WORKING PRINCIPLE
The series consists of pumps with a single centrifugal impeller .These pumps have an essential form and are the result of precise design choices ,made to obtain specific performance characteristic. 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 from ,the centre outwards , with minimum hydraulic loos .The blades inside the impeller channel transfer energy to the fluid both in the form of pressure and an increase in speed .After leaving the impeller the fluid passes to the volute and tapered diffuser which transform part of the kinetic energy into pressure energy.
