Oberdorfer close-coupled pumps use a standard NEMA C-Flange Jet Pump Motor with weld-on base and threaded shaft end to accept the pump impeller. Proper pump rotation is counterclockwise looking at the inlet end of the pump. Three phase installations must be checked for proper rotation when pump is installed as interchanging any 2 wires in a 3-phase system will reverse motor rotation.
The 109MB model has Rugged Bronze Construction with Teflon barrier seal to protect the bearings as well as reduce noise. Offered with a flexible discharge port orientation alongside multiple shaft and seal options for a variety of fluid and temperature uses.
Standard Mechanical seal is NBR rubber at 212F max temp and 75PSI. Optional FKM and PTFE seals are available for severe solvents, chemicals and elevated temperatures.
Maximum liquid viscosity is 2000 Saybolt Seconds Universal; however, the higher viscosity will lower the flow and require more HP. Higher viscosity fluids as well as particulate in the fluid will reduce seal life-expectancy.
These Centrifugal Pumps are NOT self-priming. The units must be installed for flooded suction (below liquid level). A foot valve in combination with a manual air bleed for vacuum on the suction side will allow suction lift to 15ft.
In centrifugal pumps the HP required will decrease as the pressure increases, a wide-open discharge uses maximum HP.
