Product Information :
The Oberdorfer 109MB-J20 is a Bronze Centrifugal Pump and motor unit, with Bronze Impeller, Buna Mechanical Seal, 416 Stainless Steel shaft, 1-1/4 Inch NPT Inlet by 1 Inch NPT Outlet Ports, close coupled to a 1/2 Horsepower, 3450 RPM, 115/230 Volts, Single Phase, TEFC (Totally Enclosed Fan Cooled) Motor. This close-coupled pump and motor unit uses a standard NEMA 56J Flange Jet Pump Motor with weld-on base and threaded shaft end to accept the pump impeller. It has a single phase motor that is non-reversible and is wired for the proper pump rotation which is counter- clockwise looking at inlet end of pump. 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 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. 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.

Applications
There are many applications that the Oberdorfer 109MBJ20 are used in. This pump is typically used as a standard pump in the Marine Air Conditioning Industry. The special pump alloys used in this pump provide corrosion resistance to many liquids including water, water solutions, and a wide range of commercial chemicals. Viscous liquids with a maximum viscosity of 2000 Saybolt Seconds Universal can be pumped, however, when pumping viscous liquids as compared with water, a reduction in flow and pressure occurs and the required horsepower rate increases. Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity. Liquids contaminated with small solids or abrasives can be handled, but a reduction in mechanical seal life must be expected. This pump will pump continuously, producing high flow rates under lowhead conditions. Designed for continuous lowpressure circulation and transfer of nonflammable liquids, utility, boiler feed, general transfer, filtration, cooling towers, condensate return, marine applications, fountains, boosters, water circulation, irrigation, spraying systems, jockey pump service, chemical processing, aggressive liquid applications and other generalpurpose pumping compatible with pump component materials where no suction lift or no selfpriming is required.
