[/url], a device that expends energy in order to raise, 

transport, or compress fluids. The earliest pumps were 

devices for raising water, such as the Persian and Roman 

waterwheels and the more sophisticated Archimedes screw 

(q.v.).

   The mining operations of the Middle Ages led to 

development of the suction (piston) pump, many types of 

which are described by Georgius Agricola in De re 

metallica (1556). A suction pump works by atmospheric 

pressure; when the piston is raised, creating a partial 

vacuum, atmospheric pressure outside forces water into 

the cylinder, whence it is permitted to escape by an 

outlet valve. Atmospheric pressure alone can force water 

to a maximum height of about 34 feet (10 metres), so the 

force pump was developed to drain deeper mines. In the 

force pump the downward stroke of the piston forces 

water out through a side valve to a height that depends 

simply on the force applied to the piston.

    We mainly use the pump for cosmetic application. for 

example, we have

    Cosmetic bottles are perfect for skin care and 

beauty products. They can contain gels, creams, lotions 

and deep skin cleansing products. Most jar containers 

come with a shive (a flat plastic shelf that fits inside 

the jar) used to keep the contents free from foreign 

debris (dust & germs). Moreover, jars are designed with 

airtight lids, which keep the contents fresh and ready 

for future use. The most commomly used are
