The invention of the pump dates back to antiquity. The first pump for fighting fires, a mechanic who invented the ancient Ktesiby was described in 1. bc. er. Ancient Greek scientists Heron of Alexandria in his work Pneumatica, and then M. Vitruvius in his work De Architectura.

Simple wooden pumps with a through piston for lifting water from wells, probably used even earlier. Prior to the 18 century. Piston pumps, compared with water-lifting machines were rarely used. In the future due to rising water demand and the need to increase the height of its filing, especially after the steam machines, pumps have gradually displace the water-lifting machine. Requirements to them and their conditions applications become more diverse, so along with piston pumps are rotary pumps to create, as well as various devices for pressurized fluid. Thus, historically, there have been three direction for their future development: establishment of piston pumps, rotational, hydraulic devices with no moving working parts. The rise in the development of reciprocating pumps observed in the late 18 century.

When to make them began to apply the metal and use the drive from the steam engine. Since the mid 19 century. have been widely implemented in the production of steam Self-acting piston pumps. This period is the creation of vane pumps, the prototype of which is the piston with an annular cylinder, described the French engineer A. Ramello in 1588 (Le diverse et articiose machine). Development of the theory of piston pumps is closely linked with the work of local scientists and engineers (C.
