NCB: bare shaft end-suction centrifugal pumps, 6NCBZ: bare shaft end-suction centrifugal pumps with electric motor, on a base.
The motor unit and the rotating part of the pump can be taken away without removing the pump body from the system piping.
Hydraulics: pump body with dimension and performances according to EN 733 rules (up to 150-400), closed impeller dynamically balanced and with balance holes for the balancing of the axial thrust. Shaft completely in stainless steel, greased ball bearings, flanges (UNI EN 1092-2): up to DN 150: PN16, from DN 200: PN10.
The NCB pumps can be positioned with horizontal, sloping or vertical axis always with the motor upwards .The operating characteristics of the catalogue and label are to be understood for continuous service and with clear water (specific weight = 1000 kg/m3) with a max manometric suction height of approximately 1,5 m. For higher manometric heights and up to a max of approximately 6 m, the characteristics decrease in the various delivery data.
