INTIAL JET 4-4

Peripheral pumps have higher head

coefficients and steeper characteristic

curves than side channel pumps.

As the flow rate increases, peripheral

pumps' input power decreases.

Multistage pumps are peripheral

pumps that have multiple blade wheels

arranged at the different diameter levels of the impeller.

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.
