Oberdorfer 600S-11F13 Centrifugal Pump and motor unit

The Oberdorfer 600S-11F13 is a Bronze Centrifugal Pump and motor unit, with Bronze Impeller, Teflon Mechanical Seal, 3/4 Inch NPT Inlet by 1/2 Inch NPT Outlet Ports, and is close coupled to a 1/3 HP, Single Phase, 56J Frame, 3450/2850 RPM, ODP Motor. The pump uses a mechanical type shaft seal with a Teflon rubber element. It is suitable for water, severe solvents, difficult chemicals, and elevated temperatures. This long-life centrifugal pump delivers high flows up to 70 GPM with a maximum pressure of 19 PSI. These centrifugal pumps are not self-priming. They must be installed below the liquid level so that the liquid flows to the pump by gravity (flooded suction). However, if a foot valve is used at the beginning of the suction line, and all air is bled from the pump by manual priming, the pump will lift on the suction side up to 15 feet. Such a system relies entirely on the non-leaking foot valve for starting capability. This pump operates by liquid entering at the center and being thrown outward radially by centrifugal force. The impeller is not in contact with other pump parts resulting in quiet, efficient pumping action. Consequently, a relief valve is not required.
