Product Information :
The Oberdorfer 405MG-03UGY is a Bronze Flexible Impeller Pump and Motor unit with a Buna Impeller, 1 inch NPT and 1-1/2 inch Hose Ports, close coupled to a Close coupled to a Motor. This bronze pump is corrosion resistant, is constructed from marine quality bronze and stainless steel for ruggedness and reliability, and features a stainless steel shaft. 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. 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. A foot valve at the beginning of suction line is recommended.
WEIGHT : The Oberdorfer 405MG-03UGY weighs 80 Lbs.

Applications
Typical Applications for the 405MG03UGY pump are pumping liquids that are compatible with the BunaN impeller such as fresh and salt water solutions and mild chemicals. Marine uses include Bilge, Washdown, Baitwell and General Transfer. 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.
The impeller must be replaced if it is worn out or has been damaged by debris or by running the pump dry. Symptoms of a defective impeller are low pumping pressure and low flow. To replace the impeller remove screws and cover. Pull out the impeller with nose pliers or two screwdrivers. Be careful not to dent the pumping chamber with these tools. When inserting new impeller, line up key slot in impeller with the key in the shaft. Use oil on shaft and avoid forcing the impeller onto the shaft. The impeller should also be removed for storage periods to prevent the blades from taking a permanent set.
