Oberdorfer Centrifugal pumps use a standard NEMA C-Flange Jet Pump Motor with weld-on base and threaded shaft end to accept the pump impeller. The 300 Series Pumps must be operated in a horizontal position.
The 300B 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 Nitrile rubber at 212F max temp. 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 self-priming with a lift of 20 FT. Suction lift beyond 15 FT requires a foot or check valve and filled inlet valve. On top of the housing is a 1/2" filler port for initial setup or reset after a dry drain of the system. In centrifugal pumps the HP required will decrease as the pressure increases, a wide-open discharge uses maximum HP.
