Oberdorfer # 30PB-02 Bronze Self-Priming Centrifugal pedestal Pump end

The Oberdorfer 30PB-02 is a John Deere Bronze Self-Priming Centrifugal Pedestal Pump end only, no motor, with sealed Ball bearings with Bronze Impeller, Buna-N/Ceramic Mechanical Seal, 1 Inch NPT Inlet by 1 Inch NPT Outlet Ports, replacement pump end only without a Motor. This pump is a self priming pump with a suction lift of 15 feet without a foot or check valve (25 foot suction lift using a foot or check valve and a filled inlet line). It has a 1/2 inch pipe plug on the tank the top that is for the initial filling of the priming chamber and inlet line, and then the pump priming is automatic thereafter. This pump model is widely used for the pumping of Perchloroethylene, and is also ideal for marine service - air conditioning, bilge service, and sea water recirculating. It must be mounted in the horizontal position. This pedestal centrifugal pump has heavy duty ball bearings suitable for pulley drive applications. It requires a 1750 to 3450 RPM, 1/3 HP to 3/4 HP motor. 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 22 GPM with a maximum pressure of 14 PSI. 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.
