An electric generator for the production of alternating current and voltage.

An electric motor driven by alternating electric current.

A physical object intended to compress and supply air or gas at medium pressure and medium volume flow.

A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.

An electric generator for the production of direct current and voltage.

An electric motor for operation by direct current.

A physical object that is intended to deliver or exhaust volumes of vapour or gas at low differential pressure.

A turbine that compresses air which is then mixed with fuel for combustion and expansion through a turbine section to generate relatively high power output for either mechanical drive or power generation.

A motor that is intended to generate power by means of high pressure oil.

A motor that is driven by compressed gas. Typically air.

A positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.

A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.

A thermodynamic turbine in which steam is made to do work by expanding so as to create kinetic energy by acting on moving blades attached to a disc or drum.

An expander of the turbine type used to reduce the pressure of a gas flow by leading it through a turbine rotor by which the recovered energy is transferred into rotational energy for either power generation or mechanical drive application.
