Oberdorfer # 30PBS-11 Bronze Self-Priming Centrifugal pedestal Pump end

The Oberdorfer 30PBS-11 is a Bronze Centrifugal Pedestal Pump end only, no motor, with sealed Ball bearings, Keyed Shaft, with Bronze Impeller, PTFE Teflon Mechanical Seal, Stainless Steel shaft, 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 close-coupled pump end only requires a standard NEMA 56J Flange Jet Pump Motor with a weld-on base and threaded shaft end to accept the pump impeller. It requires a 3450 RPM, 1/3 HP to 3/4 HP motor. The pump uses a mechanical type shaft seal with a Teflon PTFE rubber element. It is suitable for virtually all industrial chemicals, corrosives and solvents - as limited by compatibility of basic pump metal of construction. 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.
