Product Information :
The Oberdorfer 101M is a Bronze Centrifugal Pump end only, no motor, with Bronze Impeller, Buna Mechanical Seal, 3/8 Inch NPT Inlet by 3/8 Inch NPT Outlet Ports, replacement pump end only without a Motor. 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 ODP or 1/2 HP TEFC 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 9 GPM with a maximum pressure of 12 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 101M 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.
