Quiet running vertical multi-stage centrifugal pumps, supplied with flanges.

The  2SCM  series  consists  of  CENTRIFUGAL  PUMPS  with  two  BACK-TO-BACK IMPELLERS, working in series. The first impeller directly faces the suction opening machined in suction body.  The  second  impeller  is  housed  back-to-back  to  the  first  in  the delivery body. The shape of the impellers transmits a radial motion to the fluid from of pressure and an increase in speed. After leaving the first impeller the fluid passes to the volute in the suction body connected to the second impeller suction chamber where it receives an equal energy increase. After leaving the second impeller the fluid enters the volute of the delivery body and the tapered diffuser which transform part of the  kinetic  into  pressure  energy.  The  axial  hydraulic  thrusts  are  perfectly balanced  by  the  back-to-back  installation  of  the  two  impellers  on  the same shaft, thus avoiding any overload on the motor bearings.

The GCP series pumps consists of a single centrifugal impeller, These pumps have an essential  form  and  are  the  result  of  precise  design  choices,  are  made  to  obtain specific performance characteristics. The impeller, mounted on the end of the motor shaft,  faces directly the suction opening machined in the pump. The shape of the impeller  transmits  a  radial  motion  to  the  fluid  from  the  center  outwards,  with minimum hydraulic loss. The blades inside the impeller channel transfer energy to the  fluid  both  in  the  form  of  pressure  and  increase  speed.  After  leaving  the  fluid passes to the volute and tapered diffuser which transform part of the kinetic energy into pressure energy.
