This close-coupled pump uses a standard NEMA C-Flange Jet Pump Motor with weld-on base and threaded shaft end to accept the pump impeller. Single phase motors are non-reversible and are wired for the proper pump rotation which is counter-clockwise looking at inlet end of pump. See the dimensional drawing. Three phase motors must be checked out for proper rotation when pump is installed. Interchanging of any 2 wires in a 3-phase system will reverse motor rotation. The pump uses a mechanical type shaft... Go


Oberdorfer™ centrifugal pumps have a single rotating metal impeller. Liquid enters at the center and is thrown outward radially by centrifugal force. The impeller is not in contact with other pump parts resulting in quiet, efficient, pumping action. The flow produced is not positive which permits the discharge line to be shut off completely without danger of overloading motors or bursting lines. Consequently a relief valve is not required. The liquid flow varies directly as the pump speed—the higher... Go


This close coupled style bronze self-priming centrifugal pump is equipped with high quality ball bearings permanently filled with grease for maintenance free operation.  The main shaft seal is a mechanical face type seal of proven reliability.  Unlike positive displacement pumps centrifugal pumps have larger internal clearances as the pressure is generated by centrifugal force and high liquid velocity.  These pumps can handle impurities in the liquid and the flow in the discharge line may be throttled...
