Peripheral pumps,
 also referred to as regenerative pumps
 (also see Side channel pumps),
 are centrifugal pumps whose impeller
 (see Peripheral impeller) 
rotates in a largely concentric 
casing channel with an inlet and an 
outlet opening. 

Peripheral pumps operate 
by means of an impeller characterised 
by a large number of
 small dual-flow radial blades
 (with dual input) 
arranged along its peripheral area.

 The centrifugal forces inside the rotor 
generate a circulatory flow between
 the impeller and the casing channel.

 A pump is a device that moves fluids
 (liquids or gases), or sometimes slurries,
 by mechanical action,
 typically converted from electrical 
energy into hydraulic energy. 

On the other hand, 
they have a better capacity. 
Another very striking advantage lies
 in the fact that these products 
are very inexpensive to purchase. 

For these reasons, they are widely
 used in the home to pump clean water , 
without abrasive particles or chemical liquids.
