Oberdorfer # N211M-F34 Bronze Rubber Impeller Pump and Motor 1/3 HP
Product Information :
The Oberdorfer N211M-F34 is a Bronze Flexible Impeller Pump and Motor unit with a Neoprene Impeller, Buna/N Lipseal, 3/8 inch FNPT and 3/4 inch male garden hose Ports, close coupled to a 1/3 Horsepower, 3450 RPM, 115/230 Volts, Single Phase, ODP (Open Drip Proof) 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. Other features of this pump are a convenient carrying handle, a motor shaft slinger to protect the motor bearings, and rubber motor grommets for noise isolation. This unit, when using factory motor, meets the U.S. Coast Guard Ignition Protection Requirements, 33CFR 183.410(a). 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. Motor drive is clockwise facing pump end, and the liquid flow direction is right to left facing pump end. The correct AC voltage must be supplied to motor - 115 or 230 volts AC as specified on the motor name plate. 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 10 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. 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. The motor on this pump has open drip proof construction, is rated for continuous duty operation and has built-in overload protection. Motors are 48/SPL. frame size with NEMA standard mounting flange, stainless steel shaft and ball/ball bearing construction.

Motor drive is clockwise facing pump end, and the liquid flow direction is right to left facing pump end. The correct D.C. voltage must be supplied to motor 12 volts DC as specified on the motor name plate. On initial startup pump must be primed to prevent dryrunning of the impeller.
