Oberdorfer # 119MP Bronze Centrifugal pedestal Pump end

The Oberdorfer 119MP is a Bronze Centrifugal Pedestal Pump end only, no motor, with sealed Ball bearings with Bronze Impeller, Buna Mechanical Seal, 1-1/4 Inch NPT Inlet by 1 Inch NPT Outlet Ports, replacement pump end only without a Motor. This pedestal centrifugal pump has external independent sealed ball bearings isolated from the liquid being pumped. The ball bearings are grease sealed for life requiring no maintenance or bearing lubrication. The pump uses a mechanical type shaft seal with a Buna rubber element. It is suitable for water, oils, and some mild solvents and it is limited to 212 degrees F. This long-life centrifugal pump delivers high flows up to 90 GPM at 3500 RPM. 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. 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.
