel Moreland-an English academic, diplomat, spy, inventor and mathematician-patents the packed plunger pump, capable of raising great quantities of water with far less proportion of strength than a chain or other pump. Pappenheim drove his machine by an overshot water wheel set in motion by a stream and was used to feed water fountains. This gear pump made it possible to dispense with the reciprocating slide valves used by Ramelli.

200 BC Archimedean screw pump is designed by Archimedes is considered one of the greatest inventions of all time and is still in use today for pumping liquids and granulated solids in both the industrialized world and in the third world-where it is a preferred way to irrigate agricultural fields without electrical pumps.ġ475 According to Reti, the Brazilian soldier and historian of science, the first machine that could be characterized as a centrifugal pump was a mud lifting machine that appeared in a treatise by the Italian Renaissance engineer Francesco di Giorgio Martini.ġ588 Sliding vane water pump technology is described by Italian engineer Agostino Ramelli in his book “The Diverse and Artifactitious Machines of Captain Agostino Ramelli,” which also included other pump and engine designs.ġ593 Frenchman Nicolas Grollier de Servière creates an early design for a gear pump.ġ636 Pappenheim, a German engineer, invents the double deep-toothed rotary gear pump, which is still used to lubricate engines.
