The diaphragm pump is an offshoot of a plunger pump. Because of the risk that contamination could travel between the plunger and the cylinder, the diaphragm is safer for microbial processing. This applet is crude but shows how a reciprocating piston (plunger) pump works.

In the 200s BC, the Greek inventor Ctesibius made a reciprocating pump for use with water. About the same time, the Greek mathematician Archimedes invented a screw-pump: this was made from a rotating screw inside a cylinder, and was used to drain and irrigate the Nile valley.

Initially he started working on the single acting reciprocating pump. ... The pumping unit consists of the piston, cylinder (Bi-housing body), valves, oil seal, sleeve, compression ring, piston rod and suction and discharge pipes. The pump works on the principle of reciprocation of the piston and the cylinder.
