Product Information :
The Onan 3349340 is an Onan engine cooling seawater pump, original equipment Cummins Onan pump, with Bronze construction, neoprene impeller, and a 1-1/2 inch Inlet port by 1-1/2 inch Discharge port. This flexible impeller Raw Water / Seawater Engine Cooling Pump is designed and manufactured especially for engine cooling applications. It has a high volume flow capacity, and a fast flow velocity. This flexible impeller pump is self-priming and provides an efficient solution to most raw water pumping needs. This pump can pass fairly large solids without clogging or damaging the pumps. The design allows spare parts to be easily replaced. This engine cooling pump is designed to the demands of engine manufacturers and are built to take rough treatment. This bronze pump is corrosion resistant, and features a high chrome nickel stainless steel slotted drive shaft. Other features of this pump are a convenient drain plug, a machined in cam, flange mounting, and vertical direction in and out ports. This pump has 2 separate seals; one on the main pump and one on the flange mounting. 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. The pump is constructed from marine quality bronze and stainless steel for ruggedness and reliability. 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. It will not air Lock - the pump will continue to operate even when air passes through the system, and it delivers a smooth even pulsation free flow. These pumps are designed to be fully serviceable and after long use can be restored to like new condition, avoiding complete pump replacement. 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.

Applications
Typical Applications for the 3349340 pump are for Engine Cooling. This flexible impeller pump is selfpriming and therefore, it is ideal for engine cooling. This pump is designed for and used on the following engines Onan Cummins 4B series 250HP, and replaces the Sherwood Pump G1503 G1503. The bronze body and stainless steel shaft are well suited for marine environments. Liquids that are compatible with the neoprene impeller can be pumped including 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. This pump can also be used in other Marine applications such as a bilge pump, deckwash pump, washdown, emptying holding tanks. It can also be used in Industrial applications such as liquid circulation and transfer, emptying tanks and sump drainage, and handling of solids in suspension. This Onan flexible impeller pump combines the priming feature of positive displacement type pumps with the general transfer ability of centrifugals. 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. This pump has a rotating impeller that carries the liquid from the inlet to the outlet port. A vacuum is created as the flexible impeller vanes straighten upon leaving the cam, drawing liquid into the pump. When the flexible impeller vanes regain contact with the cam, they bend and the liquid is discharged from the pump in a uniform flow. Liquids can be pumped in the opposite direction by reversing the rotation of the pump. As a consequence of it's design, this flexible impeller pump can pass fairly large solids.
