The CNH series is made up of single-stage centrifugal pumps with self-priming device, axial suction port, open centrifugal impeller and independent shaft. The self-priming devices is made up of a helical rotor installed in front of the impeller and a rotor chamber which is off-centre in rela­tion to the axis of the centrifugal stage.
The series is made up of range of 2 models with open impeller, independent shaft and standard IEC motor. Mixed construction: pressed/cast stainless steel - AISI 316L (1.4404) - CF3M (1.4409). Investment casting and electrochemical polishing treatment guar­antee excellent levels of surface finish. The pump incorporates a self-priming device which gives the cen­trifugal pump its suction capacity; this component guarantees con­tinuous pump operation in applications handling biphasic fluids.

CNH self-priming centrifugal pumps can be used in industrial appli­cations, for example in the food, dairy and beverage sectors, for tank emptying operations, CIP solution recirculation and for han­dling liquids with a high air content
