Single-Stage Centrifugal Pump with Single-Suction for Water Supply and Pressure Boosting - NB 40-160/172 AF2ABAQE

Single-stage centrifugal cantilever monoblock pumps NB, NBE are designed for pumping liquids in water supply systems, industrial pressure boosting systems and systems for pumping process liquids, ventilation and heating, as well as irrigation. NB, NBE pumps with horizontally arranged shaft, axial suction and radial discharge connections are available with cast iron or stainless steel flow sections and with cast iron, stainless steel or bronze impellers. The pump shaft and motor shaft are coupled by means of a coupling.

NB pumps are equipped with a standard fully enclosed electric motor cooled by an integrated fan of energy efficiency class IE3. The mechanical design of the NBE pumps is identical to that of the NB pumps, but these pumps are equipped with electric motors with integrated frequency converter with energy efficiency class up to IE5. All pumps conform to ISO 5199.

The suction and pressure flanges comply with the...
