This series consist of pumps with a single or multi centrifugal impeller. These pumps have an essential form and are the result of precise design choices, made to obtain specific performance characteristics. The impeller, mounted on the end of the motor shaft, directly faces the suction opening machined in the pump body.
The shape of the impeller transmits a radial motion to the fluid both in the form of pressure and an increase in speed. when the fluid leaves the impeller, it passes to the volute and tapered diffuser which transforms part of the kinetic energy into pressure energy.
