Centrifugal or kinetic pumps: they have uniform and adjustable flow velocity, thanks to a rotating impeller. Paper and petroleum industry. Chemicals. High temperature and marine applications With radial or axial flow Pumps and compressors Positive displacement pumps: force liquid to flow in proportion to decreasing pump volume. Hydraulic systems, for instance They are machines for compressing air. They are used in pneumatic machines as motors Road drills, paint sprayers and dentists’ drills. They can be reciprocating or rotary With pistons , plungers or diaphragms. (From under 2 to over 8 absolute atmosheres) According ton the air pressure generated, there are low pressure, medium pressure, high pressure and very high pressure compressors With gears, screws or vanes
