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.
