Pumps and compressors
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
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
