Product Information :
The Oberdorfer N301M-1 is a Bronze Pedestal Flexible Impeller Pump end only, no motor, with a Neoprene Impeller, Buna/N Lipseal, 3/4 inch FNPT by 3/4 inch FNPT Ports, replacement pump end only without a Motor. This bronze pump is corrosion resistant, is constructed from marine quality bronze and stainless steel for ruggedness and reliability, and features a high chrome nickel stainless steel shaft. Other features of this pump are two sealed extra capacity ball bearings that are spaced for maximum load ability with teflon barrier seals that protect the ball bearings, and a shaft slinger that also provides additional bearing protection. This Pump has one moving part - a tough, long-lived, wear-resistant flexible impeller lubricated by the liquid being pumped. No metal-to-metal pumping action - no gears to jam, clog or become noisy. These pumps are designed to be fully serviceable and after long use can be restored to like new condition, avoiding complete pump replacement. The impeller and cam are easily replaced. The Flexible Impeller in this pump generates high rubbing friction unless lubricated by the liquid being pumped. A lack of liquid will cause the impeller to degrade rapidly. This pump can be driven with either a direct drive with a flexible coupling or a pulley drive can be used. Make sure both flexible coupling halves are properly aligned, and when using a pulley, make sure you do not overtighten the belt. On initial start-up pump must be primed to prevent dry-running of the impeller. This pump is self-priming, and will self-prime at low or high speeds. It will pump instantly, and a suction lift of 15 feet is possible when impeller is wet and pump fully primed. Suction lines must be air tight in order for pump to self prime. The Temperature limits for the Neoprene impeller in this pump is 45 degrees F to 180 degrees F ( 7 degrees C to 82 degrees C). Pumping colder water than 45 degrees F will shorten the impeller life.
WEIGHT : The Oberdorfer N301M-1 weighs 14 Lbs.

Applications
Typical Applications for the N301M1 pump are pumping liquids that are compatible with the neoprene impeller such as fresh and salt water solutions and mild chemicals. Do not pump gasoline, severe solvents or acids. When possible flush pump with fresh water after each usage. Limits of 40 degrees F to 140 degrees F should be maintained. Do not allow liquid in pump to freeze, and when not in use for long periods of time you can drain pump by removing drain plug provided, located at bottom of pump body. Use methyl alcohol based antifreeze compounds such as Zerex, Shell Sone, Pyro Permanent, Permagard, Dowgard. This flexible impeller pump can operate in either rotational direction. It combines the priming feature of positive displacement type pumps with the general transfer ability of centrifugal pumps. It will pump either thin or viscous liquids and can handle more solids in suspension than other types of rotary pumps. It operates at low or high speeds can be mounted at any angle and pumps in either direction with equal efficiency. Direction of shaft rotation determines inlet and outlet ports. Prior to installation, rotate the pump manually in direction of rotation to set flexible blades in direction desired.
